Splunk Enterprise Security Reviews

We primarily use the solution for SOC purposes.

The solution has made it possible to check and detect our traffic a bit better.

The incident review is great for working inside of a SOC if we want to see everything and we want to configure notables and have all notable features, it's useful. We're moving to SOAR right now for configuration for our work center. As far as ES in our work center, just detecting our notables and monitoring all our traffic, is the most important feature as far as what our day-to-day is concerned. 

Splunk has helped us with mean time to respond, although I don't have exact numbers.

Splunk has helped improve our company's resilience level.

Splunk is very good at predicting, identifying, and solving problems in real time. I've never used anything else, however, I'm impressed with the ease of it and the ability to find anything and everything we need. 

I do a lot of the maintenance. A lot of my workers are fresh into Linux and need to monitor, manage, and do maintenance on it. They should bring back the maintenance mode button. Splunk used to have it and they took that feature away.

The upgrading process could be smoother. 

I've used the solution for about a year.

The stability and availability of Splunk are great. It does get weird when we initially update items, however. That's the only time we see issues. It may try to input data in areas it doesn't need to. That said, we are aware of the quirks of the setup. 

Scaling is easy if you have done it a couple of times. 

The environment I have has multiple servers. We might have around 100 servers. 

Splunk support is very communicative about our concerns. That said, the answers I've gotten back don't make sense. I'm not sure if they communicated our issue in the right way or if they misunderstood, however, they did not correctly address our issue. In the end, we do have a good dialogue. I now expect that they will misunderstand the problem on the first round and we have to go back and forth. The effort is there to try to understand. 

Neutral

The company may have had QRadar for a while before Splunk. I wasn't around when they switched to Splunk so I cannot compare the two. 

I was not involved in the initial deployment of Splunk. 

The company has witnessed an ROI in terms of the amount of time saved via being able to tweak our searches. The docs are great. They help tremendously in filling knowledge gaps. The ROI is solid. 

I don't deal with pricing or licensing. 

I've only worked with Splunk as far as data ingestion. 

The solution does take a bit of understanding. It does need improvements in some areas. I'd rate the solution seven out of ten. 

My use cases are very limited. I use the product mostly to detect internal threats like data exfiltration.

I am a basic user. The search lookups are useful.

The product must improve insider threat detection. Almost everything is outside in, but not inside out.

I have been using the solution for four years.

The solution is very reliable. I like its stability. It always works.

Sometimes, it takes time when we need additional information or something extra. However, the tool’s able to do it.

I haven’t contacted the support team. I reach out to the internal expert. My searches and my requirements are very basic. The expert is great. He’s always able to help me and guide me.

Positive

We do see a return on investment. The product saves us time by automating reports and helping us see data.

The solution helps reduce our mean time to resolve. It’s great to automate some tasks. I believe Splunk has helped improve our organization’s business resilience. We have become stronger in insider threats by just stopping things, being able to show what is leaving, and taking action on it. It's very useful when I try to identify events.

When I started working in my organization, they were using Splunk. Overall, I rate the product a nine out of ten.

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.

There are lots of use cases such as finding threats, attack factors, and logs. It helps with rogue DNS or brute force attack detection. We have logs related to why a particular account was created. There is alerting. We can get some false positives, but by fine-tuning some of the things, we can reduce false positives.

Splunk is a security monitoring tool. It helps with incident handling, data logging, and observability of metrics. Splunk can handle all these things. Splunk Enterprise security is a premium app of Splunk through which we can have all the threat intelligence and incident reviews. It helps in finding all the attacks and Advanced Persistent Threats (APTs).

We also have dashboards. We can collect logs from different sources and applications. We can also troubleshoot issues. If we are having any issues with an application, we can go to that particular index to see what is the cause. If any application is failing or giving an error, we can troubleshoot the issue. We do not have to log into the server to find the error.

