Splunk Enterprise Security Reviews

I work in the pharma industry, and I use Splunk to aggregate all my reporting logs for my firewall and Active Directory logs. We have anti-spam, web application firewalls, and other solutions to secure our perimeter. We use Splunk for log management and have a stack to transpose a log from the firewall to a VM. When we directly feed the firewall logs to Splunk, they become intermittent and freeze. 

The biggest benefit is that we can manage all the logs from every device on a single dashboard. I can put the log from the core system into Splunk to analyze for abnormal behavior and show that to the developer to improve it. Splunk can also analyze our security devices for security posture for CRM and ISO requirements, helping the organization obtain its ISO certificates.

We started to see the benefits of Splunk when we created our first dashboard. Based on the dashboard information, we can get deep insights from the log, where we define a security incident or event and assign a score to repetitive events. For example, we receive brute force attacks, where the hacker attempts to try a thousand or a million passwords. This will trigger alerts on the dashboard or email. We are not monitoring 24/7, so we can get alerts from Splunk. We can detect threats faster from firewalls and antivirus. 

The consolidation helps us identify the source of the threat faster. They can analyze the forensics to dig into information from the log and correlate the devices. A unified log from various devices can simplify the IT team's response and reduce the alert volume by 35 percent. 

Splunk can deliver more information by going deeper. By creating a dashboard, we can identify the root cause of the threat. Let's say I have a firewall from Check Point. Splunk will find the dashboard for Check Point, implement it in our environment, and connect it to the Check Point firewall logs, which are shown on the dashboard. If we request a custom dashboard, the engineer will take longer to complete the task. 

I can create a custom dashboard for the firewall, antivirus, or endpoint protection. This will take time to complete because they need to understand the log type and mitigation of the process from the system or API.

Splunk helps us manage our hybrid environment, including our email system. The main email system is Microsoft Exchange, which is deployed on-premise, and the second is Office 365. There isn't much security for the hybrid environment. We get logs from the web application firewall, the firewall, and the anti-spam solution. 

Splunk should align its security principles with those of other vendors like SentinelOne. Splunk has mature APIs that can communicate with various security applications and devices. Splunk can process more to produce an understandable dashboard.

Splunk's latest version is much better than before. It's more resilient and powered by AI. It can ingest more complex logs. It will be better because we're using the legacy one.

I have used Splunk for around six years.

I rate Splunk 10 out of 10 for stability. We've had no problems as long as we ensure we have capacity planning for the log system, which is growing every second. 

I rate Splunk nine out of 10 for scalability. 

I rate Splunk support eight out of 10. Support was great, and they responded quickly. 

Positive

Splunk is our first SIEM, but we'd like to explore Wazuh more.

It's hard to say whether deploying Splunk was straightforward or complex because sometimes the consultant did the work for us. I handled the operations side, and the consultant did the project itself. It was completed in two days. 

Splunk is expensive. It's based on the data inside the log. If you produce bigger logs, the cost goes up. We pay a license up to a set size, let's say 100 gigabytes, and if we have 101, they charge us for the overage. We pay about a billion Indonesian rupiah. 

There are many cheaper solutions. Microsoft Sentinel is also a little expensive, but there are cheaper ones like Wazuh, Graylog, and Rapid7.

I rate Splunk Enterprise Security nine out of 10. If you want to use Splunk, you can try the free version, which goes up to half a gig. You can feed a log from the Active Directory. If you take that information directly from Active Directory, it will be hard to read. Splunk provides a good dashboard. 

Splunk is an excellent choice for an organization that needs a fully scalable and highly customizable solution. We can customize the dashboard to combine all the device logs. Unfortunately, others still need to learn how to do that. It depends on an organization's needs and resources because it's not cheap.

It's on the higher end of pricing, which can be a significant factor for small organizations with budget constraints. It's more appropriate for the enterprise level and companies with over 500 employees. 

There are many use cases. Most of the use cases are related to security, data integration, and data sources. 

Splunk Enterprise Security helps with real-time detection. When we integrate any data source, if any external IPs or external devices are accessing that data source, we get notified. We get alerts based on the use cases we develop.

Splunk Enterprise Security has improved the incident response time a lot. Splunk is doing log ingestion, and it is also used to search the database for issues. It is ingesting and identifying. All that is happening in a single solution.

Splunk Enterprise Security is very easy to use. We can monitor anything. We can monitor and integrate any type of applications and servers. It is very easy and effective. I work with different security tools, but none of the security tools has these many features.

Splunk's documentation is clear. Irrespective of the environment we are working in, we have clear documentation.

One of our clients is using the Threat Intelligence Management feature. The actionable intelligence provided by the Threat Intelligence Management feature is very good.

I have been working with different vendors. Splunk Enterprise Security is a very effective and user-friendly tool. Whether it is Sentinel, LogRhythm, or QRadar, each one of them has its own limitations, but Splunk has all the features.

Its benefits can be realized very quickly. It does not take lots of days or months.

Splunk Enterprise Security has helped to reduce our alert volume. There is a 60% to 70% reduction.

Splunk Enterprise Security has helped speed up our security investigations.

It is user-friendly. It is more effective than other solutions. The support and help for troubleshooting and the documentation from Splunk make it very effective.

It has multiple features. It has data integration, search, reporting, and alerting.

It does not need any advanced programming. It only requires basic programming.

In terms of features, it does not need any improvement. Everything is good so far. The only improvement I am expecting is the cost of the licensing. Clients are going to other solutions just because of the cost.

I have been working with Splunk for more than 7 years. I have worked with Splunk Enterprise, Splunk Enterprise Security, Splunk Cloud, and on-prem Splunk.

It is very stable. We never had any issues or bugs.

Its scalability is good.

The support from the Splunk side is very good. They provide the best support.

Positive

I have used Sentinel and QRadar. I switched because of the advanced features, support, and good documentation. It is very effective. It is the best solution. The only problem is the cost.

I have worked with cloud deployments and on-prem deployments. Its initial setup depends on the environment. It is sometimes complex, and sometimes, it is very easy. We also get good support from them.

