Splunk Enterprise Security Reviews

I use Splunk to get logs from the on-prem servers and create dashboards, alerts, and visualizations.

Splunk has helped us reduce our alert volume. It has sped up our security investigations. For example, it's easy to detect if there are multiple login failures.

It has saved us a lot of time. We previously used OpenShift to collect CPU and memory data for over 900 clusters, so we needed to log in to each cluster to get the details. Even if it only took one minute per cluster, we would spend 900 minutes doing them all, whereas Splunk can collect all the data in under a minute. 

Splunk's machine learning toolkit helps us predict things like CPU and memory usage. The user interface is excellent, and since I'm using Splunk as a power user, it's easy to create dashboards.  Splunk helps monitor multiple cloud environments. We have OpenShift. All of our VMs and servers are present in the cloud. 

Customizing our commands should be simpler. Creating custom commands in Splunk requires a long, complex process. For example, we have a command to add all the column data, but we don't have a command to get the average of the column data at the end. It would be useful to have a blank at the end to create our commands and leave the rest to others.

We have used Splunk for three and a half years.

I rate Splunk eight out of 10 for stability. 

I rate Splunk seven out of 10 for scalability. The architecture needs to be tweaked, so it might take some time to scale it. 

Setting up the architecture is somewhat difficult, but if you follow the steps laid out in the documentation perfectly, you'll understand how to do it. It's medium difficulty. 

I don't know the exact pricing, but I know that Splunk is more expensive than competing solutions.  At the same time, Splunk provides more features than others, so it's priced fairly. It's worth the money.

I rate Splunk Enterprise Security eight out of 10. SES is an excellent product. While it has some room for improvement, it's constantly adapting and trying to stay ahead of the competition. Adding commands to Splunk can be tedious. Automation, for example, helps to make the task smaller. We use Python scripts for automation. 

I implement Splunk products in customer environments. I am not an end user. I implement the product on customers' cloud stack.

I have full experience in the implementation part. I know the end-to-end configurations in Splunk. I know how to configure it, index the data, and then how to use it to get some alerts.

Splunk Enterprise Security has improved our incident response time quite a bit. What we usually do in the customer environment is to configure it with their ticket management tools. It creates alerts and pushes the alerts to the ticket management tool so that their analysts are able to view the tickets and then do an instant investigation. It provides a good solution for instant response.

Splunk Enterprise Security has complete information about the entities and the users in the organization. In the case of any alert, we do not have to manually verify the computer name and its owner name. In the alert itself, Splunk Enterprise Security populates the necessary data that we need. It is a great feature of Splunk Enterprise Security.

We have created dashboards related to critical alerts. For example, we have a dashboard for the inbound and outbound traffic flow of firewalls. We use a few other products or IT systems to monitor the CPU and memory utilization. We are also able to integrate web applications, Kubernetes, Linux systems, Windows systems, etc. We integrate whatever data sources are available.

We monitor most of the cloud environments with Splunk Enterprise Security. We have different cloud providers such as AWS, Azure, and GCP. We have separate add-ons and apps for them. It is quite easy to integrate those. Third-party developers are also able to develop their apps and publish them at Splunkbase. We can utilize them for visualization of the data that we are interested in from different sources.

We configure most of the frameworks available inside Splunk Enterprise Security such as threat intelligence, identity management, and risk management. Whenever alerts are triggered, these frameworks do the correlation and give us visualization over the dashboards, which improves the incident response time.

There is something that we can configure to reduce false positives. If any alert is triggered, it checks against various threat IOCs, such as IPs, URLs, domains, emails, file hashes, etc. If it matches any of the threats, we can take it forward.

Splunk Enterprise Security has helped speed up our security investigations.

They can also improve their capability of ingesting data from different IoT sources. It supports IoT data, but they can add some additional apps or add-ons to easily integrate the IoT devices.

I have been using Splunk Enterprise Security for the past two years.

It is a stable product as compared to other premium solutions. I do work with other premium solutions. Splunk Enterprise security is a more stable product.

It scales very easily. We can have as much data as we want. We have customers who are ingesting more than 400 TB of data per day, so it does not matter how much data you have.

We have customers that have the Splunk application deployed in a multi-cluster environment.

Their support is good, but they can have a customization team to help us with any customizations. I would rate them an eight out of ten.

Positive

This is my first tool.

