Splunk Enterprise Security Reviews

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 Splunk Enterprise Security for security log investigation. It is a SIEM platform. Many cybersecurity and technical alerts generated by Splunk turn out to be false positives. We then analyze these alerts to determine if they indicate a genuine security threat.

We will be ingesting logs from various sources, including firewalls, databases, Windows devices, and Linux devices. These logs will be used to investigate security incidents and troubleshoot system issues. Our use cases will be brief and focused, allowing us to leverage pre-defined queries in Splunk for efficient analysis. These queries will trigger alerts based on specific security or operational criteria within the predefined use cases. We will then investigate the triggered alerts by further analyzing the corresponding logs.

Splunk Enterprise has improved our incident response time. For instance, if an end user attempts to log in to a system with an invalid password from a device using an unusual port number, we will receive an immediate alert. This could be indicative of a brute-force attack aimed at stealing credentials, making it a suspicious activity. This is just one example of how Splunk Enterprise enhances our security posture.

Splunk's threat detection capabilities are strong, and Splunk is a leading platform for SoC monitoring. To maximize effectiveness, we need to develop strong query-building skills. Additionally, we have the flexibility to fine-tune existing queries or remove them altogether once an issue is resolved.

The customizable dashboards of Splunk are good for visualization. It gives a better understanding, and the graph is highly customizable.

I would rate Splunk Enterprise Security a nine out of ten for analyzing malicious activities.

Splunk Enterprise Security helped the organization control suspicious and malicious activities.

Splunk Enterprise Security has helped speed up our security investigations.

Splunk Enterprise Security's customization capabilities enable integration with other tools like EDRs, providing real-time event insights.

I like the Splunk dashboard and search engine.

Although the technical support is adequate, there is still room for improvement.

I have been using Splunk Enterprise Security for 2 years.

I would rate the stability of Splunk Enterprise Security 9 out of 10.

I would rate the scalability of Splunk Enterprise Security 9 out of 10.

The technical support is adequate.

Positive

I would rate Splunk Enterprise Security nine out of ten.

While I understand the desire for a cost-effective SIEM solution, prioritizing security over budget is crucial. In cybersecurity, even a seemingly minor breach can have significant consequences. Therefore, choosing the best SIEM for your needs, even if it has a higher upfront cost, can ultimately save money and protect your organization.

We have Splunk Enterprise Security deployed in four locations in one country.

Splunk takes care of the maintenance of the solution.

I recommend Splunk Enterprise Security to others.

We use it in our company to log everything. We use tools like XSOAR to take appropriate actions to mitigate threats.

Splunk Enterprise Security has aided our organization in the way it provides great visibility and helps with what our company's users do with it.

I like how easy it is to integrate the logging of all of the various nodes. The product also offers nice connectors. Other features include the product's ability to allow users to customize their dashboards, signatures, metrics, and other elements, making it a very valuable and reliable tool for my organization.

I don't know if there is a need for any improvements in the product since it is one of my peers and not me who is directly responsible for Splunk Enterprise Security in our company, so I will have to ask him if there are any requirements associated with the product.

The price may be an area of concern where improvements are required. Splunk Enterprise Security doesn't indulge in whitewashing, but Cisco does it too much.

I have been using Splunk Enterprise Security for two years.

I have not seen any outages in the product in the past two years that it has been running in our company, so I think it is good when it comes to the stability part. I have had an experience with the vendor during which there were two products, one from the vendor and the other from Splunk Enterprise Security, and we saw that one of them was not able to capture all the logs appropriately, after which our company had to figure out whether it was Splunk API or the vendor's tool.

I have never used the product's customer support. My peer has contacted the product's technical support team, and it has worked very well for him.

My company used to use one of the spin-offs from IBM. My organization has used IBM QRadar.

Though I am not sure about the deployment model, I feel that since it may not be on Azure, the product must be deployed with the help of AWS.

I have experienced an ROI revolving around the product's dashboards, metrics, and other such related stuff, but I don't know how to quantify them. My peer would be the best person to speak about the product's ROI.

My peer would be aware of the product's pricing part.

There was a pre-vendor selection approach my company followed, but I don't remember the names of the products involved.

It is pretty important how the solution provides end-to-end visibility in our company's environment because it provides opportunities for shadow IT and for people to do things that they should be doing. If one is appropriately logging in, the product gives us a view and helps our company discover things that we didn't know about.

In terms of Splunk Enterprise Security's ability to help our company find any security events across multi-cloud, on-prem, or hybrid environments, I will have to say that since we are still using it, it has to be effective. If it wasn't effective in the aforementioned area, my peer would have found something else in the product. I don't have enough personal insight into Splunk Enterprise Security's ability to help our company find any security events across multi-cloud, on-prem, or hybrid environments.

Splunk Enterprise Security has helped to reduce my company's alert volume. Our organization does get alerts, and we are trained for them. I will have to ask my peer to give me the exact number associated with the alerts my company receives.

