Splunk Enterprise Security Reviews

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

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. 

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. 

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. 

I have used Splunk Enterprise Security for four years. 

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

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

I rate Splunk support eight out of 10. 

Positive

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. 

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. 

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. 

We implement Splunk Enterprise Security for our clients. It's a security tool that centralizes data in one location, so we can gain some insights from it. We can also use it to create alerts. For example, let's say we want to find an incident in real-time, but we can't sit in a single place and stare at the screen. We can create alerts that send us an email notification or automate a response. 

Splunk helped us reduce our alert volume because we could optimize our risk-based user analytics. I estimate that we decreased alerts by around 20 percent. Splunk Enterprise Security speeds up security investigations.  

Splunk's strongest suit is its user interface. We can integrate multiple solutions and adjust settings in the Splunk interface. It's easy to manage multi-cloud environments because we can use rules to segregate the data and restrict our clients from seeing each other's data. Splunk has a lot of plugins and add-ons that provide a lot of information about our cloud and on-prem environments.

Splunk's MITRE ATT&CK framework is excellent, but I haven't used it for investigation. I'm primarily involved in implementation and development. Splunk Enterprise Security is solid detection-wise and faster than many other SIEM solutions. 

We already have an antivirus solution in our environment, so Splunk detects viruses based on that. Once the antivirus detects something, it generates an incident in Splunk that we can investigate. The detection time depends on a few factors, but we can detect a threat in two to five minutes under ideal conditions. 

Splunk could improve its default machine-learning models. Also, Splunk Enterprise's native threat intelligence isn't that good. I prefer a custom threat intelligence model. 

We have used Splunk Enterprise Security for more than three years.

Splunk Enterprise Security has gone through multiple versions, so the product is mature and stable. It's currently on version 9. 

We can scale Splunk Enterprise Security horizontally or vertically. It isn't a problem. 

I rate Splunk support 10 out of 10. Splunk has better support than other vendors I've worked with. It's better than IBM support. 

Positive

We previously partnered with IBM and used QRadar as our SIEM. Splunk is faster, and I like the look and feel better. If you are looking for the cheapest solution, some free open-source SIEM solutions exist. They can do many of the same things that Splunk can do but maybe not at the same scale. 

One person can deploy Splunk Enterprise Security in 15 to 20 days, depending on the architecture. It takes less time to deploy on the cloud. The solution requires some maintenance. We need someone there to monitor it in case there are issues. Three people are responsible for maintaining Splunk. 

Splunk costs a little more than other SIEM solutions. It would be nice if they could bring the price down a little. 

I rate Splunk Enterprise Security nine out of 10.

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. 

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. 

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. 

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

I have used Splunk for two years.

Splunk is a highly stable product. 

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

Positive

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. 

I rate Splunk Enterprise Security nine out of 10. 

Our primary use cases are for detection and remediation.

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. 

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.

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.

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

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. 

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. 

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.

Positive

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.

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.

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

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.

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.

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

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.

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. 

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. 

I have been using Splunk Enterprise Security for five years. 

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

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

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.

Neutral

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.

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

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

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.

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.

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.

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.

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.

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.

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

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.

We have 50 gigs of data.

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.

Positive

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.

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.

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

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

We are using it for our SOC. We integrated it with our SOC.

We have had a couple of benefits. We are using it as a SIEM. We do log extraction and analyze them. We also use reporting and dashboards. We are using it for security assessment. It is very helpful for us to be able to see what it has been like. Based on the incidents, we can take measures to cover any gaps.

Our security posture has definitely improved since we started using Splunk Enterprise Security. We are scaling it in stages. We are not yet using it at an optimum level. We are using 50% to 60% of it. Based on the analysis that we are doing, our security posture has definitely improved.

The end-to-end visibility that it provides is very important for any organization. It is the right tool to get end-to-end visibility. We get 360-degree visibility.