We have deployed it on-prem and on the cloud. Its deployment is straightforward. Any Splunk engineer can do it.

It requires maintenance in terms of upgrades. Apart from that, it does not need any maintenance. There is a one-hour or two-hour maintenance window to upgrade the apps.

I would recommend Splunk Enterprise Security. Its frameworks make it stand out among other tools. 

It is a great solution with multiple in-built frameworks. With other solutions, there can be limitations in configuring different frameworks within the same solution.

Overall, I would rate Splunk Enterprise Security a seven out of ten.

We provide comprehensive infrastructure support and ingest mine data in three ways. The first is Agent-based where the information is sent from client machines to an agent. The second is TCP port forwarding where data is sent to Splunk through an open port. The third is the HEC token. We then use the Splunk DB Connect app to ingest data as per the client's requirements.

We are currently onboarding data from AWS to GCP. We are moving data from on-cloud to our production and deployment level environment. Additionally, the data is being added to the services on those machines. To forward the logs to Splunk, we have created a default index, which is a way of storing data in a particular way. We have created the index based on the requirements of the data storage.

Currently, we are ingesting all kinds of government security PI data. Similarly, we can ingest any kind of confidential data into Splunk using masking. This allows us to filter the data and mask sensitive information. For example, if a user account number has ten digits, we can mask out the first six digits so that only the last four digits are visible. We ingest this kind of confidential data into Splunk, and we also ingest PI data and Splunk governance data.

We are using the threat intelligence management feature. We have a separate security team, called a soft team, which is responsible for finding vulnerabilities, threats, and malware alerts in our Splunk environment. We use the threat intelligence management feature to identify any suspicious activity that may be coming from outside users. The soft team continuously monitors these alerts and creates proxy alerts to identify any potential threats.

Splunk's insider threat detection capabilities help us to easily identify threats by using Splunk queries. We have predefined Splunk Insight and are also using the one in the app, which is configured on top of Splunk machines. This allows us to quickly identify how many unknown IPs are syncing into other machines, and we can use this information to identify threats.

We use threat pathology and MITRE ATT&CK. I am currently supporting a financial institution with its infrastructure, which is split into two teams: one for complete infrastructure support, including hosting and operations, and the other for security-related matters. My team is continuously investigating new security threats, so we will take care of the onboarding process. As part of the infrastructure support team, I am responsible for handling all onboarding tasks. If I encounter any security concerns, I will escalate them to the SOC team.

We have a lot of operations using the Mission Control feature in Splunk.

Splunk helps us analyze malicious activities and detect breaches. We are using a Splunk SaaS application in a multi-class environment. To maintain high availability with zero downtime, we have maintained close to 70 indexes and 50 searches. Splunk provides us with alerts from the entire infrastructure, which helps us maintain our service. We use Splunk Mission Control to iron out any issues. For any special needs, we can go to Mission Control to verify and mitigate alerts.

Splunk Enterprise Security has helped us reduce our alert volume. Splunk currently ingests five terabytes of data, and we can set parameters to exclude rotational works and backlogs to reduce the number of alerts.

Splunk Enterprise Security has helped speed up our security investigations.

Splunk has a wide range of features that customers use to find and analyze all kinds of logs. For example, they can use SQL queries to identify vulnerabilities. Additionally, they can create dashboards to visualize and filter their data, and to create real-time alerts when thresholds are exceeded. Splunk Vision is a popular tool for data modeling and visualization and is used worldwide.

The price has room for improvement.

I have been using Splunk Enterprise Security for five years.

We are maintaining a multi-cloud environment across multiple regions, and for the last two years, Splunk Enterprise Security has maintained a 99.999 percent uptime.

We open cases on behalf of our customers with Splunk. If the technical support resolution is not up to par, we request a meeting call to work with the support team and resolve the issue for our client.

We also use the Red Hat OpenShift enterprise Kubernetes container platform. OpenShift is a more popular container tool with excellent support, but all of our OpenShift deployments are on-premises, along with production clusters around the world.

For the deployments, we scan the data to ensure that the Splunk machines can support it. If we identify anything on the machine, we ask the customer to remediate the issue by upgrading the version of Splunk. Most of our customers are using version 8.3.3.

I would rate Splunk Enterprise Security nine out of ten.

Organizations that value their security should not choose the cheapest SIEM solution. They should expect to invest in a SIEM solution that can meet their specific needs, even if it means spending more money.

Monthly patching maintenance is required. 