Our implementation strategy has 3 phases. We first go for development, and then we go for Pre-Prod. After that, we move to Prod.

Currently, I am the only one handling the deployment, but when it comes to operations, we need at least two to three people.

It requires maintenance. Generally, 2 people are required, but for my clients, I am the only one who is taking care of the maintenance.

We have seen an ROI.

It is expensive. I work for multiple clients. I am working for more than 5 clients, but most of the clients are switching from Splunk to Sentinel because of the cost. Even though Sentinel is very limited, clients are moving to Sentinel.

I would recommend Splunk Enterprise Security to anyone who is looking for a similar solution. This is the only solution with all these features.

I would rate Splunk Enterprise Security a 9 out of 10. It is stable, user-friendly, and feature-rich. It is very helpful. Even though it is expensive, the stability, support, and technical documentation make it very effective.

I am on the intelligent engineering team responsible for onboarding logs and operationalizing Splunk Enterprise. We have a separate team for creating use cases and other stuff. I onboard logs and manage the infrastructure. When you onboard various logs, it creates different data models and normalizes the fields for compliance.

We have created a few custom use cases for Splunk that have helped us detect threats faster. For example, we set up endpoint-related data models and specialized setups for various scenarios. It's more efficient than some other products I've used. 

Splunk has sped up our security investigations. We can automate some functions using playbooks, like automating scans for perimeter vulnerability. If you have the signatures, Splunk can intervene automatically to block threats according to the playbook. 

Splunk lets us integrate multiple third-party threat intelligence feeds. We can also customize the data models for correlation more than we could with competing SIEM solutions. We can filter out the noise and see our alerts. 

I created some security reports or dashboards. We also have dashboards for user requests related to our firewalls, like Palo Alto and traffic or activity alerts. We can also see where we're getting a lot of authentication failures, etc. We've also created some other custom use cases, like using VPN logs and use cases for analyzing the national origins of repetitive malware. We have integrated some other solutions like Carbon Black EDR or MDR as well as Vectra, which is fully automated with AI. They have their own signatures.

We get decent visibility with Splunk and integration with data visualization tools like Grafana. We also have various threat intelligence feeds that are updated regularly with the latest IOCs and signatures, which we can use for threat hunting. 

The access and identity features could be improved. For example, let's say we have onboarded 65 logs. Now, we can identify the various processes, but we run into trouble when we're updating the processes for AWS CloudTrail, EDR, MDR, and XDR. 

I have used Splunk for the past three or four years. 

Splunk is stable. It has around 97 percent uptime in my environment. 

I rate Splunk Enterprise Security nine out of 10 for scalability. 

I rate Splunk technical support seven out of 10. We rarely rely on Splunk support except for critical upgrades and migrations. Sometimes, we open a ticket if we see a performance problem, and they find a solution. Typically, we find a solution for our issues online in user forums or knowledge bases.  

Neutral

Previously, we used some open-source solutions, Sumo Logic, and Graylog. 

We have Splunk deployed in two environments for different purposes. One is for ITSI, general dashboards, and our APM application. That is deployed in the cloud. We have it in an on-premises environment for enterprise security. We have a cluster that spans three data centers. Deploying Splunk is easy if you have some experience.  Configuring the log sources, managing the indexes, and learning all the features is more challenging. 

Splunk doesn't require maintenance aside from the disaster recovery and DLP aspects. We have a huge environment in different data centers set up for high availability. 

Splunk is expensive, but you can get a lot out of it if you have the expertise and know how to customize it. It's more customizable than other platforms.  In Java or .NET, everything is pretty defined, so you can't do much customization, whereas Splunk lets you customize dashboards, alerts, and reports using SQL. The cheapest solution is always open source, but these products don't have many capabilities. They might work in a small environment. I would recommend trying LogRhythm, ELK, or Google Chronicle.

Splunk is very expensive because we have recently integrated another solution, and 40 percent of the licensing cost is driven by that. 

I rate Splunk Enterprise Security nine out of 10. I would recommend Splunk to others. When implementing Splunk, it's crucial to set up your use cases, onboard threat intelligence and log sources, and create data models. Using simple XML language, you can create a data model and a simple pivot table to generate complex reports. 

Through Splunk Enterprise Security, we have implemented extensive login integration. This allows us to monitor and restrict access for sensitive accounts, such as superuser and master accounts when password rotations occur. If a login attempt is made for such an account, Splunk triggers a real-time workflow that automatically generates a P1 ticket for the Help Desk and IAM Operations teams to investigate and take necessary action.

Beyond real-time monitoring, we have established additional security measures. We utilize locks within JBOS to control manual account check-ins and user server activity, such as password verifications. Splunk ingests logs from any configured PAM solutions, enabling auditors and our technical team to readily access and analyze all privileged activities. We can also generate reports for session management, session logs, and audit logs.

Splunk Enterprise Security can enhance our organization's detection capabilities. While SIEM solutions are essential for most companies, choosing the right one is crucial. Splunk Enterprise Security is a popular option, and its benefits extend beyond technical teams. It can empower audit teams and provide visibility into user activities, including data sharing and out-of-the-box reports. Splunk's strength lies in its flexibility. It can integrate with other tools to fill any gaps in its capabilities. However, relying solely on one tool like Splunk isn't ideal. PAM tools often have built-in auditing and reporting features, but they may not offer the same level of customization or enterprise-wide visibility. This is where Splunk comes in. It provides a complementary solution, offering multiple ways to generate reports and gain insights.

We recently focused on enhancing Splunk Enterprise Security's identity correlation capabilities. This involved integrating it with several chosen applications. One key integration involved moving from Puppet to Ansible for managing privileged access management and performing virtualization tasks. Ansible allows for agentless management, meaning we don't need to install agents on every server. For broader asset management, we leverage CI/CD tools for efficient deployment across all servers. These tools significantly reduce the manual effort required.

Splunk Enterprise Security offers good visibility into multiple environments. However, certain applications in the financial sector, particularly for high-risk activities, still face regulatory or compliance restrictions that prevent them from migrating to the cloud. Despite these limitations, we see forward-thinking institutions like JPMorgan Chase taking the initiative to move lower-risk applications to the cloud. This trend extends beyond finance, with other sectors like healthcare already embracing cloud adoption.