The solution provides the relevant context that helps guide our company's investigations. The context information has impacted our company's investigation process as it definitely speeds it up because we have only a single source from which we can get that, and it helps us understand what may have taken place in a particular incident that we are looking at in our organization. In our company, if we look at any of the other services, we can see whether a particular or specific user touched just a single system or ten different systems.

The solution has helped reduce my company's mean time to resolve, but I don't have numbers to explain it.

The reason why I rate the tool a nine is because of the flexibility it provides to go back to the dashboards. The flexibility to be able to customize standard dashboards and other standard things that I want to be able to grab and have them pop out and then be able to create some sort of an action against those kinds of things that I want, of which the first is the standard reporting part, which is very valuable.

To those planning to use the solution, I would suggest that they need to get Splunk to work hard on the pricing part. People also need to encourage Splunk to stay true to its roots because I have seen what has happened to some of the other tools in the market. Splunk has been acquired by Cisco. You want Splunk because of its capabilities, not because of what Cisco wants to give you.

If I consider my company's needs, I rate the overall product a nine out of ten.

We are using the solution for security. We can use it to track what has happened in our network. We can check via dashboards and alerts. We can use it for load balancing and high-performance tasks. We use it to analyze data and logs. It normalizes logs and we can detect attacks, such as brute-force attacks. We can receive information from our firewall, our Fortigate. Since we receive a lot of traffic, we have to investigate events using the solution. It provides updates on attacks. The solution helps us report on what happens in our network.

We use Splunk for security and tracking what happens on our network and it is effective at that.

We like the big data analyzer.

The dashboard and alerts are good. We can use them for monitoring to see what’s happening on our network. It’s centralized. It gives us good visibility into multiple environments. We can use it in Windows, Linux, et cetera.

We can use platforms and integrate everything together. We can see multiple environments on-premises.

When something happens, we get alerts via SMS or email. 

We use the MTTR attack feature and it is very effective to use for detecting threats.

We can also schedule reports on a monthly or weekly basis.

It’s very useful for tracking. If you can look at the steps and see what happens, you can investigate effectively, and so on.

Splunk Enterprise Security is excellent for analyzing malicious activities and detecting breaches. We can see, step by step, what happened. We can escalate and investigate and so on.

Splunk has helped us detect threats faster. The alerts are very effective.

It helped to reduce alert volume. I’m not sure precisely how much, however, it depends on how many client devices you are tracking and analyzing.

Splunk is a suitable resource for collecting logs. 

The threat intelligence management feature is something we cannot use.

We'd like Splunk to reduce false positives. 

It would be helpful to be able to configure everything a bit more. If your network is very big, it's important to customize.

The dashboard could be improved so that tracking and analysis could be better visualized.

I've been using the solution for two years. 

The solution is stable. If you have suitable resources and buy and use the correct license, you'll get fine performance. 

The ability to scale Splunk depends on your network. If it is big, you can add more resources easily. You can use a cluster and several servers. 

When you work on Splunk, it's very easy. However, when you need to reach out to support, it could be better. It would be helpful if they could respond faster. 

Neutral

I have experience with another solution called ELK; I find Splunk better, even though it is not free to use.

I've done one implementation. I installed it across several servers. How long it takes depends on the project. It also depends on how many resources you have. If it's just a small setup it might take two hours. 

The product is easy to maintain. 

I'm a customer. We cannot use the cloud versions as we are based in Iran.

I don’t have experience with the Spunk Mission Control feature.

I've worked with Splunk so far and while it's very easy to use it's not free. There are other solutions that are open-source that you could use, however, I find Splunk to be worth the price and I'd recommend it to others. 

I'd rate the solution ten out of ten. I would recommend Splunk to others.

Our customers utilize Splunk Enterprise Security for either their cybersecurity program or their data warehouse program.

Splunk Enterprise Security's threat detection capabilities are effective in assisting organizations to uncover unknown threats and identify anonymous user behavior. However, this effectiveness is dependent on using the UBA modules and having the proper infrastructure in place.

MITRE ATT&CK is the framework that we use to detect and track well-known threats. When there are well-known threats, we can utilize the MITRE ATT&CK to identify any anomalies.

Splunk Enterprise Security has its own routine and process defined for analyzing malicious activities and detecting breaches. Mainly, we baseline the client's business process and day-to-day activity and then use it to detect malicious activity through various scenarios.

Splunk Enterprise Security assists us in detecting threats more quickly. We have an abundance of unrelated and meaningless data from the raw logs, and the solution aids us in organizing and correlating this data so that we can extract meaningful events and take appropriate action. This is the primary objective for the majority of our clients. 

In most cases, we provide monitoring and intelligence to our customers based on how they use the solution. This allows other technical teams, such as PC, system support, and other tech units, to take appropriate actions. Our main role is to provide them with alerts and use case scenarios, while the detection and actions are primarily related to other aspects.

When we initially implement Splunk Enterprise Security, there are many alerts and false positives. However, with time, we are able to align our configuration with the client's requirements and do more baselining, reducing such issues.

