Increases observability, cuts security operations costs, and has amazing support
Pros and Cons
  • "The consolidated overview of all the events that come in through our environment and an easy-to-access interface for all our end users are valuable."
  • "I love the solution, but I would like to see more accessibility to the machine-learning capabilities that are sprinkled around Splunk."

What is our primary use case?

Our primary use case is SOC operations. However, we do have a lot of people sprinkled around that deal specifically with data analytics.

How has it helped my organization?

Splunk Enterprise Security definitely improved our organization. It has helped out with handling our SOC operations across the enterprise. It has increased observability exponentially as we build out the solution to support enterprise operations, and we definitely hope to see it evolve in the near future as well.

We manage multiple clouds. The Spunk solution for the cloud environment is a great asset for us, especially because we are able to get full observability of our cloud platforms in a consolidated environment. In terms of integrations, Splunk has so many integrations with our different cloud service providers, which allows us to easily get that data down to our operators.

We run a global operation, so we have to have observability across the board. Splunk allows our operators to quickly gain insights into the global operation so that they can handle the day-to-day activities that they do, which includes the security analysts' work, data analysts' work, or anything along the lines of handling troubleshooting.

It has reduced our operation time, and it has cut time by more than half. 

It has improved our organization’s business resilience. It has helped with disaster recovery and continued operations in the event of disaster recovery.

It has been an extremely good asset to support day-to-day activities for operations. It is something that was required and needed for over a decade now. It is definitely a nice change of pace, and it also improves the quality of service that our operators can provide to our customers and clientele.

It has cut our costs when it comes to running security operations. I do not have the exact numbers, but it has been a significant cut, especially because we have better access to data engineering and data scientists' tool sets to cut the data cost.

What is most valuable?

The consolidated overview of all the events that come in through our environment and an easy-to-access interface for all our end users are valuable. As we get more people onboard, it is important that they are able to easily jump onto the platform and understand what they need to see in our environment. Having that quick operational capability allows us to get our observability up to speed as fast as possible.

What needs improvement?

I love the solution, but I would like to see more accessibility to the machine-learning capabilities that are sprinkled around Splunk.

For how long have I used the solution?

We have been using Splunk Enterprise Security for about a good five years.

What do I think about the stability of the solution?

It is probably one of the most resilient tools in our environment, so I really enjoy what it provides us. It definitely provides us that 24/7 accessibility to our environment.

What do I think about the scalability of the solution?

The scalability is exactly what we needed to make sure that we have observability at the global scale. For global operations, Splunk has great scaling features to make sure that it is able to handle the large volume of data that we handle.

How are customer service and support?

Splunk's support is great and amazing. The people we work with in our corporate environment are top-tier experts. They understand our environment very well, especially because they have worked in our environment before, so Splunk has done a great job in getting that type of talent to support their customers. I would rate them a ten out of ten.

How was the initial setup?

I was not involved in its deployment. I adopted it after I took this role.

What was our ROI?

We have seen a significant return on investment when it comes to Splunk, especially because of how it has allowed our operators to quickly respond to events on a day-to-day basis. It has allowed global observability.

There has definitely been a time to value. It comes down to having operators have access to such a unified platform.

What's my experience with pricing, setup cost, and licensing?

From what I have seen so far, Splunk has multiple cost models. The one that we are using is pretty good when it comes to ingesting data into the environment. It has worked out pretty well.

Which other solutions did I evaluate?

We have evaluated other solutions, and Splunk definitely comes out as one of the top competitors due to its interoperability with a lot of data sources that are sprinkled around in our environment. This interoperability is a key piece because we have such a diverse asset environment.

What other advice do I have?

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

The biggest value I get from Splunk conferences is being able to interact with my peers throughout our organization. I get an idea of what they are doing to make sure that we are on the same page and that we are able to cohesively build our security operations.

The analytical features helped us reduce our alert volume by 30 to 40 percent
Pros and Cons
  • "I like Splunk's data aggregation and search capabilities."
  • "Splunk could add more ways to manage archiving and storage. There isn't a web interface. You can do this on the SaaS version, but the on-premise platform doesn't have this option. It has other things but no option for remote NAS. I would like to have a personal web interface where I can specify how long logs should be stored. To have this readily available on the web, you need to adjust some settings on the backend. That is tricky."

What is our primary use case?

Splunk Enterprise Security is a SIEM solution we use for security compliance and threat detection. 

How has it helped my organization?

