Splunk Enterprise Security Reviews

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.

Our use cases are mostly for security and detection, basic use cases. It's always been a security use case. We never used it for observability or ITSI. 

Our analysts use it a lot.

I like that it's a review panel, you can see all of your alerts. Another valuable feature is that it integrates with other apps like UBA and SOAR. 

I also like the guided alert creation. The guided alert creation is useful, especially for new people who don't know CPL. 

It's a premium app, it's easy to use and intuitive. 

Enterprise Security has one pane of glass for all of our alerts. We still use the Enterprise Security page where we keep track of everything. 

It's very important to us that Splunk offers end-to-end visibility into our environment. It has the ability to identify any security events or if data is reingested, we'll get an alert for that. End-to-end visibility is very important for a mature security program.  

Splunk helped to ingest and normalize data. Anytime that we put data in, we always normalize the SIEM model. ES runs off of that so it helps us to dot our I's and cross our T's. It helps us to use our data effectively.

It has tools to reduce our alert volume. We get a lot of alerts. It's more of a tuning thing than anything that the app can help with. 

It provides us with the relevant context to help guide our investigations. It's really useful in that aspect. 

It hasn't reduced our MTTR. SOAR would do that. It has helped our mean time to detect. 

It has increased our business resilience. It's a top-of-the-line SIEM security product. It's the best tool for our security analysts which helps them do their job better. That then protects our company from adversary actors. 

I have been using Splunk Enterprise Security for about five years. 

I've never had too many issues with the stability. Years ago we had indexes crash but that was more on us. We didn't understand how to properly size Splunk. If you work within the required parameters, it's stable. 

Their support is great. I've never had any issues with them.

Positive

The setup was pretty straightforward unless you add a search head cluster. Then it becomes a lot more complicated very fast. Other than that, it's not too bad. It's pretty simple and intuitive. I've done it before and it's not difficult especially if you have the docs to help you. 

I can't speak to the dollar amount but we see ROI in the way that it helps the analysts to better do their work. It helps keep track of things and having one pane of glass for all things data. 

I would rate Splunk Enterprise Security a nine out of ten. It's a top-of-the-line product. It allows analysts to do their jobs better. It's a single pane of glass. It's a fantastic tool that we couldn't do our work without. 

We use Splunk Enterprise Security for a lot of use cases. We use the predefined use cases and dashboards for AWS, notable events, endpoint detection network, and audit notable events.

The most valuable function is the notable events. When I joined the team, I asked them what they could currently see, and they said nothing. I was pretty shocked. I know that they were using Enterprise Security or at least they had purchased it. I told them that there are several dashboards within Splunk that we can leverage. There is also notable events where we can see potential incidents or potential alerts about the infrastructure and the network itself. 

The dashboards give us numbers for malware infection. So long as those dashboards are actionable, they help the SOC team a lot.

It's important to respond to incidents in a timely manner. Having end-to-end visibility across the board equips the team to make sure that whatever incident happens, it has a very minimum impact on the business. It also allows us to fix things that need to be fixed immediately. That's the asset of having end-to-end visibility across the board.

Enterprise Security really helps us normalize our data because it comes with predefined dashboards, so we only need to ingest the logs and Splunk will do the work to display what we need to see on a day-to-day basis.

When we started using Splunk, we had tons of false positives. We reduced our alerts by 90%. Most of our alerts now are actionable.

I would like to have fraud detection features. Fraud is within the same turf as with security operations. Fraud and cybersecurity work hand in hand. I would like to have detection capabilities, or at least dashboards in Enterprise Security for fraud. 

There's already a fraud offering from Splunk for fraud use cases but it's different. I need to get professional services for me to get that feature. It would be much more cost-efficient for customers if all those dashboards could be readily available within ES.

I have been using Splunk Enterprise Security since I joined my company in 2019, so it's been roughly five years.

Cisco just acquired Splunk so I expect the stability to still be the same since Cisco is established. 

I would rate support a nine out of ten because there's always room for improvement. 

Positive

I would rate Splunk Enterprise Security an eight out of ten. To make it a perfect ten, I would like to see them implement the fraud detection features. 

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.

We wanted the solution to enhance the SOC ability. We were having trouble with some of our data being SIEM-compliant.

We hope the solution meets some SOC-like abilities.

Splunk Enterprise Security gives us a single pane of glass so that we can use just one tool instead of having to use different solutions.

It is pretty important to our organization that Splunk Enterprise Security provides end-to-end visibility into our environment, and it gets more important every year.

