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 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.

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.

Which deployment model are you using for this solution?

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

Risk-based alerting significantly reduces the alert volume and speeds up the investigation
Pros and Cons
  • "I am enjoying our implementation of risk-based alerting. That has helped very much with cutting out a lot of the noise that we have. It has reduced our alert volume significantly. There is about an 80% reduction."
  • "I do not like the pricing model. It is expensive."

What is our primary use case?

We use it for alerting. It also helps our analysts triage.

How has it helped my organization?

It is our bread and butter and our day-to-day tool for the SOC. Besides alerting, just being able to do research and look through various logs to gather context around the alerts has been super valuable.

It is critical to us that Splunk Enterprise Security provides end-to-end visibility. The place that you cannot see is from where you are going to get attacked.

We have a hybrid cloud environment with AWS and Azure. I am pretty confident in its ability to help us find any security event across our environment. We have put in time to feed Splunk Enterprise Security the data that we want to look at.

I am pretty happy with its ability to ingest data. When it comes to normalizing, my company could improve on that a little because we need to do more tuning of some of the data that we are ingesting. That is not much of an issue with Splunk Enterprise Security. That is more of an issue with how we are using it. We need to possibly do a little bit better in terms of how we utilize this tool.

I am pretty confident in its ability to identify and solve problems in real-time. If it has the data and you implement it properly, it will tell you what is wrong.

With risk-based alerting, we are now getting the right context for investigations. It definitely helps and speeds up the investigation. With risk-based alerting, I can see the chain of events. I can see what caused this to occur. I do not have a percentage, but I know my analysts are not getting the alerts that they have not completed by the end of the shift. Previously, that was not the case, so I am pretty pleased.

Splunk Enterprise Security has helped improve our organization’s business resilience.

Splunk Enterprise Security helps to identify and solve problems in real-time, but I do not know if it can also predict the problems in real-time.

What is most valuable?

I am enjoying our implementation of risk-based alerting. That has helped very much with cutting out a lot of the noise that we have. It has reduced our alert volume significantly. There is about an 80% reduction.

What needs improvement?

I do not like the pricing model. It is expensive.

For how long have I used the solution?

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

What do I think about the stability of the solution?

I have not had issues with its stability.

What do I think about the scalability of the solution?

It is pretty scalable. It also depends on what you are ingesting, but it does a good job with our data.

How are customer service and support?

I do not use the support that often. Normally, when I am looking for help, I just search on the web. If I am trying to build something and I do not remember the command, it is pretty easy to find.

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

I have used logging solutions. I find Splunk easier to use than other solutions such as LogStack.

With any such tool, the alert quality that you will get is based on the data that you are feeding it. If you are parsing logs and doing a good job with that, the outcome is good.

How was the initial setup?

I did not deploy this instance, but I deployed it in my last company. It was not as bad as I thought. It was comparable to some of the other product rollouts in the environment.

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

It is expensive, but it is a good tool.

It is worth the cost. I have worked with organizations that did not want to invest in a security tool. I am glad that we are taking security a little more seriously in this organization.

What other advice do I have?

I would rate Splunk Enterprise Security a ten out of ten. I enjoy it. I like it.

Makes it easier to read the index data
Pros and Cons
  • "Its alerting is most valuable. We have alerts set up in our environment for certain attacks, such as an SQL injection attempt. We have a front-facing server for the website. It is out there, and anybody can access it. When those SQL injection attempts come in, we are able to detect that with the alert."
  • "I do not have any pain points for Splunk Enterprise Security. I am still trying to learn it, but there can be more information on the education side for Splunk Enterprise Security. It would be nice if the certification path was more specific to what I use instead of being so broad."

What is our primary use case?

When we identify a threat in the environment, we try to track down whether it has moved from one system to another or there is any lateral movement. When we are trying to figure out how it got started and where it came from, we use Splunk to identify those logs. Palo Alto is our biggest index for the firewall, and we can look into those logs, see the relevant data, and correlate it into something that makes sense, so we can track down the problem.

How has it helped my organization?