We monitor multiple cloud environments. We have GCP, Azure, and AWS. It is easy to monitor multiple cloud environments using the Splunk Enterprise Security dashboards. Splunk releases inbuilt apps, so by using those apps and add-ons, we can integrate it with our cloud environments. For example, for Azure, they have a Microsoft Cloud Services add-on. We need to register the app in Azure, and after registering the app, we have to use the tenant ID and set it up. There are a lot of inputs, and we can use all those inputs to onboard different logs from Azure. There is also the capability for HTTP event collection.

We have a hybrid environment, and that works best for us. For a lot of things, we cannot just go fully cloud. Hybrid is the best option for us. We are happy with the visibility that Splunk Enterprise Security provides. It is also about how we configure things. If we do not do it in the right way, we will not get visibility. We have to know what kind of tools we are using and what kind of data we are pulling. We cannot pull everything. We have to know what to pull. If we pull only what is required, we would not have any problems.

Splunk Enterprise Security comes with MITRE ATT&CK and Cyber Kill Chain frameworks by default. There are 12 processes in the MITRE ATT&CK framework. We just have to onboard logs, create the data models, and assign those ATPs to monitor all the kill chains. We can monitor all attack vectors and persistent threats that we want to monitor.

Splunk Enterprise Security is good for analyzing malicious activities and detecting breaches. I would rate it a 9 out of 10 for that. It can also go to 10 for different clients based on different requirements.

Along with Splunk Enterprise Security, we also install another Splunk app that has all the threat intelligence. We then feed the data through a CSV file and create the use cases. We set up alerts for those. In the case of an event, an alert is generated and assigned to a particular SOC analyst. There can be some false positives, but with proper configuration and filtering, they can be reduced.

Splunk Enterprise Security has been very beneficial and valuable for us. Our application teams can use the indexes to troubleshoot the issues they are facing at their location.

Being able to ingest data from all the tools and all the apps being used in the environment is valuable. Being able to create alerts when, for example, the CPU usage reaches 95% is also valuable. We can set up alerts and proactively fix the issues. Splunk helps with all these things, and Splunk Enterprise Security has almost 2,000 use cases. It follows MITRE ATT&CK and Cyber Kill Chain frameworks. There are certain notable events for which we can configure our security posture. We can onboard all the logs through indexes and create dashboards to view what is going on in the environment.

Overall, it is pretty good. They are improving it every day. They recently released SC4S for onboarding syslog data. However, the support and the pricing can be better.

It has been 8 years since I have been using Splunk. I am not a part of the core security team. I handle some parts of enterprise security, such as SIEM data models or the creation of some correlation searches and use cases. The majority of things, such as threat hunting or threat intelligence, are managed by our core security team.

We faced some issues, but we fixed them ourselves. We have around 10,000 knowledge objects running. All the knowledge objects should not be running all the time. They should be distributed over 24 hours so that the servers do not have any extra pressure at a particular time. We used to have an issue with our indexes going down. The CPU was being utilized 100%, and everything was getting stopped. We found the issue. We fixed that, and we are good now.

It is pretty easy to scale. For Splunk Cloud, we log a ticket with Splunk support, and they start the process. It does not take much time. However, there is a cost involved in that. 

We have been ingesting 40 TB a day. We have three locations: The USA, the UK, and France.

The SLA for Splunk Cloud support is not satisfactory for a customer. The turnaround time is a bit low. That should be fixed. I would rate their support a 9 out of 10.

Positive

I have not used any similar solution in my current organization.

In my previous organizations, I have used solutions such as Elk, IBM QRadar, and Microsoft Sentinel. Microsoft Sentinel is good. Splunk is better than QRadar. Splunk has a lot of capabilities. It makes it easier to do many things and do them correctly. It does not require as much effort as required in IBM QRadar and Microsoft Sentinel.

Splunk is a bit costly, but if we control our usage during our searches, its cost is okay. When not controlled, it becomes a bit costly.

To those evaluating Splunk and solutions, I would advise knowing the features they would be getting. Elk is open source, but there is an underlying cost of infrastructure. The cost almost becomes the same. You have to hire people who can work on Elk and then you have the underlying infrastructure cost.

We were on-premises, but we recently moved to Splunk Cloud. We have been using Victoria for the last eight months. When going from on-premises to Splunk Cloud, Splunk recommends engaging professional services. 