Splunk Enterprise Security has helped improve our organization’s ability to ingest and normalize data.

It has helped us reduce our alert volume.

Splunk's unified platform helps consolidate networking, security, and IT observability tools. It gives us a single pane of glass, so instead of having to go to different tools, we just go to one tool.

It is deployed as an app on its own server.

It'd be really nice if Splunk Enterprise Security had a better and solid configuration guide.

I have been using Splunk Enterprise Security for roughly one year.

Splunk Enterprise Security is a very stable solution, and we haven't had many issues in five years.

The solution’s technical support team is very knowledgeable.

Positive

It was a little difficult for us to set up the solution mainly because some of our data sources were not SIEM-compliant.

We did engage with Splunk professional services, but it still didn't work. Although our experience with them was good, the tool was still not set up correctly.

We have seen a return on investment with Splunk Enterprise Security.

My experience with the solution's setup cost, pricing, and licensing was really good.

Overall, I rate the solution a seven out of ten.

We use Splunk Enterprise Security to analyze log data for log monitoring, creating use cases, onboarding, and incident response.

We wanted a single security tool that could immediately identify notable events that could be reported as security breaches, and then enable us to take intelligent action without having to purchase additional security tools.

We have two customers with hybrid cloud solutions. Neither customer is fully cloud-based. Our implementation is based on the customer's requirements, such as compliance, data ownership, and administration. We plan the implementation of Splunk cloud or hybrid models based on these requirements. We discuss the benefits and solutions with the customer to ensure that we are not breaching any compliance policies and that we are selecting the right model for their needs. Because we have multiple customers, we must also consider how to manage this process effectively.

We use multiple cloud environments for our clients, including AWS, Azure, GCP, and private cloud. We can easily integrate Splunk Enterprise Security and segregate the logs based on the type of index we create for each customer. When we create different indexes, we can segregate the types of logs based on the device type. This makes it easy to separate logs from different universal providers, different machines, and specific types of indexes dedicated to particular customers or groups.

We use threat topology and MITRE ATT&CK to create and integrate use cases for network framework detection and visualization in Splunk. Splunk helps us segregate and integrate use cases based on different threat detections and provides a complete dashboard view of how use cases match with detected threats.

When discussing MITRE ATT&CK and topology, we sometimes encounter use cases where we must ensure the logic is properly implemented to detect the threat and trigger the alert. This is because log access may involve specific teams and their associated MITRE ATT&CK tactics and techniques. We must be very specific about the information we are observing in order to derive the correct information and framework topology.

Splunk is one of the easiest solutions for analyzing malicious activities and detecting breaches. It is flexible enough to work with small teams, and it provides a broad view of the data, allowing us to segregate and fine-tune the analysis based on the customer's requirements.

Splunk Enterprise Security can help us detect threats faster when it is properly configured. We have implemented over 400 use cases for specific types of malware and other threat detection. In over 70 percent of environments, Splunk is able to detect threats faster than other solutions.

It has helped our organization improve by integrating with cloud providers. Splunk enables us to blacklist specific data types and ranges to reduce our losses, based on our requirements.

We have reduced our alert volume by around 50 percent with Splunk. When we first started creating and using Splunk use cases, we received around 700 alerts. Splunk can merge different sources of use cases into one to identify false positives, which has been very helpful for us.

Splunk has helped speed up our security investigations by almost 70 percent. We have a dedicated incident response team. They use the Splunk incident reports to help with their investigations. 

Splunk Enterprise Security comes with 300 pre-deployed use cases that can be easily customized to meet the specific needs of our organization, without the need to purchase additional tools.

We can easily identify the number of security devices and users that are authenticated on the network and present the information to the executive team.

Splunk can improve its third-party device application plugins.

I have been using Splunk Enterprise Security for five years.

Splunk Enterprise Security is stable.

Splunk Enterprise Security is scalable.

The Splunk technical support is good but their call times differ.

Positive

I previously used IBM Security QRadar, Azure Sentinel, and McAfee Network Security Platform. Splunk Enterprise Security is designed for multiple platforms and is easier to implement.

Splunk is much faster when used correctly and has many tools. With the exception of Sentinel, the other solutions do not have many tools. With Sentinel, we have to define the indexes and all those things, such as the aggregation of logs. It is easy to do searches in Splunk, even in a large environment. I find Splunk to be more efficient than the other solutions I have used in the past.