For the most part, it makes it easier to read the index data. Instead of trying to look through an individual index, all the logs, and other aspects, it brings everything to one area. I can look at the relevant data that I need to identify the threat.

Splunk Enterprise Security has helped reduce our mean time to resolve. I do not have the metrics, but I know it is faster compared to the old way of doing it. Previously, we had to go through Windows logs and security logs. We had to go through each log to figure out what happened. I can pull all of the information way faster with Splunk Enterprise Security. I can look at multiple systems.

Splunk's unified platform has helped consolidate networking, security, and IT observability tools.

Splunk Enterprise Security brings all the logs into one central location to look at the relevant data and filter out the things I do not use. We are able to see the logs of multiple systems, the logs of the firewall, and the logs of the DNS and the Windows servers. It is able to bring all of that together and give a nice, solid picture of what is happening. We can read those logs faster.

Splunk Enterprise Security provides end-to-end visibility into the environment. It is very important for our organization to be able to see the threats, understand the threats, and figure out how to stop those threats. That is the importance of it. We are a casino. After what happened last year with two casinos in terms of hacking, we want to be able to stop that from happening to us. We learned a lot of lessons from what happened to the other two casino properties, and we applied them to a lot of our tools. Splunk Enterprise Security gives us a heads-up a lot faster.

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

What is most valuable?

Its alerting is most valuable. We have alerts set up in our environment for certain attacks, such as an SQL injection attempt. We have a front-facing server for the website. It is out there, and anybody can access it. When those SQL injection attempts come in, we can detect that with the alert. We get the alert in our mailbox, so we can start looking at it right away. Generally, with a SQL injection attempt, there is way more to it than just the SQL injection. There could be another 15 or 20 different types of attacks attempted during the injection. They are just trying to see if there is any vulnerability, and then they can take a shot at it.

What needs improvement?

I do not have any pain points for Splunk Enterprise Security. I am still trying to learn it, but there can be more information on the education side for Splunk Enterprise Security. It would be nice if the certification path was more specific to what I use instead of being so broad.

For how long have I used the solution?

I have been using Splunk Enterprise Security for about six months.

What do I think about the stability of the solution?

Besides the forwarder, it is nice. The forwarder ran out of space, so it occasionally has to be rebooted to clear out the space that is being utilized.

What do I think about the scalability of the solution?

We have 50 gigs of data.

How are customer service and support?

I never really had to use professional services. For the most part, everybody is knowledgeable and patient, and there is a decent amount of communication back and forth.

I would rate their support an eight out of ten. My biggest issue right now has not been solved yet. Our heavy forwarder ran out of space. It is a VM. By using vCenter, we presented more space to the drive, but we could not get the VM or the Linux OS to allocate the new space. So far, nobody has been able to help us fix that. The current solution is to just upgrade it. We are not in a position to upgrade it right now because of the workload.

How would you rate customer service and support?

Positive

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

I changed my career last year to InfoSec. I was in IT before that. With IT, if there is a problem with the system, we just look at the logs. With Splunk, it is nice to be able to have it all centralized in my location where I can look at the data relatively fast as opposed to a line-by-line.

How was the initial setup?

I was not involved in its setup. We have a bit of a hybrid setup. We have an on-prem data center and then we also have a cloud. We have Azure Cloud.

What was our ROI?

I would say that we have seen an ROI, but I do not know the numbers.

What other advice do I have?

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

Reduces alert volumes, speeds up investigations, and handles big data well
Pros and Cons
  • "If you want to understand how it can analyze or find out incidents, the visibility is good."
  • "We'd like to see a more seamless cloud-based integration."

What is our primary use case?

The solution is primarily for security incident investigation. Whenever a customer wants to monitor the environment for any security incident or events that are occurring, and they want to analyze the incident when virtual issues happen, that's when we propose Splunk. Otherwise, it's difficult to understand what kind of security event is arising in the environment.

What is most valuable?

The primary feature that is the most valuable is the correlation feature, which helps you analyze the data. If there's a lot of telemetry data at some point, Splunk can take advantage of it. It can handle a large volume of data. 