In my assessment, Splunk Enterprise Security earns an eight out of ten for its ability to detect malicious activities and breaches, but only a seven out of ten for taking action.

Once we have an enterprise version set up, Splunk handles the initial identification steps of potential threats, saving us manual effort. I'd even rate Splunk a perfect ten for this initial phase. However, subsequent action items still require manual intervention – a bottleneck we can minimize with additional tools like endpoint security threat analytics that integrate with Splunk. This would enable complete threat modeling, including asset identification and mitigation directly within Splunk. Unfortunately, our company hasn't invested heavily in threat modeling, with a limited team compared to the larger IAM and risk groups. Thankfully, the industry is recognizing the importance of threat modeling, leading to increased hiring in this area.

Splunk Enterprise Security has significantly reduced our alert volume. This has freed up a substantial portion of the IM operations team, who were previously tasked with continuously monitoring for threats and anomalies across various applications, not just spam. By leveraging these threat detection tools, we anticipate being able to reduce IM operations staff by at least 50 percent.

Splunk Enterprise Security facilitates the acceleration of our security investigations, reducing the required time from one week to one day.

One of the features I appreciate most is privileged account threat detection. It identifies suspicious activity associated with fraudulent accounts detected on the endpoints of target systems.

Furthermore, the platform offers threat analysis and reporting that leverages Splunk data. This allows for the detection of irregular user access from machines directly. This functionality is crucial in large PAM environments with thousands of users, as it identifies inactive accounts.

For scenarios where users might not access the PAM portal to change passwords, different policies are implemented. Splunk plays a key role in detecting irregular user activity. By establishing a three-month threshold, we can identify cases where users haven't used their accounts despite not being on leave or vacation. Such instances warrant investigation to determine the continued need for privileged access.

We can automatically suspend or terminate suspicious sessions. We have also customized reporting within Splunk.

There are limitations with Splunk not detecting all user activity, especially on mainframes and network devices. This is because Splunk relies on agents, which cannot access certain workstations. In these cases, we have to rely on application data. For example, with mainframes, manual reports are generated and sent to Splunk, limiting visibility to what's manually reported. This lack of automation for specific platforms needs improvement from Splunk. Additionally, API access is limited for other applications that rely on API calls and requests. This requires heavy customization on Splunk's end. These are the main challenges we've encountered.

Monitoring multiple cloud platforms, like Azure, GCP, and AWS, with Splunk Enterprise Security presents some challenges. While Splunk provides different connectors for each provider, consolidating data from two domains across distinct cloud environments can be complex. However, leveraging pre-built templates and Splunk's data collation capabilities can help overcome these hurdles. Despite initial difficulties, I believe Splunk can effectively address this task, earning it an eight out of ten rating for its multi-cloud monitoring capabilities.

While Splunk Enterprise Security offers insider threat detection capabilities, its effectiveness could be enhanced by integrating with additional tools, such as endpoint security solutions. This integrated approach is particularly crucial for financial institutions, which often require dedicated endpoint security teams. While using multiple tools is valuable, further improvements within Splunk itself are also necessary. Considering both external integration and internal development, I would rate its current insider threat detection capabilities as three out of ten.

Threat detection is where Splunk falls behind. While it offers tools, other use cases require additional work. PAM is an enterprise tool that centralizes information about users, servers, and everything else. It needs real-time monitoring, which I haven't seen in any of the companies I've worked for. They only rely on Splunk for alerting, but real-time monitoring should be handled by the endpoint security team's tools. This means there's no detection or analysis at the machine or endpoint level. Additionally, threat analysis reporting is also absent.

I currently use Splunk Enterprise Security.

Splunk Enterprise Security's scalability and ability to handle large data volumes is great. Splunk can manage a lot of users and applications. I would rate the scalability a nine out of ten.

The technical support is a bit expensive but they respond quickly.

Positive

Splunk Enterprise Security is expensive but the solution is equipped with a lot of features.

My rating for Splunk Enterprise Security depends on the type of logs being analyzed and the company's specific environment and setup. If a company is actively comparing Splunk to competitors and their environment aligns well with Splunk's strengths, then a score of nine out of ten is justified. 

We mostly use the solution for compliance, logging, log storage, and root cause analysis. In 2015, we had AIG as a client, and they only had Splunk. Splunk Enterprise Security is one of the oldest solutions that did the logging and storage.

Splunk has fantastic brand value, which helps us sell it as resellers. The solution's pricing is quite competitive. The solution meets all the requirements. As a compliance person, I know that log storage is very important for data privacy compliance guidelines like ISO or CCPA. Splunk provides all of those compliances and checkmarks.

I like that the tool is light and the agent doesn't slow down the machine. Splunk Enterprise Security is a standard solution providing good customer service and partnership.

The solution should improve regional knowledge of the new regulations coming out of the Middle East. As a consulting firm, we are currently targeting many Middle Eastern markets, including Saudi Arabia and Dubai. They don't have a local server support cloud center there, which is a big issue because they don't want their data to go out of the region. Splunk should have more regional data centers in the Middle East.

I have been using Splunk Enterprise Security for five years.

Splunk Enterprise Security provides good stability.

The solution's scalability is fantastic. Even 10,000 to 50,000 endpoints don't slow anything down. The servers, log storage, and ingestion work smoothly, irrespective of whether there are 5,000 or 50,000 endpoints.

The solution’s technical support is very good.

Our customers using Splunk Enterprise Security don't have any compliance issues, and they don't get fined by the regulators, which saves them money.

Splunk Enterprise Security's pricing is pretty competitive.

I'm a consultant who uses Splunk for other clients. It's important for the clients that it can communicate with all kinds of devices, like firewalls, WAFs, servers, endpoints, switches, and routers. All of that is figured out over time, which is useful.

Splunk Enterprise Security is a good tool for finding security events across multi-cloud, on-premises, or hybrid environments.