Splunk helped us fulfill our requirements for security compliance and auditing. It also protects us from attacks. We can quickly notify our customers if they are facing any attack or breach. 

The solution's analytical features helped us reduce our alert volume by 30 to 40 percent. Splunk significantly speeds up our security investigations. 

What is most valuable?

I like Splunk's data aggregation and search capabilities. The insider threat detection features are handy, and Splunk's user behavior analytics are solid. It's one of the best tools for UBA. It covers everything. 

Splunk's Threat Intelligence Management draws from 10 to 15 open-source sites in real-time, enabling us to correlate our data with the IOCs. It helps us detect zero-day attacks. Splunk's threat topology and MITRE ATT&CK framework cover everything, including endpoints and application security from Layer 3 to Layer 7. Most queries are available out of the box. 

It's a fantastic tool for monitoring your environment. It allows you to do some granular analysis and see which assets are part of an attack. When breaches occur, you can quickly search your entire environment. It speeds up our threat-hunting process. 

What needs improvement?

Splunk could add more ways to manage archiving and storage. There isn't a web interface. You can do this on the SaaS version, but the on-premise platform doesn't have this option. It has other things but no option for remote NAS. I would like to have a personal web interface where I can specify how long logs should be stored. To have this readily available on the web, you need to adjust some settings on the backend. That is tricky. 

For how long have I used the solution?

I have used Splunk Enterprise Security for four years. 

What do I think about the stability of the solution?

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

What do I think about the scalability of the solution?

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

How are customer service and support?

I rate Splunk support eight out of 10. 

How would you rate customer service and support?

Positive

How was the initial setup?

Deploying Splunk is straightforward, but it requires some preparation. After you get your platform ready, the onboarding is easy. It isn't rocket science. Configuring visualization is also simple. It doesn't require much maintenance on our end because we have an SLA. 

What's my experience with pricing, setup cost, and licensing?

I work on the technical side, so I don't know precise figures. However, I know that Splunk is a premium product, so it's somewhat costly. Still, you get a lot of unique features for the money. 

You can choose the cheapest solution, but that will only help you achieve compliance in the near term. However, over time, you will begin to realize that there are so many security gaps that your team can't address. You need a solution like Splunk to maintain long-term security compliance. 

What other advice do I have?

I rate Splunk Enterprise Security 10 out of 10. My advice to Splunk users is to keep it simple. You don't need to complicate things or bring in AI and ML. Focus on the fundamentals like data onboarding and extraction, parsing, visualization, etc. Keep your dashboard simple, so it's easy for the end-user to understand. 

Which deployment model are you using for this solution?

Enables us to integrate the solution with other products to automate tasks, saving us time
Pros and Cons
  • "You can integrate Splunk with third-party security automation solutions and set rules for automatic response."
  • "Splunk ES 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."

What is our primary use case?

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. 

How has it helped my organization?

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. 

What is most valuable?

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. 

What needs improvement?

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.

For how long have I used the solution?

I have used Splunk Enterprise Security for about three years. 

What do I think about the stability of the solution?

It is stable overall. 

What do I think about the scalability of the solution?

Splunk Enterprise Security scales up pretty well. 

How are customer service and support?

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. 

How would you rate customer service and support?

Neutral

How was the initial setup?

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. 

What about the implementation team?

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

What was our ROI?

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

What's my experience with pricing, setup cost, and licensing?

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

Which other solutions did I evaluate?

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. 

What other advice do I have?

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.

The solution is user-friendly, and we can easily customize the monitoring script
Pros and Cons
  • "Splunk is user-friendly. We can easily customize the monitoring script."
  • "Splunk isn't appropriate for smaller companies. It's too expensive."

What is our primary use case?

We use Splunk to monitor unusual user behaviors. For example, if any user onboards from a different domain, it will trigger an alert. We also get alerts and high traffic when the ADI server is down. Splunk will monitor that behavior or when users make repeated wrong login attempts.

My full-time job is managing the IAM product. Splunk is one of our security monitoring tools. Most of my work is on IAM tools like CyberArk and SailPoint, etc. 

How has it helped my organization?

Splunk manages all of our security and maintains a hundred percent availability. It improves business while securing the entire cloud environment. In terms of business, we don't need manual monitoring. It automatically monitors and notifies an administrator, so we can easily track and identify the particular issue. It saves our employees' time, and we can manage the environment without any impact on business service.

In the UK, hackers use automated software to make repeated login attempts. Splunk immediately identified these attempts and notified the admins, so the red team suddenly took action to block them.