Now, with big data, AI, and all those things, the amount of security data that is generated is too high. Generally, the other SIMs face trouble when handling big data. However, Splunk itself is a very strong solution for handling lots of data. It helps the SOC team analyze data very well, and it does not crash on handling a large amount. That's a key benefit.

Our customers usually monitor multiple cloud environments. It's not very difficult. There are two ways we use Splunk. One is that they can be multiple cloud environments. The second is that it can be an on-prem and a cloud environment. We are mapping it to our one solution. 

Splunk is very flexible and it's integratable with other solutions

If you want to understand how it can analyze or find out incidents, the visibility is good. The best visibility would always be in the on-prem environment. Then, the cloud, since Splunk is not a native cloud solution like Microsoft's Sentinel, is used. We don't see a lot of challenges if we do a hybrid kind of setup, however.

I'd assess Splunk's insider threat detection capabilities to help find unknown threats or anomalous user behavior at an eight out of ten. Splunk itself uses another agent or another module to do it. Splunk does the job. It's not that it will not do the job; however, it will require more refining than other solutions in the market.

My team uses the Splunk Mission Control, topology, and attach framework features, which are really helpful. We've used it for multiple customers. We take their existing SOC or detection use cases and try to map them to the framework. From a security point of view, it obviously makes a solution more superior. With Splunk, you can catch more security incidents. From a best practice standpoint also, it is a good thing as we can configure the solution, and, according to that configuration, the entire performance is better in terms of security. 

It's very useful for assessing malicious activities or detecting breaches. It's a robust solution. 

We've been able to help customers detect threats faster. It might be 5% to 10% faster in some cases. And since we can analyze large volumes of data, we're not missing any particular data point or data set. That gives us an advantage.

Splunk helps reduce alert volume. You can reduce your alert volume based on your configuration, and it's highly customizable, so it can help you reduce alerts by a lot. It's helped us improve the quality of incidents we receive. 

It's helping customers speed up security investigations somewhat.

It improves the resilience of a company thanks to its ability to quickly analyze data.  

What needs improvement?

While it's costlier than other solutions, it's highly stable. 

The security orchestration response requires a bit of improvement. 

We'd like to see a more seamless cloud-based integration.

Their mobile features for iOS and Android could be improved in terms of quality of performance. 

For how long have I used the solution?

I've been using the solution for three and a half years. 

What do I think about the stability of the solution?

It's a highly stable product even for large customers with diverse environments. For companies that have huge amounts of data even, it does not crash. It's the preferred option when a lot of data is involved. It offers good resilience and improves performance. 

What do I think about the scalability of the solution?

I'd rate the scalability seven out of ten since it is not cloud-native.

How are customer service and support?

Technical support is good. We purchase premium support services.

How would you rate customer service and support?

Positive

How was the initial setup?

I was not involved in the initial setup of the solution. 

The solution is deployed wherever your appliance is. You deploy it where your software team wants to monitor from. Typically, that's headquarters or a company's security center. Splunk then has agents that help devices connect across geographies. For example, while Splunk may be primarily in the UK, it can cover devices via agents across Europe, and the agents can monitor other environments.

We have between two to five people who handle maintenance activities, depending on the client. 

What other advice do I have?

There is a threat intelligence management feature. However, customers don't use it in our case. Typically, customers want something superior in that nature.

Price is a major concern for most customers, big or small. However, price should not be the determining factor when seeking a solution. Users need to think about performance and quality. They need something that will help them prevent security incidents, and they need a product that will be stable. If you can monitor your environment better, you can prevent incidents that may lead to financial loss - and when incidents happen, companies can spend far more dealing with an extended phishing attack than they would on a service like Splunk that will protect them effectively. When it comes to security, while it's not necessary to have the most expensive solution on the market, you should at least seek out a solution that's best suited to your company and its needs.

I'd rate the solution eight out of ten. It's a great option for enterprise-level companies. However, a smaller customer with a smaller budget may not be a good match. They may not need such a powerful solution in any case. That said, if a customer is about to grow a lot, I might suggest Splunk as a primary option. I'd advise potential users to look at the environment size and complexity, consider the budget, and then decide if Splunk makes sense. 

Which deployment model are you using for this solution?

Hybrid Cloud

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