Like most organizations, we are moving to the cloud. We have a hybrid environment. We have a SaaS, PaaS, and on-prem environment. It is a very good tool for identifying security incidents. There are statistics, and we can go back and forth to see exactly what happened.

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

It is a real-time tool. What I like about it is how they are able to bring all the logs into a single dashboard. We can quickly get what we are looking for. We have queries. That is amazing.

Splunk Enterprise Security provides us with the relevant context to help guide our investigations. We are not using it completely, but based on our usage, it is up to our expectations.

Splunk Enterprise Security has helped reduce our mean time to resolve. Previously, if an incident used to take us an hour, it now takes us a few minutes.

The dashboard is amazing. Out-of-the-box dashboard is very good. It is very user-friendly. It is out of the box. With a few clicks, the dashboard is there.

Its performance can be better. Sometimes, it takes longer when we do queries.

Their support can also be better.

We have been using Splunk Enterprise Security for the last seven or eight years.

It is very stable. I would rate it a ten out of ten for stability.

Scalability is there. I would rate it a ten out of ten for scalability.

As we are increasing our cloud and on-prem infrastructure, logs are increasing. We have to come up with policies on our side for log retention and other things, but we are able to collect logs from multiple sources.

I would rate their support a seven out of ten. Its implementation was a big challenge, and sometimes, the ticket went from one person to another person.

Neutral

We were using Alert Logic. It is good, but there are performance issues with the dashboard and other things. At times, it takes ages, whereas Splunk Enterprise Security is real-time.

Its deployment is not easy. It is difficult. It is a one-time job, and once it is done, you get the benefits. 

We had to engage a third party or a channel partner. It was the right choice.

Application-wise, we have seen a lot of improvement in our application delivery. On the security side, we are still learning.

It is pretty straightforward and based on the sizing. If I compare it with other competitors, it makes sense.

We looked at LogRhythm, but Splunk is more mature.

I would rate Splunk Enterprise Security a nine out of ten. It is not a ten because of the support.

We use the solution for detection, basic building searches, and creating many dashboards for investigation purposes. We have also been using it recently to create some RBA detection rules.

The solution's newly developed dashboard is pretty amazing. The full platform is quite useful, and there are a lot of tools that we can use to leverage and modify for our own purposes. Clients don't necessarily know about it, but the tool is powerful because it saves so much time.

The solution has so many features that it's easy to get lost. Many of my clients want to get better at Splunk, but they're afraid of using the tool because they feel it's too complex for them. They also need to go through a certification to use the tool.

I have been using Splunk Enterprise Security for five to six years.

The solution's stability is a lot better on the cloud than on-premises.

The solution’s technical support is good. Sometimes, the technical support team's response time depends on the severity of the alerts. Sometimes, we don't get the right person on the call.

Positive

I use solutions like ArcSight, Exabeam, and Sentinel for different clients.

The solution’s initial setup is easy and not that difficult.

Our clients have seen a return on investment with the solution.

Splunk Enterprise Security is an expensive solution.

It is extremely important to our organization that the solution provides end-to-end visibility into our environment. Usually, a lot of companies don't have full visibility on their endpoints or servers.

Splunk Enterprise Security is a really good tool for helping us find any security event across multi-cloud, on-premises, or hybrid environments, like finding a needle in the haystack.

The solution has improved our organization’s ability to ingest and normalize data. Splunk Enterprise Security has also helped us identify and solve problems in real-time.

When processed correctly, the solution provides us with the relevant context to help guide our investigations.

If everything works correctly, Splunk Enterprise Security helps speed up our security investigations by 50%.

The solution has helped reduce our mean time to resolve by 20%.

When something breaks with the solution, troubleshooting and figuring out the problem is hard. The solution runs better on the cloud, with fewer problems and errors, than on-premises. We may not have the right hardware on-premises.

Splunk Enterprise Security is a great app that has been really innovative in the past. I would recommend the solution to other users. There's a cost to it, like anything that is of quality. However, if you want the best, Splunk is at the top right now. The solution is deployed on AWS and Microsoft Azure clouds.

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