It's nonstop monitoring that isn't affected by business hours. You don't need a manual administrator. Splunk will monitor everything, and a single administrator can monitor the alerts. Splunk will notify us if any unusual behavior happens, allowing us to take immediate action. There's no need for any further investigation and log analysis. It provides the exact result, what happened, and where it happened. 

Splunk helps us reduce alert volume. Whenever the same type of attack occurs repeatedly, we can change the environment and improve the security so the attack won't repeat. 

It speeds up our investigations through automation. Investigating manually takes a long time, and we sometimes cannot identify the exact issue. Splunk monitors the data and events, so we configured a range. If it triggers that area, it will provide the exact result. We can immediately identify and fix it. There's no need to investigate. It reduces the mean time to resolve by 80 percent. 

What is most valuable?

Splunk is user-friendly. We can easily customize the monitoring script. We support a multi-cloud environment covering Windows Server, AWS, and Google Cloud. We also use ForgeRock to monitor Linux machines. It sends us alerts when the disk size gets full. When an employee logs in from a different region, it triggers an alert. 

What needs improvement?

Splunk isn't appropriate for smaller companies. It's too expensive.

For how long have I used the solution?

I have used Splunk for two years.

What do I think about the stability of the solution?

Splunk is a highly stable product. 

How are customer service and support?

I rate Splunk nine out of 10. When we have any questions, we raise a ticket and they respond in two or three hours. 

How would you rate customer service and support?

Positive

How was the initial setup?

Splunk provides the tenant, and we can directly integrate it into the cloud URL. For the hosting, we can deploy it to the EC2 instance. Splunk is integrated with Cypress, CyberArk, and Fastdesk. Splunk also supports SAML integration. Splunk is a SAML application, so we can use SAML protocol to enable it. 

What other advice do I have?

I rate Splunk Enterprise Security nine out of 10. 

Which deployment model are you using for this solution?

Public Cloud

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

Brings all of the components necessary to identify, analyze, and respond together
Pros and Cons
  • "The most valuable feature is that it brings all of the components necessary to identify, analyze, and respond together."
  • "Splunk is such a large product. Allowing it to be more easily used by people who have not had a lot of training on it would be an improvement."

What is our primary use case?

Our primary use cases are for detection and remediation.

How has it helped my organization?

The benefits we've seen from Splunk is that we can promote it to our customers. The second benefit is that it works. It does what it's purported to do, and the support is more than adequate. 

What is most valuable?

The most valuable feature is that it brings all of the components necessary to identify, analyze, and respond together.

It's pretty important that Splunk provides end-to-end visibility into your environment. As in any product that one purchases to fulfill a function, we want to recognize where it came in, who it affected, and what the challenges are that need to be met in order to resolve something, both immediately and also to make sure that it doesn't replicate in the future. Splunk does a good job of being able to do the former half. Dealing with issues requires tier-three support and above and it takes time. You can work through it with the help of your vendor team.

I would rate them an eight out of ten. It's not so much the problem of the application itself, although there are always improvements that can be done. There are a lot of moving parts that need to be added in and if you don't have the information that you need, especially within identity and inventory, then that can be an added challenge when you have to start making imprints based on what you do know.

Splunk Enterprise Security provides us with the relevant context to help guide our investigations. There are a number of different standards that can be presented, which is beneficial. Some customers like to have the information that they receive in one format. The driving factor is that when you work with federal customers, some of them want it in one format. The response will be in one format as opposed to another. 

Splunk has helped to improve my company's business resilience. It's an active component in ensuring that we are vigilant against intrusion and detecting it.

What needs improvement?

Splunk is such a large product. Allowing it to be more easily used by people who have not had a lot of training on it would be an improvement. That's something that they're accomplishing with their current version, although I haven't had an opportunity to learn much about it. With AI capabilities coming on board, a lot of that will alleviate the minutiae that people need to know in order to resolve problems as they come up.

Splunk's ability to predict, identify, and solve problems in real-time is a work in progress.

For how long have I used the solution?

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

What do I think about the stability of the solution?

Aside from the fact that it can be a resource hog, I'm satisfied with the stability. I don't have too many problems except for a few occasions when we have a threat intelligence file blow up a drive because there's not enough room. It might be because a complete configuration has not been implemented. 

What do I think about the scalability of the solution?

I like the fact that it can be tweaked, but a lot of the various configurations for how long data is held or how long particular components of investigation are held. 