The migration was done by Splunk. For administration and maintenance, we have about eight people, but the number of users in the environment would be in the thousands.

The maintenance of Splunk Cloud is taken care of by Splunk. Customers do not manage the clusters. With the on-prem setup, we have to patch the servers, upgrade the servers, or restart them from time to time so that the rebalancing of the buckets happens properly. In Splunk Cloud, we do not have to do these things. We only take care of the data normalization part. All other things are managed by Splunk.

It does provide a return on investment.

It is a bit costly.

Be clear about what you want and try to filter out as much as possible. Create role-based rules and assign them to users rather than assigning every role capability to all the users. Also, everyone should not have access to all indexes. Only certain people should have access. For example, if someone is from the AD team, he or she should have access to the particular index logging the AD logs. They should not have access to all of it. There should also be some kind of training before you give access to people so that they know which searches to use and which ones not to use. They should understand the impact of various things.

I would rate Splunk Enterprise Security a 9 out of 10 based on my experience and the work that I do with the core security team. They are pretty satisfied with it.

We use Splunk Enterprise Security for continuous monitoring, ensuring compliance, and advanced threat protection.

Splunk Enterprise Security allows our customers to view their decentralized infrastructure from a single pane of glass.

Splunk Enterprise Security's insider threat detection capabilities are good.

The actionable intelligence provided by the threat intelligence management feature is effective. The solutions are integrated into the platform, and customers receive operational insights.

The MITRE ATT&CK framework's ability to help our customers discover the overall scope of an incident is high.

Splunk Enterprise Security is good for analyzing malicious activities and detecting breaches.

Splunk Enterprise Security helps our customers detect threats faster.

Splunk Enterprise Security is able to process a huge amount of data without any issues. Our customers can see the benefits two to three months after deployment.

Splunk Enterprise Security helped our customers reduce their alert volume by 40 to 50 percent.

Splunk Enterprise Security helped speed up our customer's investigation time by 60 to 70 percent.

Splunk Enterprise Security can be improved by including backup network detection and response and safe management to the paid platform.

Splunk Enterprise Security's price is high and could be lowered.

I have been using Splunk Enterprise Security for two years.

I would rate the stability a ten out of ten.

I would rate the scalability a ten out of ten.

The technical support response time is delayed and they can take two to three days to respond sometimes.

Neutral

The initial setup can be complex for customers who require advanced configurations and customizations, but it is straightforward for basic usage.

The deployment process is simple. We first identify the platform and determine if it is a unique system. Then, we define the virtual environment. After installing Splunk's platform, we perform the necessary configurations and other tasks. Splunk Security Essentials is a premium add-on for this tool, which is installed on the Splunk Enterprise platform.

The number of people required for the deployment depends on the customer's requirements and the use case they are developing. For example, if the customer needs to gather data from their network, we will need to add network experts to the project. However, if we already have experts who are familiar with the API and application connectivity, we may not need to add any additional people. Ultimately, the number of technical resources required will depend on the specific needs of the project. On average, we require four to five technical people for deployment.

Splunk Enterprise Security's price is high. I would rate the cost as ten out of ten, with ten being the most expensive.

I would rate Splunk Enterprise Security an eight out of ten.

There are many cheaper solutions available on the market but Splunk Enterprise Security is worth the cost.

Two people are required for maintenance.

The value Resilience offers our customers is good.

The primary use case is security and data analytics. In general, we manage and maintain it for our customers.

Application-wise, it's good. Searching and reporting of data analytics is also fine. The dashboard presentations are also a good feature. Overall, its functionality is great and that's why we use it.

I would like additional support for custom add-ons, as well as cloud integration. Right now we have concerns because we have to customize applications for direct integration. But on-prem, it is all functional. We have to build it on our own. Previously, they developed custom connectors or add-ons for a lot of applications. But that number can be upgraded still. There are a lot of applications in the world that are not supported.

I have been using Splunk Enterprise Security for over two years. I received Splunk certification six years ago.