Splunk has helped improve our organization's ability to ingest and normalize data. It can also identify and solve P1 or high-critical-priority problems in real-time.

Splunk Enterprise Security has helped us reduce our alert volume by around 50%.

The solution provides us with the relevant context to help guide our investigations, and this context information has impacted our investigation process. Having all the data in a single place does help with post-incident response and forensic root cause analysis.

Splunk Enterprise Security has significantly helped speed up our security investigations. I save 60% to 70% of my time because it's easier to find what I want to find through the tool's user interface.

Splunk Enterprise Security has helped reduce our mean time to resolve by around 50%.

Overall, I rate the solution ten out of ten.

We typically suggest Splunk IT builds for customers with significant EPS requirements and large-scale data environments. While other solutions like Foundry and IBM QRadar may be popular, they often have limitations in handling big data effectively.

It offers visibility across various environments, encompassing diverse infrastructures such as multiple firewalls. Some environments are entirely cloud-based, while others follow a hybrid model with services both on-premises and in the cloud. The infrastructure setup varies depending on the organization's specific model and needs.

We are highly satisfied with the level of visibility provided by Splunk.

It offers advanced threat detection capabilities to assist organizations in uncovering unknown threats and anomalous user behaviors. Splunk is utilized for integrating various devices including firewalls and other security controls, enabling coordination of logs and the creation of use cases. Analysts investigate alerts generated by these use cases, identifying and mitigating potential threats. Additionally, Splunk provides built-in and customizable use cases to enhance security measures.

We utilize the threat intelligence management feature in Splunk, which includes the provision of IOCs. Additionally, we have third-party intelligence services integrated into Splunk, which alert us whenever any related feature is triggered.

The effectiveness of the actionable intelligence offered by the threat intelligence management feature hinges on the third-party engines integrated or enabled within it. While false positives are common and require investigation, there are instances where identified IOCs are indeed malicious. In such cases, actions like reporting or following a predefined playbook can be taken.

We leverage the Splunk Mission Control feature, and I have hands-on experience with it. Typically, I manage it through Splunk, where I create rules, reports, and dashboards. Enabling third-party intelligence and other features involves a thorough review process, particularly when onboarding new clients. Once set up, we regularly review our baseline configuration and make adjustments as needed to ensure optimal performance. The Splunk Mission Control feature aids our organization in centralizing our threat intelligence and ticketing system data management. We integrate third-party intelligence services along with our company's proprietary advisories, particularly in the retail sector. This integration enables us to maintain a comprehensive reference set within Splunk.

We utilize the Threat Topology and Mitre ATT&CK Framework features to enhance our understanding of threats. These features offer micro-mapping visibility, allowing us to align identified needs with specific techniques.

The purpose of the Mitre ATT&CK Framework is to aid in discovering and understanding the full scope of an incident. Using the micro-hypotheses, we assess whether our subcontractors are adequately covered. We evaluate our rules to determine whether we have sufficient use cases for tactics and techniques, such as initial access. This process helps us identify any gaps in coverage within the Mitre ATT&CK Framework and address them accordingly.

Splunk is a valuable service for analyzing malicious activities and detecting breaches. However, I recommend ensuring comprehensive coverage of threats by integrating all relevant devices and maximizing visibility into logs. For instance, leveraging firewall logs enables the detection of anomalies at the network level, while logs from EDR solutions can identify malicious activities on endpoints.

Splunk has significantly improved our threat detection speed. Comparatively, when working with other teams, I've found Splunk to be more efficient due to its big data capabilities, allowing for faster analysis compared to IBM QRadar and similar tools.

The primary benefits our customers experience from utilizing Splunk in their organization are significant. While Splunk may be more costly compared to other machine solutions, its effectiveness shines in handling large volumes of data, making it ideal for organizations with extensive data needs. Unlike solutions like IBM QRadar, which may struggle with processing large amounts of data efficiently, Splunk's big data capabilities enable it to excel in such scenarios.

Splunk Enterprise has effectively decreased our alert volume across various use cases. Whenever we develop a new use case, we carefully analyze it, occasionally encountering false positives. In such instances, we collaborate with IT to whitelist these cases. Over time, as we accumulate a robust whitelist, the ratio of false positives diminishes, resulting in a higher rate of true positive alerts.

It has significantly accelerated our security investigations, proving to be immensely helpful. We can efficiently track and analyze user activities with most devices integrated into the Splunk environment. The visibility provided by Splunk allows us to coordinate activities seamlessly and thoroughly investigate any detected incidents. Whether it's identifying the origin of an activity or uncovering correlations between events, Splunk enables us to piece together the entire user activity chain swiftly and effectively.

Compared to other SIEM products, I've found that Splunk offers quicker alert resolution times. Its ability to efficiently handle large data volumes contributes to this advantage. Analysts typically have predefined playbooks and investigation checklists for when alerts are triggered, which Splunk supports well. Additionally, we've customized dashboards and reports to further streamline our detection process, ultimately reducing our response time.

For those seeking cost-effective solutions, Elastic Stack stands out as a popular choice due to its single-source administration and competitive pricing. Many industries, recognizing its affordability and robust services, are swiftly adopting Elastic and other similar solutions like Wazuh.

The value of resilience in a SIEM solution varies depending on the organization's preferences and requirements. Some organizations prioritize high availability and disaster recovery capabilities, which contribute to resilience.

As an analyst, I've observed that Splunk offers a variety of rule sets, along with built-in and customizable use cases. We have the flexibility to create dashboards and expand reports for management visibility. One key advantage of Splunk over competitors like IBM QRadar is its superior device integration capabilities. With Splunk, we can seamlessly integrate and coordinate data from various sources, enhancing our analytical capabilities.

I believe there is room for improvement in reducing costs, particularly in the financial aspect, as Splunk tends to be pricier compared to other options. Additionally, enhancing support services with more technical personnel is essential. Delays in responses from the technical team can pose challenges for both vendors and clients, especially considering that Splunk applications and machine solutions are critical assets. Splunk's pricing may pose a barrier for some users, but if it becomes more competitive, it could attract those currently using IBM QRadar or similar solutions. Additionally, considering the trend towards migration to Microsoft Sentinel, which offers a comprehensive suite including identity management and EDR coverage with Microsoft Defender, Splunk could benefit from offering similar modules. In Microsoft Sentinel, they offer a separate identity management module, which I find particularly valuable. Any anomalies detected within identity management trigger alerts, providing enhanced security.