How are customer service and support?

I encourage users to use the vendor management team and cultivate a relationship with them. I have worked with companies who had support that I would rate 11 out of 10. I would rate Splunk an eight out of ten because as any large growing company, they have challenges with keeping the talent necessary, who are not only educated to evaluate a problem and pass it on or solve it themselves.

How would you rate customer service and support?

Positive

How was the initial setup?

The largest challenge with the setup is that it has so many different components. The environment that we're in is a multi-tenant. Enterprise Security with all of its components is huge. If you're using something like a deployment server you can't break it up. It makes it rather unwieldy. I'm sure that there are workarounds that have not been implemented in-house.

What was our ROI?

Splunk provides more than the people who pay for it realize. I had a few exercises in presenting ROI and benefit-cost analysis and I have been able to demonstrate where it has performed superior to other options.

What's my experience with pricing, setup cost, and licensing?

I was deeply distressed when they went away from their perpetual license.

Which other solutions did I evaluate?

We evaluated Splunk's typical competitors. We went with Splunk because Splunk has the underlying capability of not only ingesting anything and storing it using their bloom filters and whatnot in order so that you can do sparse and large searches relatively quickly. It also has a wonderful presentation layer, which can basically plug into many other systems. I find Splunk to be a veritable Swiss Grey knife of capabilities.

What other advice do I have?

I would rate Splunk Enterprise Security an eight out of ten because there's always room for improvement and because it can be difficult to learn.

Which deployment model are you using for this solution?

Offers integration with other risk-based solutions
Pros and Cons
  • "If properly built, I'm very impressed with the stability of Splunk ES."
  • "In terms of training. I find that some things about Splunk aren't well-explained. I see features and then go to the website but don't find good explanations."

What is our primary use case?

The primary use case is computer network defense.

How has it helped my organization?

It is very important that Splunk ES provides end-to-end visibility in our environment. Part of the solution is bringing the user closer to the resolution.

The integration with other risk-based solutions, such as the risk matrix applications included with Splunk, is helpful. It helps us identify the risks without having to delve into other resources.

Splunk helped improve our company's ability to ingest and normalize data. That's the primary use of Splunk Enterprise or Core. For ingestion, we've been using Splunk Enterprise for about six or seven years before we had ES. So, that was the primary reason we got it.

In terms of the risk-based part, Splunk improved our ability to ingest and normalize data. Initially, we used Splunk Enterprise Core for aggregation and correlation. We didn't have the risk-based reporting.

I'm very impressed with Splunk's ability to identify and solve problems in real time. And I look forward to the new version improving the product.

We've been able to discover things we didn't see before. So, there's more that we discover now.

Splunk ES provides us with the relevant context to help guide our investigation. It goes back to the time to resolution. We have to do much less investigation because it's already built-in alerting. 

What is most valuable?

Risk-based reporting and anomaly detection are valuable features.

The biggest advantage is the reduced time to resolution. Before, it took us up to days to resolve issues, and with Splunk, we've been able to move that down to hours or even minutes in some cases.

What needs improvement?

I was just at the conference, and they spoke about and demoed a new version of Splunk. It looked like some pain points are resolved in the new solution, such as not having to go to so many different panels. Like to streamline or improve the UI. 

In terms of training. I find that some things about Splunk aren't well-explained. I see features and then go to the website but don't find good explanations. However, I can always call support and get help.

For how long have I used the solution?

We purchased ES four years ago.

What do I think about the stability of the solution?

If properly built, I'm very impressed with the stability of Splunk ES. We initially stood it up on a single server, and to make it more robust, we had to break out of that single server concept to make it more resilient. 

What do I think about the scalability of the solution?

The scalability is very good. That comes from our experience of having to scale out, and Splunk's documentation on scaling up is very good.

How are customer service and support?

Every time we've used Splunk support, it's been very good. We don't have any in-house Splunk engineers, but headquarters has some they can send to assist us, so I can call on them. It's a very good support chain.

If there is some room for improvement, it is in terms of training. I find that some things about Splunk aren't well-explained. I see features and then go to the website but don't find good explanations. However, I can always call support and get help.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

My company is very impressed with Splunk. We've used several SIEMs before, and Splunk has been the most efficient one.

There was one called Intelotactic, and another was called Secureworks. I believe both of those are gone now.