We gather all the security logs from all the endpoints, network appliances, and the security filter. We have set up automatic alerts that are sent to system administrators, so we have pretty much real-time alerts about anything that happens. 

Splunk Enterprise Security has definitely improved my organization. First of all, it helps with compliance. Our organization has something called scorecard requirements. It is an annual self-check checklist. Having alerts set up is one of the requirements, and secondly, we have a local administrator who gets the alerts. That makes our job a lot easier. So, we pretty much know what is going on in a real-time setting.

We are the judicial branch of the government, so we are pretty much into our private cloud. We do have a setup to monitor our private cloud but not outside our organization. If we can monitor one cloud, multiple clouds will not be hard at all. It is easy.

Splunk has absolutely reduced our mean time to resolve. Knowing on time and having firsthand information is very helpful for any organization. We are able to capture what is going on, and the visibility of it is absolutely tremendous. I cannot provide the metrics, but it has saved a lot of time.

Splunk has absolutely improved our organization’s business resilience. We have been using Splunk for the last six or seven years, and I cannot imagine a life without Splunk. 

In terms of Splunk’s ability to predict, identify, and solve problems in real-time, this is something that we will look into. We have not yet looked into machine learning, AI, and all of Splunk. Currently, we are more in the reaction mode, but we are trying to get more in the protection mode or have more proactive measures. We have not got to that point yet, but we will definitely be there.

I am not into the administrator type of setup. I am more like an advanced user. The most useful feature for me is the ability to create different kinds of alerts and set a different kind of denominator that will capture the real event. That is helpful for a power user like me.

Splunk conferences are very helpful for networking and talking to folks who have a similar situation. It would be helpful for customers if they could create some real-world cases, and we can find a case study to align with. I know that Splunk has tremendous potential. We only include a tiny piece of it. There is a lot of stuff that we need to learn. If Splunk can provide more real-time examples, that will be helpful for customers.

It has been six or seven years. 

Splunk has a reputation for being scalable. You can start small, and if your demand increases, you can scale your platform. Splunk does a good job. It allows customers to have scalability so that they can expand their capacity. I would rate it a ten out of ten in terms of scalability.

In our company, we have a Splunk consultant who is very good at providing a solution. So far, I have not had any problem that is unresolved. I would rate their support a ten out of ten. In this industry, there is good support, and there is bad support. Splunk's support is more like Cisco's support. It is pretty good.

Positive

We used something else, but I do not remember the name. Splunk is what we have been using for a long time. It is more advanced in terms of IT security. There is more scalability and the capability to do a lot of different things on multiple platforms. This is where it is more advanced than other products.

I was not in the deployment team, but I was involved in the early stage of evaluating all different kinds of products.

There are a lot of things for which you can measure a return on investment, but security is something on which it is hard to put a dollar value and measure how much return you have got. However, in terms of helping the administrator or helping the company to put security in place, Splunk does a great job. I cannot imagine a life without Splunk.

The pricing is a little bit on the higher side, but looking at what Splunk provides us, it is reasonable.

We evaluated what was on the market, and fortunately, we picked Splunk. Looking back, it was the right decision.

Splunk is moving in the right direction and providing better and more mature products. This is my fifth conference, and I see the progress. I see Splunk bringing in all new products. They are pretty much in line with the security trends. They have improved a whole lot to meet customers' needs.

I would rate Splunk Enterprise Security a ten out of ten.

We primarily use Splunk Enterprise Security for security incidents and event management. The solution is deployed in one department, but it covers multiple locations worldwide. 

With Splunk, we can monitor and manage enterprise-wide events. It provides a single console for various data sources covering the entire organization, which is critical for compliance purposes.

We can integrate Splunk Enterprise Security with other solutions to automate some security tasks, saving us some time. For example, if you detect potential malware and you want to isolate one system from the organization's network, you don't need to trigger a process. We can fully automate that. Minutes after malware is detected, the machine will be automatically quarantined from the rest of the network. 

You can integrate Splunk with third-party security automation solutions and set rules for automatic response. Splunk can monitor multiple cloud environments, but it's a little tricky if you're working with several vendors. Every cloud environment is slightly different, and some are better integrated.

The visibility into multi-cloud environments is decent. It depends on the number of sources you have, and Splunk is pretty flexible from that perspective. You can add any type of data source. The challenge is the engineering effort some of these data sources require, but others are effortless to manage.