I have been working with it for two years.

It provides good stability capabilities.

The scalability of Splunk, particularly when implemented as an enterprise solution, is notable. While we work with a limited number of clients, typically five to six, they are spread across various locations, including the US and Pakistan. From a maintenance perspective, our operations are based in Pakistan. Our clientele predominantly consists of customers from Gulf countries, and we also extend our services to clients in the US.

There have been instances where the response time from Splunk's support team has been slower in comparison to others. I find IBM QRadar and similar solutions to have more efficient support teams. I would rate it five out of ten.

Neutral

Our deployment team handles both deployment and support services, including maintenance responsibilities.

It offers a return on investment for our company.

Overall, I would rate it eight out of ten.

I've been building SOCs for multinational banks across Asia and Australia, the Middle East, and right now in the United States.

It's the tool that we use to build SIEMs to meet logging requirements and to identify security issues across larger states of data sets.

We wanted to give our analysts visibility in near real-time to problems as they occur. That's the goal. 

By using the frameworks that we've adopted, like MITRE ATT&CK and the coverage mapping, we're able to show the divisions that we have in our detection environment. And we map that across with our prevention layers just to describe to the business the deficiencies we have. We can show, for example, these are the areas we can't see since we don't have logging for them, and or these are the areas we can spend more time on to draw down risk due to the fact that, while we have the logging, we haven't got the searches and correlation searches in place. That would perform detection behind the preventative controls. So it gives us a guide as to where we can spend time better.

The feature that we use the most is the correlation search engine within ES. That is the one we use. Absolutely the most. There are a lot of other features in there, however, that's the one we use.

Our organization does monitor multiple cloud environments. It's not "easy" per se. I'm a Splunk-certified architect. I've got 30 years of experience. If you've got 30 years of experience and you're a Splunk-certified architect, it's easy. If you haven't, you've got no chance.

Splunk Enterprise Security's visibility into multiple environments, for example, cloud, on-prem, and hybrid is good. Splunk doesn't care. It's as easy on-prem as it is on the cloud, as it is hybrid. I've built up all three individually and separately depending on the environment.

The insider threat detection capabilities for helping our organization find unknown threats and anonymous user behavior are okay. It can do it, however, it is not out of the box a UEBA. It doesn't pretend to be. Splunk has a separate product for that which is not the enterprise security suite. That said, if you enable the access domain correctly within ES, it gives you really good insight into what your Insight users are doing. That's what the access domain is. However, it doesn't have the advanced features that you would expect from your UEBA product as it is not one.

We use the threat intelligence management feature. My impressions of the actionable intelligence provided by the threat intelligence management feature are mixed. We import anomaly threat intel into the Splunk ecosystem to do that. We use the framework that Splunk provides, and we supplement it with the threat intel from a third party, and that works really well.

We use the MITRE ATT&CK Framework. We’ve mapped all of our detections around that Miter framework. There's there's four frameworks built in, and we chose Miter. It just makes more sense. You only pick one. There’s no sense in picking more than one.

It’s helpful to uncover the overall scope of an incident. If you've done the work to map your MITRE ATT&CK Framework into the product, then you have a hit against a MITRE ATT&CK technique. Then at least you know where it is in the MITRE ATT&CK framework so that you can describe it as a common frame of reference with a third party. However, it doesn't necessarily give you an idea of the scope. It requires more effort. That said, it's certainly a really good starting guide as to where you are.

Splunk Enterprise Security is okay for analyzing malicious activities and detecting breaches. It's only as good as the operators that use it. Out of the box, it doesn't do anything. You have to put the work in to make it do that. I can't begin to say how useful it is when it's first configured. You need to spend a lot of time working on your environment to make it do that.

It helped us detect threats faster. Without it, you can't check anything. It's too complicated.

The solution has helped us speed up our security investigations. Without it, you don't have investigations. Also, with the alerting itself, Splunk becomes best of breed.

Enterprise Security hasn’t helped us reduce our alert volume. The analysts have, however.

We do all of our enterprise security on-prem. We avoid the Splunk Cloud solution since we want the flexibility to build our own. It is a hugely complicated product. Obviously, anything that they could do to make it easier would be ideal. 

I've used the solution for over ten years. 

It's rock solid. It never failed. Having resilience in our organization is fundamental to our security position. 

We're a multinational and have Splunk in the UK and US. We have 2,000 employees, and 2,000 endpoints, at the employee level. We also have around 12,000 production endpoints and it runs across a multi-cloud hybrid that includes GCP and AWS. It also has a tiny on-prem footprint.

You can horizontally scale someone instantly. I've never been afraid we would exceed horizontal requirements. 

We don't use technical support. 

I did not previously use a different solution in this company. 

A long time ago, the company replaced ArcSight with Splunk. 

The initial deployment was complex. 

Our strategy has been to avoid clustering for searching and to build a significantly larger virtual machine for running the ES environment as a stand-alone. It's got 128 cords and 256 Giga RAM so that it can run inside itself and not have to cluster since a cluster adds too much complexity.

We only need one person, myself, to deploy the solution. I'm a Splunk certified architect and I have 15 years of experience doing nothing but Splunk. 

The solution does require some maintenance. We have seven people in total handling maintenance. 

I have witnessed ROI. However, luckily, our center does not have to pay for the license. 

We get enterprise licensing via Intuit, our parent company. The licensing is horrendously expensive. 

I did not evaluate other options. This solution was in place when I arrived. 

I'm an end-user.

If you are looking for a cheaper option, you probably don't have a focus on security or have a risk that you care about enough to purchase a premium solution. If you look at the Gartner roadmap, Splunk is a clear leader, and it's always at the top right quadrant. Everything else is attempting to catch up to Splunk. There's no one else in front of it. If you choose something like Elastic or Sumo, your company doesn't place an emphasis on security. 