Initially, with Splunk, we had a steep learning curve. It went from a fairly low ingestion point to figuring out how much data we needed to get to a certain level. Even when we got to a level we were happy with; we found that we were ingesting a lot of noise in the data. We had to figure out ways to reduce that noise.

How was the initial setup?

We bought the maintenance along with Splunk ES and used Splunk engineers to assist us in the setup. It was a very good process. It worked out very well for us.

The knowledge of the individual sent to us was impressive.

Deployment model: Ours is all on-prem currently, but we are headed towards a cloud solution.

What other advice do I have?

I would rate it a nine out of ten.

Helped improve our organization’s ability to ingest and normalize data but should work better out of the box
Pros and Cons
  • "Splunk Enterprise Security helped improve our organization’s ability to ingest and normalize data."
  • "In the next release, they should include machine learning-based rules that would streamline the process of finding anomalies."

What is our primary use case?

Our primary use case is to find brute-force attempts on our systems. 

How has it helped my organization?

We use it for security purposes, to find malicious activity, and to find misusage of our business platform.

The main benefits we have from Splunk Enterprise Security are the alerts with which we can manage the searches and the notables which can be good for documentation.

What is most valuable?

Identity management is the most valuable feature. 

Its ability to find any security event across any environment is useful if you use the risk parameter. If it can correlate with an identity or an asset, then correlations between such events are up to the analyst. 

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

Splunk helped to reduce our alert volume by 53%. We work based on an on-call process. The analyst who is on call can use Enterprise Security to see what alerts they have and work from there.

If you load it correctly, Splunk will provide us with the relevant context to help guide our investigations. It made it easier. 

Splunk Enterprise Security helped improve our organization's business resilience.

In terms of its ability to create, identify, and solve problems in real-time, if the problem arises, we can go and look at Splunk, but if it's happening in real time and no one reports the issue, then it doesn't work in real time. 

It helps consolidate networking, security, and IT observability tools but it doesn't have such a big impact on our company. 

What needs improvement?

It should work better out of the box and have better use cases that would not require my intervention. For example, if I install an antivirus and endpoint protection on my computer, I don't need to do much. But to get any value from Splunk, I need to work hard on it. 

In the next release, they should include machine learning-based rules that would streamline the process of finding anomalies.

For real-time detection, I would not say that Splunk is the best. If you experience a problem and go to Splunk to look at the dashboard, then it's in real-time. Because of the way Splunk works, I wouldn't get an alert in real-time. 

For how long have I used the solution?

I have been using Splunk Enterprise Security for five years. 

What do I think about the stability of the solution?

On newer servers, it can be stable. On our servers, it can take a while. We need to re-enter when we press selections. 

What do I think about the scalability of the solution?

It is scalable. You can add more servers and analysts. 

How are customer service and support?

Support depends on the issue. Sometimes they help but most of the time, I have to solve the issue on my own. 

I would rate support a six out of ten. Usually, it can take time until I get to someone who can help. The diagnostics aren't always accurate. I once had an issue where they replaced a certificate that we weren't using, so it didn't solve the problem. It can take a few iterations to solve the problem.

How would you rate customer service and support?

Neutral

How was the initial setup?

The deployment is fine for me, but it is not really straightforward. I would suggest simplifying the process. For example, the whole certificate part is not secured by default. I would recommend fixing that.

What about the implementation team?

We used EMET Computing for the integration. They are fine. 

What was our ROI?

We do see ROI. We can deduce the ROI from finding the damage that misusing our business platform is causing. 

What's my experience with pricing, setup cost, and licensing?

I think that the price can be too high sometimes, especially for the cloud. We get a lot of logs that are meaningless. For example, if we are using a firewall, we get a message for every session or packet. A lot of those connections are the same. We pay a lot of money on the license and on logs that are the same. If there was a way to aggregate them, the cost of the license would be reduced.

What other advice do I have?

I would rate Splunk Enterprise Security a six out of ten. It is useful but it doesn't add that much value on top of standard Splunk. Because of our use cases and environment, we don't use all of the features it has. Nevertheless, the value it provides isn't so different from Splunk Core.

The incident review functionality gives a good overview of security incidents
Pros and Cons
  • "The solution's most valuable feature is the incident review, which gives a good overview of our security incidents."
  • "You can run a script from an event, but it needs many clicks to run that integration, which could be made easier."

What is our primary use case?

We develop use cases for Splunk Enterprise Security all the time. I mostly work with the SOAR platform to ingest those use cases.

How has it helped my organization?