We haven't used the insider threat capabilities yet, but it's an area that we want to explore. We have other tools for this. We use different products for threat intelligence. 

Splunk Enterprise Security could have more pre-built integrations and rules. The detection is fairly accurate, but it depends on the rules you create. Splunk's out-of-the-box configuration isn't that useful. 

If you spend time with your team creating rules specific to your environment, you can get a lot of value from Splunk. At the same time, that requires some additional effort and costs. Splunk has a few built-in integrations that are ready to go. In other cases, we need to build custom solutions, which is more difficult and costly.

I have used Splunk Enterprise Security for about three years. 

It is stable overall. 

Splunk Enterprise Security scales up pretty well. 

I rate Splunk support seven out of 10. There is a little room for improvement. We always start with junior support engineers who lack the experience to deal with complex issues, which are the only problems we ever contact support about. Our staff members can handle most minor issues. 

We typically need to escalate, and we've had an excellent experience with the higher-level engineers. Those qualified engineers are scarce, so I can imagine a situation where two big Splunk customers have significant problems simultaneously, but there aren't enough available technicians. Splunk has the right people but maybe not enough of them. The process could also be improved. 

Neutral

Deploying Splunk was relatively complex. After deployment, it requires some maintenance and management. A team of about 10-15 people is responsible for the solution. 

We deployed Splunk with an in-house team of five to 10 people and some professional support from the vendor. 

We've seen an ROI by automating Splunk Enterprise Security, but automation requires another product and license. 

Splunk Enterprise Security is quite expensive compared to some products on the market. 

The company evaluated a few tools before deciding on Splunk. I used ArcSight at a previous job. Splunk is more flexible than ArcSight, and it has various modules you can purchase to expand the functionality. You don't need to invest in a different solution because you can purchase add-ons for your existing infrastructure. 

It's modular, so you can tailor Splunk to your organization's size, structure, and specific needs. The customer can do it. You don't need to request it from a service provider. 

I rate Splunk Enterprise Security eight out of 10. My advice would be that before deploying Splunk, research some of the company's materials and make sure it meets your cybersecurity requirements. 

You may need to purchase other tools, and the solution might not do everything you want it to do out-of-the-box. Depending on your environment, you'll probably need to invest some time and money into the solution to get the results you want. 

Our primary use case is mostly for monitoring security events. We have different endpoints, like router switches. It collects a lot of data and we create reports. 

We also use Enterprise Security to send alerts out. I'm still relatively new. I mostly work for the SPL side of things.

It has been really good at consolidating a lot of data from different sources. It's really good at generating summaries. 

It's exciting to hear that SPL2 is rolling out. We look forward to using that more, especially for the data ingestion part of things. 

In the context of apps, we use a lot of search and reporting. We create many searches and reports, that quickly summarize a lot of information. That's the part that I mostly look into. That has been very valuable. I also like the dashboards and visualization features.

Its ability to provide end-to-end visibility into our environment is important. It helps a lot, especially when other users or stakeholders want that information. So being a little more transparent, but being mindful of the compliance and rules associated with that. It makes it really easy to communicate with people. They want statistics fast. The ability to quickly pull it out without a hassle is very valuable. 

We use Splunk to try to reduce the number of random alerts sent out. We're trying to consolidate a lot of functions. That has been very valuable and helpful for us.

The logging system has been a great help to us. Sometimes when we try to integrate some functions, we're not sure what errors happened. We look into the logging system, and it provides so much information. 

These optimization examples have reduced the meantime to resolve. It has been reducing cutting time.

It definitely helps our business resiliency a lot. We have a specialized cybersecurity office and on-prem technology and they really like to use Splunk. It has been addressing a lot of concerns and it is able to output the data that people are looking for. It's able to predict and identify a lot of functions.

Splunk Enterprise Security has been a great help to us in consolidating our tools. It's definitely been pulling a lot of data, especially from the network side of things. We look at it for baseline security tests. Splunk has a lot of apps and add-ons that we have been using Enterprise Security for.

I currently use Splunkbase and some of the add-ons. Integrating into our apps has been very straightforward. It would be nice if Splunk provided a little more documentation and instructions on how to upload. The steps are short, but sometimes it's not so intuitive. It would be nice if there were more user-friendly help guides.

I have been using Splunk Enterprise Security for six months. 

It has been very reliable. We haven't encountered downtime that I know of. 