I'd rate the solution nine out of ten. It's a lot of work. Almost nothing works out of the box. You have to invest in it for three to five years at a minimum. 

Splunk Enterprise Security has given me quite a context of how I will approach deploying use cases. I'm also using other tools that Splunk sells. The query-based Splunk deployment certainly needs a specific knowledge requirement because knowledge transfer has to be there. There has to be practice on the query side because the query is the main part of understanding Splunk.

In other tools, it's just click and drag where you take the fields from one place and copy-paste them. There is a learning curve in the context of understanding Splunk, which is difficult for every user to grasp within a short time. It is easy to use the solution after having that knowledge. There is a certain learning curve to learn Splunk query language.

With Sentinel, you can click on the field and select it, but with Splunk, we have to write queries to understand what is in the logs and understand certain fields from the logs that are visible to us. We need to know what kind of fields we need, how to create statistics or tables through it, and how to create visibility of reports through query because everything is through query. A query is the main thing for Splunk. There is a learning timeline that users will have to cover to benefit from Splunk because that is something that a user has to be careful about.

We use Splunk Enterprise Security to serve our clients. Our clients from the financial and health sectors deploy the solution in their environment for cloud visibility. Our clients use the solution to find any threats or vulnerabilities inside their environment. We use the solution to get use cases, reports, dashboards, or visibility onto their environment. We use the solution to detect any attack or malicious intent of users inside the environment. We try to create use cases specific to their environment through Splunk Enterprise Security.

Splunk Enterprise Security has a learning curve that needs to be improved. I have seen users struggle with Splunk just because of the language they've used to create it. I've recently started working for the past three months on Sentinel. The same thing happens with Sentinel, where you select certain things, and it will create a query for you.

It would be great if I could have a certain dialogue box in Splunk that uses innovative AI tools like ChatGPT, which are available now in the tech department. If a user is struggling, they can just ask an AI tool what they are trying to do with a query, and then it can suggest how a query can be written for a particular user. It can help in a way to understand the context of what the user is trying to write, which will be very helpful for ongoing operations.

Even if users have zero knowledge, they can get comfortable with Splunk much more easily if an AI tool helps them write a query or search for any indexes or data models. It will be able to give more context to the user regarding how they should approach the query. This can be done using AI tools like ChatGPT, which will understand the context of what the user is trying to approve and give suggestions based on it.

I have been regularly using Splunk Enterprise Security for the last seven months.

Splunk Enterprise Security is stable 70 or 80% of the time. However, the query gets slow whenever a large number of people are working on Splunk.

Splunk Enterprise Security is a scalable solution, but the scalability part impacts the solution's performance.

We have not yet contacted Splunk's technical support, but we do get regular emails from them providing some context of updating something or threats and vulnerabilities. They do provide a certain kind of visibility, which I do like. They provide their clients with insights into what kind of threats might be present or what kind of composition they're trying to resolve. They give quite a library of expertise and particular emails.

The documentation side of Splunk is something that I appreciate as a Splunk user. This is something that is not visible in other environments. Splunk has taken a step ahead compared to other SIEM tools in providing context for understanding the documentation of how the tools work and how you can utilize the tools.

There is a great learning website for Splunk users, where they provide sets of videos. A small environment will be deployed for users to test and understand the queries. That is something which Splunk has invested quite heavily in, which is very much appreciated by the users. We can easily learn Splunk from their environment and understand any attacks happening because they've already provided so much of the content library. That is great from Splunk's perspective.

Our client already had Splunk working for them for the past six to seven years. The earlier version of Splunk was not reliable and stable to deploy because it used to take so many resources. Even though it has decreased now, the resource requirement is much greater than other tools. Certain organizations or start-ups feel a little bit restricted because, despite being a great tool, they can't use Splunk because of its cost features.

Some organizations use basic SIEM tools like QRadar, which is a great tool. Some organizations use LogRhythm. LogRhythm has a market presence since it also writes great insights into the dashboard. Splunk has certain tools that precede other SIEM tools. QRadar and LogRhythm are used because they are very intuitive and don't require any previous knowledge of using those tools. With Splunk, you will have to understand the context of using a particular field or setting and what it provides you.

The ease of deploying Splunk Enterprise Security is very good. You can get visibility on which particular device you are receiving logs from, give them an index name, and give them a field where you want the logs to go. That is something good that we can understand directly from Splunk. We don't have to go and do that manually from different tools. That was one of the good things while implementing the solution.

From the client team, two people were involved in the deployment process. One person was from their implementation team to understand how the tool is deployed. Another person was from the admin team of engineering, where they were trying to understand what resources they needed to deploy to get usability of plans. A third person was there to understand the context of how the log will be initiated into Splunk.

That is something that was required from their environment. From our side, there were three resources with expertise in Splunk. They were the first hands-on people who were working on the implementation side. Later on, I came into the picture so that implementation could be done to create visibility in the client's environment. Before passing and giving them indexes, the context was taken from us by giving us visibility into the environment and how we want to approach it.

US customers or customers with a bigger cybersecurity budget have seen a return on investment with Splunk Enterprise Security because their internal team is using it. They have seen much more return on investment regarding how their environment is visible. However, the majority of Splunk users have faced issues because of licensing purposes.

Companies cut out budgets to include a reasonable SIEM tool rather than having the costliest solution. For certain markets, it serves a purpose and gives a great ROI. One of our customers has said that it's a good investment tool. They have been using it, and they have been getting great insight. It is certainly serving them a purpose, and that's why they are using Splunk Enterprise Security.

Splunk Enterprise Security is a very good tool, but it uses many resources and comes at a very particular cost, while other tools can easily do the work. There are certain pros and cons to using Splunk Enterprise Security.

The solution's pricing will depend on enterprise to enterprise. For a small enterprise, the solution's cost of ingestion to the cloud will be very high compared to other tools. The licensing cost of data usage is much higher for Splunk than any other tool. Splunk Enterprise Security is not at all cost-friendly to be deployed in very small enterprises like start-ups. Using Splunk for small enterprises is unreliable, and I rate the solution two or three out of ten for its pricing in small enterprises.