Splunk Enterprise Security helps our organization because we use it daily to solve our security use cases. We have incidents every day.

What is most valuable?

The most valuable feature is the incident review, which gives a good overview of our security incidents. I also like the solution's search functionality, which makes it easy to find things.

Splunk Enterprise Security generates our alerts, and we would have to refine the searches if we want to reduce them.

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

Splunk Enterprise Security has helped reduce our mean time to resolve and helped improve our organization’s business resilience.

What needs improvement?

The incident review could definitely be improved in many ways. It should be easier to run integrations from it. You can run a script from an event, but it needs many clicks to run that integration, which could be made easier.

For how long have I used the solution?

I have been using Splunk Enterprise Security for five years.

What do I think about the stability of the solution?

The solution’s stability is very good, and we haven’t had any stability issues with Splunk Enterprise Security.

What do I think about the scalability of the solution?

The solution’s scalability could have been better.

How are customer service and support?

The solution's technical support is very good, and I'm very happy with the support.

How was the initial setup?

The solution’s initial setup is easy.

What other advice do I have?

Overall, I rate the solution an eight out of ten.

Provides end-to-end visibility and reduces the investigation time tenfold
Pros and Cons
  • "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."

What is our primary use case?

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

How has it helped my organization?

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.

What is most valuable?

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

What needs improvement?

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.

For how long have I used the solution?

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

What do I think about the stability of the solution?

It is quite good.

What do I think about the scalability of the solution?

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

How are customer service and support?

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

Which solution did I use previously and why did I switch?

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

How was the initial setup?

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.

What about the implementation team?

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

What was our ROI?

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.

Which other solutions did I evaluate?

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

What other advice do I have?

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.

Serves as our SIEM, providing security alerts and operational alerts
Pros and Cons
  • "The solution's most valuable feature is the criticality of alerts."
  • "The solution's automation could be improved."

What is our primary use case?

We usually use the solution for the same functionality, which includes setting up alerting and making notables. We also use it for the workflow from ingestion, alerting, and response.

How has it helped my organization?

Splunk Enterprise Security serves as our SIEM, providing security alerts, operational alerts, and even some logging that we probably need to check in on from time to time. It basically serves as an alerting platform for our enterprise.

What is most valuable?

The solution's most valuable feature is the criticality of alerts. Some alerts can be noise, and others will be more high-level and warrant a higher-level response than others.

What needs improvement?

The solution's automation could be improved. It would be better if we could automate ingesting and alerting for low-level events.

For how long have I used the solution?

I have been using Splunk Enterprise Security for seven to ten years.

What do I think about the stability of the solution?

I rate the solution’s stability a nine out of ten.

How are customer service and support?

For the times I've had to set up incidents from critical to lower ones, the technical support team has been fairly responsive. Sometimes, the support team has had a two to three-hour turnaround time for critical incidents. Usually, you would like to get to someone sooner rather than later for critical incidents.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

I've previously used other SIEM tools like ArcSight, QRadar, and Elastic Security.

What was our ROI?

We have seen a return on investment with the solution.

What other advice do I have?

The solution helps us see what's actually happening in our environment. Some things we might not expect at times, and others we do expect. The tool helps us respond based on what we see from our logs. I've seen and thoroughly liked some AI, automation, and single-pane-of-glass updates coming to the solution.

It is very important to our organization that Splunk Enterprise Security provides end-to-end visibility into our environment. You can't respond to what you can't see was ingested. So, the visibility provided by the tool into our logs and alerting environment is critical.

From an ingestion point of view, the solution alerts you to what you'd tell it to. It's pretty agnostic log-wise.

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

It has helped reduce our alert volume. You're getting the same alerts. You can see what's noise, what's actionable, and what's not as actionable.

Splunk Enterprise Security provides us with the relevant context to help guide our investigations. We see what's coming into the environment, including specific logs that we wouldn't expect as much. All of that gets filtered into alert data, potentially operational data, and sometimes even billing data, so we can adjust and move forward with that in the environment.

Splunk Enterprise Security helped reduce our mean time to resolve by somewhere between 20% to 35%.

Splunk Enterprise Security has helped improve our organization's business resilience for some ingestion purposes.

The unified platform helps consolidate networking, security, and IT observability tools. Splunk is pretty log-agnostic. All of your logs, tools, and sometimes even dashboards can get ingested into one specific tool. That way, you have a single platform where you can view all those logs and respond based on that data.

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

Which deployment model are you using for this solution?

Public Cloud

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