Splunk Enterprise Security helps to expedite security investigations. Without a security solution, our security team is unable to identify threats because the log and auditing data are unrelated and uncategorized. Consequently, we cannot access them promptly. Therefore, having a solution like Splunk Enterprise Security is crucial for our cybersecurity program. For certain clients' needs, we prefer using open-source applications like ELK and ESK. However, if they opt for an enterprise and commercial product, Splunk is among the top three choices.

The most valuable feature is the DSS, also known as SPL, because it allows users to script advanced queries with limited knowledge.

The CIM model is the method Splunk uses to normalize data and categorize its important parts, but it is quite complex. Simplifying this process would assist security officers in assessing threats and using the system more efficiently.

I would appreciate it if Splunk could add the feature of importing and exporting from web servers and third-party devices during project and process development. This addition would greatly enhance the value of the solution making the maintenance for the security officer easier. 

I have been using Splunk Enterprise Security for six years.

I rate the stability of Splunk Enterprise Security an eight out of ten.

Splunk Enterprise Security can be easily scaled once it has been installed and deployed.

Cyber threat levels are increasing every day, especially during the pandemic when most employees needed remote access to their business services. As a result, many organizations experienced a surge in attacks and required a resilient SIEM and cybersecurity solution.

I have used ELK, ESK, QRadar, Graylog, and LogRhythm in the past. One of Splunk's strengths over its competitors is its dedicated DSS called SPL.

The drawback of Splunk Enterprise Security is that upon initial installation, we need to do a lot of customization in order to have an effective cybersecurity program and deliver quality service to the client.

The initial setup is straightforward, but we need to make some configurations afterward that can be a bit complex. The deployment time depends on the size, but it usually takes several months to ensure stability and requires two SIEM engineers.

Splunk Enterprise Security is hardly affordable for most of our clients, causing many of them to resort to using open source solutions instead.

In addition to the licensing fee, there is also a support and maintenance charge.

I would rate Splunk Enterprise Security an eight out of ten due to its high total cost of ownership, difficulties in maintenance, and the complexity of configuration immediately after deployment. 

Splunk Enterprise Security may not be cost-effective for small and even some medium-sized companies. While each organization has different requirements, we do recommend Splunk for medium and large organizations.

Organizations should take into account the complexity of their environment. For instance, if they have a purely vendor-based environment for their network security appliance, it may be easier for them to handle security, fabric, and architecture requirements. However, if they operate in a multi-vendor and mixed environment, they need to conduct more research on how to integrate various components. Often, they rush into negotiating their cybersecurity program without sufficient research, leading to potential problems for clients.

We use it alongside some endpoints to detect log ins outside of scheduled work hours. If someone logs in outside of that range, we generate an alert for the security team to review.

I can use the MITRE ATT&CK framework. With the data that I ingest into ES, the MITRE app gives me visibility into what I'm covering from the techniques and tactics in the framework, which is pretty cool and convenient.

At the end of the day, it's the platform receiving the logs from all the other apps. You're watching all the information in just one place, so it's basically the core tool in the company. So, it is really important that Splunk Enterprise Security provides end-to-end visibility into our environment. 

In a way, Splunk Enterprise Security helped improve our organization's ability to ingest and normalize data. However, there are a few tools that are hard to normalize or use data models. And some of the add-ons don't work properly sometimes. Not all of them, but a few.

Splunk Enterprise Security helped us reduce our alert volume by 30%.

Moreover, Splunk Enterprise Security provides us with the relevant context to help guide our investigations. And it's important because we need to set up the basis of the context of what we want to see.

Splunk Enterprise Security helped improve my organization's business resilience. It's a pretty powerful tool. We can monitor and ingest all the data, only if it's not encrypted.

Splunk platform helps consolidate networking, security, and IT observability tools. We watch all that information on just one platform, so that's pretty cool. 

The risk-based alerting (RBA) is one of the valuable features. It's a really cool concept to explain and see the impact that you're having on the company.

Splunk Enterprise Security's ability to find security events across different environments, whether in the cloud, on-premise, or hybrid, is really good. Because it gives me a lot of content out of the box, the only thing I need to do is ingest the data, and I'm good to go.

I would like to see the asset and identity lookups be more automatic and less manual. I have to search everything and type it. So it should be more user-friendly.

I have been using it for six months. 

The stability is really good. It's very accessible.

Most of the time, some docs are not available. When you see the documents, they add a link, we go to the link but it's not available. 

Also, the customer service and support have a lot of old questions that are not updated.

Neutral

It's pretty easy. The first thing you need to do is the onboarding phase. After that, you need to review that the logs that you're receiving are good. And after that, you need to start working with the correlation searches and setting up everything.

The deployment was done internally. 

We have definitely seen an ROI. It is worth it!

The pricing is always going to be different because it depends on the project you are working on and how much data you are going to ingest. But it's definitely worth it.

We directly chose Splunk to begin with.

Overall, I would rate it a nine out of ten. There are a few things that need to be more automatic because there's still a lot of manual work to use it.