I rate the solution five out of ten for its small to medium-enterprise pricing. If they deploy it and have expertise, Splunk Enterprise Security will give them more visibility into their environment. This tool will require licensing costs. If they don't have more environments from where they ingest logs, their data licenses will also be less.

If large enterprises can afford Splunk Enterprise Security, they must select it since the experts working on Splunk can give much more complex insight than any other tool. For large enterprises, it's a great tool for visibility because it can create complex queries, including two different indexes. That is something quite unique about Splunk Enterprise Security.

I am working with the cloud version of Splunk Enterprise Security.

Splunk has certain kinds of health issues that usually get reported. If the search query is lagging, we do check where the query is lagging. That is something that we have to refine. It's a hectic activity, which requires the workforce to understand the context because not every user with a simple understanding of Splunk will be able to do it. It requires understanding how the queries are running, how it is scheduled, and how it uses the resources.

Two sets of people work on it: the analyst from our side and those directly using resources from the client side, who work in their security department. They might have some precedence in the environment, which we might not have. We may face lagging of query and, sometimes, queuing of the query, even though we have run it. It will be the first query we are running, but it will be skewed since we don't have the precedence of running a query.

It will give precedence to other queries over ours. It's a thing that we have to manage. This usually doesn't happen with other SIEM tools. That is something where Splunk has to be less expensive or less maintenance. We are struggling because we only identify after the query has gone rogue to invest in it and spend more time resolving issues.

Until now, I haven't used the threat intelligence management feature or even the data model. I use the documentation provided by Splunk on different attacks, which we can view on their site. They already provide insight into attacks on Active Directory or AWS in their documentation library. That gives a good context of how I can search for the different kinds of attacks.

I'm also automating some of the reports on how I challenge threat intelligence. I'm also doing threat hunting in their environment for some of our clients. I'm trying to find any anomalies with the configuration in their environment, which they are unaware of.

Suppose someone gets a response from their environment regarding weak encryption or a configuration that provides certain privileges to certain users, like any query or command line. We find great visibility from their documentation side. We will need time to get acquainted with Splunk threat intelligence management.

Earlier, I started using Splunk Enterprise Security in 2021. I had a trial with Splunk Enterprise Security and contacted the Singapore team to understand the solution. I was working in a startup and wanted to integrate this solution. I was able to get a trial period for three months. I was able to deploy it on the whole server and learn about the Splunk query language. After the trial, we couldn't purchase Splunk as it's a costly tool.

I initiate use cases, analyze the logs, and implement new logs. Since Splunk supports add-ons specifically for different services, we have created plug-ins to integrate any new AWS logs. Implementation of logs also falls under our category. My main job is cybersecurity. I need to understand all the logs to create use cases that cannot be specifically created by a single person who only understands the injection. The context is important to create the use cases.

We use Splunk Enterprise Security to create visibility into the client's environment and research the threats or vulnerabilities inside their servers. We're trying to detect any vulnerabilities regularly by creating specific reports for our purposes for some exploitation, which can happen if you get certain kinds of privileges. Whenever something malicious happens, Splunk Enterprise Security will send us a report containing that specific activity's data.

I can create specific queries to get reports, which I have not observed in other tools. The same can be replicated for the dashboard or vice versa. Splunk already provides a library of use cases regarding attacks. Their website also has a great amount of documentation on how to search for different kinds of attacks in an environment using certain scripts.

It's very good for users to go through their documentation. Users need not purchase a second solution or outside inventory to get visibility about the kind of attacks they can see. That is something Splunk has already prepared for its clients or users.

Everything concerning Splunk Enterprise Security is quite different from other tools. Splunk Enterprise Security has features that are very different from other vendors. These features include viewing correlation or drill-down searches of specific use cases, mapping those comments, and closing any alerts triggering the incident review.

The solution gives us some visibility on the use cases directly. Query is one of the strongest things that Splunk has. With the respective data models, we can create queries running much faster than other environments.

Splunk Enterprise Security gives certain advantages of deploying and automating some of the things we usually do manually in other tools. One of the biggest advantages of the solution is that we can detect threats and vulnerabilities in the environment by creating certain dashboards that give visibility. We can create certain reports, giving us continuous activity reports of anything malicious. We can schedule it at a specific time and send it as a mail.

That gives Splunk a greater advantage of providing insight to the person trying to see any kind of threats or visibility. The solution is intuitive because it lets you choose how you want to be notified regarding any kind of threat. I can correlate from one index to another by correlating searches by stretching one of the fields from one index and then searching for that information in another index. That is not quite possible in other tools and is unique to Splunk Enterprise Security.

With Splunk, we can correlate between any kind of endpoint device, what IP they are mapping through, and search the firewall in the same query whether that IP was allowed or not. It's a very intuitive tool that allows us to create multiple complex queries to solve a problem in a single go rather than opening different instances of different devices and then comparing them manually.

We deploy all of our use cases and reports with respect to the MITRE ATT&CK framework. We write the tactics and techniques of the MITRE ATT&CK framework inside the use cases because there are fields we can fill in about the MITRE ATT&CK framework. It is very useful for us to monitor what kind of MITRE tactics and techniques we have already covered. For anything missing out, visibility is also great so that we can monitor all the users with respect to the MITRE ATT&CK framework.

In our organization, rather than using only the field change, which covers only some parts, we always deploy use cases with respect to the MITRE ATT&CK framework. We have assessed specific use cases for every environment, whether Windows or AWS. We cover certain default use cases, which we want to create in the environment for covering the MITRE so that those are crucial for discoverability whenever something triggers.

Those are also crucial whenever we want to see how much coverage we have according to one device, like Windows log, Linux log, or AWS or Azure environment. If there is any scope of vulnerability present, someone might be trying to attack AD, and the MITRE ATT&CK framework covers it. On the MITRE ATT&CK framework side, I can put a technique they're using for a threat that might be present for initiating the attack. That gives us great visibility of providing threats.