Splunk works with companies that are a lot bigger than us. We're medium-sized. I have faith that we can scale. 

For technical support, I look at the online community, which has been a great help. I haven't used Splunk support directly. 

The forum is easy to use. I would rate it a nine out of ten. Sometimes the response time is slow. 

Positive

I would rate Splunk Enterprise positively. I hear from coworkers that there could be tweaks. I would give it an eight out of ten.  

In the SPL default, everything's crunched together. The formatting could be neater. When I write it in the search head, it has a lot of information in one small area. It could have a friendlier user interface. 

We use the solution to build correlation searches around insider threats and exultation of data. We also use it for DLP (data loss prevention) and to get more visibility on what's happening in our environment that could increase risk.

The solution's data aggregation has allowed our organization to unify a lot of inputs from various tools in one space and to be able to search from there.

The solution's most valuable feature is risk-based alerting, focusing on building out user risks for individuals throughout the enterprise.

It is important to our organization's security that Splunk Enterprise Security provides end-to-end visibility into our environment.

Splunk Enterprise Security's ability to find any security event across multi-cloud, on-premises, or hybrid environments is good. It's more about how you configure it and how well your company is equipped to provide and allocate resources to make the best use of the tool.

It has helped reduce our mean time to resolve.

The tool should include more real-world use case examples built out either through videos or in the community. These should not just be examples of how it can be implemented but of how previous solutions have been transitioned to new solutions and how they provide a different and better approach.

I have been using Splunk Enterprise Security for one to three years.

Splunk Enterprise Security is a very stable solution.

The solution’s scalability is based on the cost.

Splunk Enterprise Security is just a tool you can use, and then it's really up to the customer how they leverage it best.

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

Generally, we leverage it to correlate all of our threat intelligence data with all of our log events to make researching them simpler.

Splunk Enterprise Security gives us a lot more visibility into the entire enterprise and makes our analysis simpler. It streamlines the process and makes it easier to handle it.

It is very important for us that Splunk Enterprise Security provides end-to-end visibility into our environment. It saves us all the time where we used to have to go from tool to tool to tool to track down issues. Splunk Enterprise Security has tenfold reduced the amount of time it takes to investigate any one thing.

Splunk Enterprise Security simplifies being able to pivot from one data point to everything else, and it does not matter where in the pipeline that occurred because you can see it all.

It has helped improve our organization’s ability to ingest and normalize data. It has been very impressive how it is able to handle all of that for visibility and tracking things down.

Splunk Enterprise Security has not yet helped to reduce our alert volume. Our alert volume has increased at this point because we are still getting used to it, but I see how it can reduce the alert volume.

It provides us with the relevant context to help guide our investigations. The biggest part of it is that when we go through the alerts and the notable events, we are able to pivot to information from data sources that are not necessarily in Splunk, and we are able to run the automated response actions.

Splunk Enterprise Security has helped reduce our mean time to resolve. I do not have the metrics, but it is a decent amount.

Every process has been streamlined. Things for which you have to bounce between multiple tools can be done in one place, which in its nature speeds everything up and reduces the manpower.

Correlation search, in general, is valuable because it allows us to search multiple data sources easily.

The main issue that I have with it is that the field transformations sometimes overlap with those in Splunk Enterprise, and then you get permissions issues that lead to troubles.

I do not have any additional features that can be included. From what I gather, Mission Control is already included in the next release, as is a lot of the Cisco threat data.

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

It is quite good.

I have not experienced any issues with the scalability, but I do not handle the scaling, so I cannot speak to that.

I do not have to deal with them, so I do not have any information. Our administrators handle that side of things.

I did not. We acquired Splunk around about the same time I joined the cybersecurity team. 

I do not handle the administrative part. I am more of a user.

In terms of the deployment model, I believe it is technically a hybrid deployment. I am not involved in the architecture, but I know we are not exclusively cloud and we are not exclusively on-prem. We use AWS.

I know we had Splunk Professional Services for the deployment, but I was not involved.

I do not know what the cost is, but I would imagine we have seen an ROI because we are able to run our security team with fewer people than previously.

I do not know what we evaluated because I came to the company at the same time we got Splunk.

I would rate Splunk Enterprise Security an eight out of ten. It is an amazing tool that provides so much visibility and streamlines so much. The main issues I have encountered with Splunk are the difficulties in configuration and keeping everything up to date as the data sources change.