The initial deployment is straightforward. We install the solution and define the roles of each server and the data it will store. The deployment in our test environment took 13 hours.

We have seen a return on our investment in Splunk. The variety of options that Splunk provides is a great selling point for our customers.

While Splunk is more expensive than other solutions, we would still choose it because of its capabilities. Splunk is a leader in the field and provides a wider range of data and security features than other SIEM solutions.

I would recommend Splunk over any of the less expensive SIEM products. I recommend the license-based solution over the user-based solution that Splunk offers. If I had to recommend any other SIEM other than Splunk, it would be Microsoft Sentinel.

I would rate Splunk Enterprise Security seven out of ten.

The threat detection capabilities that we get by default are very basic. However, if we want to implement the most effective threat protection on the internet, we need to purchase a relevant solution for intelligent threat protection. This will provide us with more feeds for enterprise security and help us to integrate data by matching the data to the target and to the security with our Splunk.

We have 60 percent of our customers using Splunk Enterprise Security in their environments.

Splunk maintenance is required for updates. 

Splunk provides a centralized monitoring platform, eliminating the need to switch between different platforms to monitor security. Splunk provides a clear view of different security losses and incidents, and we can onboard any number of devices as needed. We can monitor our entire environment from one place, requiring only one team to monitor it. Splunk adds a lot of value currently.

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. 

Our use cases are for creating security analytics for our SOC team.

Splunk Enterprise Security is one of the Splunk tools we use to mature our security posture. We use it to be on top of potential threats to the organization.

The benefits include the easy integration with other Splunk tools including Splunk UEBA, Splunk ITSI, and Splunk Core. The ease of integration and the organization's experience and familiarity with searching and passing logs through Splunk are the main benefits.

Apart from the legal and compliance requirements for the bank, it's important that the bank is ahead of bad actors to be able to proactively detect and prevent threats to the organization. At the end of the day, the goal is to protect the organization, the stakeholders, shareholders, the bank's reputation, and the users and customers of the bank.

The Splunk incident response dashboard is pretty useful because it helps first responders triage incidents and properly escalate when necessary.

We find Splunk very useful on the enterprise level to detect and prevent security threats.

Splunk Enterprise Security has definitely helped improve our organization's ability to ingest and normalize data. We have many log sources and over ninety thousand staff. We have endpoints, servers, Syslog Data, and BYOT data. Splunk has been instrumental in maturing the security posture of the organization.

Splunk does a pretty good job at identifying threats in real-time. 

It provides us with the relevant context to help guide our investigations. During onboarding, once the log sources are properly onboarded based on Splunk's recommendation for SIEM compliance, we found real value in being able to aggregate different types of data and load them properly so that we can then pass on and access them very easily. 

It has improved my organization's business resilience. We've been able to mature our security program and posture over the years.

The ability to see everything from a single tool is very helpful. From the context of communication with our executives, being able to show them a unified dashboard to see the security posture has been very useful. For example, our executives can see the security posture or position of all of the branches of the bank from a single dashboard. Dashboards like that give them peace of mind to have that kind of visibility to know the state of things. Splunk is very instrumental in that. 

The incident response dashboard could be more user-friendly.

In the next release, I would like to see the integration of Splunk Enterprise Security with Splunk UEBA. That's a big one. We've spoken with the engineers working on a new UEBA integration with Splunk but right now Splunk UEBA is a separate setup entirely.

I have been using Splunk Enterprise Security for three years.

Splunk Cloud has its advantages. The company might be moving in that direction because you don't worry about infrastructure. But being on-prem part of what we worry about is the underlying infrastructure of Splunk, which is directly relevant to the stability. The resources used for search and load are tied to the infrastructure behind it. It's been stable. 

We've been able to scale rapidly to meet our needs. Splunk Cloud could be advantageous because it's a platform and it will cut out the worry and the need to manage infrastructure on your own. 

I work more with Splunk UBA. My experience with my rep has been good. 

I would rate support an eight out of ten only because everything has room for improvement.

Positive

It's an on-prem deployment. I have more experience setting Splunk up in a Linux environment. It's been a good experience.

I would rate Splunk Enterprise Security a seven out of ten because there's room for improvement. Splunk always positions itself as a market leader. This would involve understanding your competition, seeing their products, and seeing how you can improve to meet their customers' needs. 

From my experience, Splunk has done a good job at that because we have customer success reps who are concerned about how Splunk is meeting our needs. Splunk can definitely do better which is why I'm giving it a seven.