When we are filling out the MITRE ATT&CK framework, any person from cybersecurity will be directly able to copy-paste any technique onto their Google search. They will be able to know what kind of MITRE technique we are trying to cover and how the use case will help them. That can already be done from a use-case perspective. We don't have to go to the library to know how we deployed the use case. That can be done from every different alert.

There are glitches and notes, and it gives more context with respect to the sensing tool. The main field is the activity field, where jobs are there. The usability of that particular feature, where I can see which particular job they're running, gives context to us on how the query is being run in the back end and how they are scheduling it.

If I don't have certain admin privileges, I might not be able to schedule my query. It will certainly give precedence to the admin account, and if I want to see great visibility into the search I'm doing, it will take a certain time.

Only after a certain privilege query is being run will it give precedence to my query. That is something where the distribution of resources can be separate. A separate tool can also be created for giving certain privileges to temporary users so that they can run their queries to find any threats or vulnerabilities. Also, not every query for admin needs to be run at certain privileges. It can be asked during the time of deploying whether this query requires a certain precedence.

Splunk already has specific definitions for finding threats. It can be through a network or a signature. They already have different kinds of internal assessments of how we're deploying use cases and how Splunk understands it. The same can be given to users because sometimes when we try to search for any threats, it gives precedence to other things. Even though the tool is good, it takes time to give us visibility because of the involvement of so many resources.

On the admin side, if I have certain privileges and everything is running fine, I have great visibility on understanding the use cases and deploying correlation between two different indexes to find any threat. That is great because I don't have to manually create ten use cases, where I can create five and cover both the indexes from which I want to get a query. If I want to search a user's active directory for the kind of privileges they have, I can only create a single use case and cover both.

I don't have to search for it on different use cases manually. Splunk gives great visibility into the dependents of both indexes' coverage in one field. It gives much more context. I can get output from both indexes and correlate what has happened in the user's environment much more quickly rather than using other tools.

Compared to other tools, Splunk Enterprise Security has helped us reduce the volume of alerts and visibility of fine-tuning because it provides many different aspects. I can reduce the volume of alerts by helping users. If they have certain kinds of IPs or exceptions to the rule, I can create a macro. If they have a list of things, they can directly include another macro to make it an exception.

I can create a local file, which is a very good thing for them. They can provide insight on the local file, and I can create a specific query if they want insights on that particular local file whenever something is happening. This useful feature that Splunk provides allows users to have visibility because these are the things users might have done manually on other tools.

Since some dependencies or add-ons for visibility are already inside Splunk, it gives a lot of insight into threats. It reduces threats and gives more context to what we are trying to search for. It automatically gives us a report rather than manually checking for every other field.

Compared to other tools, Splunk Enterprise Security gives context into the raw logs, which are present in my environment, and also what are the fields I'm trying to see. It gives visibility rather than showing all the empty fields, usually presented in other tools, whenever I open any alert.

There are certain fields that are empty and others that are filled. With Splunk Enterprise Security, I can directly check which particular fields I want to see. I don't have to manually go through the whole logs page and select whatever field I'm trying to see. That is a feature in Splunk for investigation purposes.

The time taken by our analyst to resolve alerts compared to other solutions is less. Other tools provide all the available fields, and a person has to decide which field they require for a particular use case.

In Splunk, you can directly point out all the necessary fields required for a particular query you are trying to run. Then, the user can easily assess which particular field they want to investigate more. This great feature from Splunk gives an analyst less time to wait for the alert and more time to do an analysis.

The recent CrowdStrike report reported that the majority of the cyber attacks are from active directories and from the carelessness of users through phishing emails. Even though the visibility needs to be there in cyber security, organizations still usually use SIEM tools, which are much cheaper. For such cheaper tools, they have to hire many analysts, and every analyst has to be on the same page to understand the context of what is going on in their environment.

If they already have a small team, they can do this work easily in Splunk. An organization needs to understand how complex their environment is. If their environment needs a certain kind of visibility, they need to go for a tool that serves their purpose of providing insight rather than going for the cheapest solution. Also, it will be much more beneficial for their hiring purposes. Relatively fewer people will be required if they can closely monitor Splunk and create queries. If certain users have already used Splunk, it will be great for them to deploy the solution.

Splunk provides much more insight concerning the closeness of understanding everything going on in their environment. A certain group of people can get the context of what is working in their environment and how they're approaching it. This is less of a hassle in other tools where every use case will be deployed irrespective of dependency on one use case.

One field or one endpoint solution will be different from an authentication tool, and they won't be correlating as such. We will have to do that manually and search for any similar field manually. Whereas in Splunk Enterprise Security, you can deploy it at once. So, less workforce will be required for deploying, understanding, and giving context to the users working on the environment inside their organization.

Our US customer has more than 15,000 to 20,000 devices deployed since it's a hospital. They have ingestion of data from every side from where logs can be ingested. Every employee working in the environment will be interacting with the internal sources. So, we see logs in every device, including laptops, desktops, medical devices, firewalls, and mobile devices. Usually, doctors get updates and visibility on their mobile devices. These mobile devices should not be attacked as they are the ones where the user data or the patient's data is exchanged very informally.

They have deployed specifically Armis to get visibility onto their network communication, which is a very good tool. They have invested in automating the resources, creating visibility onto their environment, and blocking certain communication. They can create specific playbooks with respect to it. It has given them a much more context. The same thing is not necessarily happening with other clients because they have deployed very few devices.

So, there was no complexity in understanding the environment as such. For them, Splunk provides the same insight as any other tool. For them, it's not serving the same purpose. For them, the deployment of use cases is good and not that complex. Besides that, Splunk is not serving this client's purpose because they already have fewer resources deployed. For them, Splunk does not provide any visibility or context that could not have been filled out with any other SIEM application.

I will certainly say that Splunk Enterprise Security is a great tool if you have the context and patience to learn it. It can also serve a great purpose of understanding the environment much more clearly and easily than other tools. Users will have to compare the pros and cons if they can afford it because it will be expensive for any organization.

Overall, I rate Splunk Enterprise Security an eight out of ten.