The stability of the functionality is good, but there are still bugs that keep hindering things. I am waiting but they are there and that is quite common. I think they have not yet been resolved from the older versions. The stability is a seven-plus out of 10.

It's scalable for all environments. Splunk Cloud can be scaled to a small or medium company, depending on their inputs or log resources. Businesses at the high end of medium-sized, and large companies, can go with the on-prem solution.

The technical support is good. 

However, there is a lot of delay nowadays. The last time we raised a case, it took quite a long for them to come back with their first response. That's not for a P1 or P2, but if it is a P3, they don't respond at the earliest. When they respond, it is quite late and we have to ask again. The first response is never an answer. It's always a query.

Still, the people I have worked with there are all an eight-plus out of 10.

Positive

It can be deployed on-prem or in the cloud. With the latter, it is Splunk's own cloud. 

The deployment of the solution is straightforward, but there is a lot of engineering activity involved in designing the architecture. Architecture-wise, it is fine, and bringing things together is not that tough, but maintaining and managing it is a tough job because we don't work in a normal environment. We work on something that is very defined to the network. That means we have to build everything from scratch and deploy it.

The implementation strategy depends on how the customer wants things done. But in general, I go through research and then develop and design. I ask the client what sort of environment is flexible or cost-effective for them. It's done in stages. It's a matter of understanding the infrastructure and then implementing,  or designing and handing it over to them.

If there are 1,000 log sources, it takes six months to a year to deploy, depending on how the customer is supporting the process.

Every on-prem solution involves maintenance, including keeping things upgraded, whereas Splunk Cloud is managed by the vendor. The number of people involved in on-prem maintenance depends on the size of the environment and how long our update window is. For example, if we have a green zone at midnight for three hours, and we want to upgrade at least 20 to 30 servers, it will take eight to 10 people working in parallel. But for a very small environment of 10 servers, it will take four people to manage it, or if we have a large window, even three people can do it.

We do it ourselves.

The pricing depends on the bandwidth of an organization and is good compared to some SIEM tools. IBM, for example, is quite costly. But Microsoft Sentinel is notably cheaper. I have seen a lot of organizations running on Sentinel.

IBM is for quite large organizations that don't want to have their data on the cloud. Splunk has both on-prem and cloud modules and, cost-wise, Splunk is better. Internally, we cannot push everything to the cloud. That would become too expensive for us. So we have it sitting in our data center and that is good.

I have worked with a number of other solutions including RSA enVision, IBM QRadar, as well as Microsoft, McAfee, and LogRhythm. 

If we want to build an add-on feature in Splunk, we have to build an application and then integrate it. But in other applications, there is a direct integration that only requires partial development and it will start functioning.

Also, there is something called correlation in a lot of other tools. Splunk also has it but it consumes a lot of memory. If we tag all the data, it is better, but tagging consumes storage and it makes it a little tough for us to run a search. 

If we want to work towards SOAR, if there were a little bit more integration so that our customers could taste SOAR, they could then move to Splunk Phantom or other tools. Right now, people are not using automation. Everything is done manually. Hopefully, that's the next goal. Security operations will surely use SOAR and, once they start tasting it, they'll get to know how it works. They can design playbooks and start using it. That's an additional feature I would like Splunk to bring in. 

Splunk's advantage is its search capability. Its search is notably faster. With Splunk, I can search easily on keywords. That is great. It also has something called "stats" and it runs much faster. Within minutes, it gives the data from a very large set. Spunk's dashboards are also a very good thing. No other application or tool is as versatile in presenting the dashboard. It all comes down to presentation. It may take a little bit of engineering work to develop and customize, to parse the fields and fetch the data, but the presentation is good.

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 to monitor our network environment for abnormal activities and threats.

We easily monitor multiple cloud environments with Splunk Enterprise Security.

Insider threat detection helps our security posture.

I use the threat intelligence management feature whenever I do a threat analysis.

When Splunk detects breaches and malicious activities it notifies our IT team so they can analyze the notifications and respond accordingly.

Splunk has helped our organization by allowing us to gain valuable insight through the analysis of large datasets.

The customizable dashboards are user-friendly and visually appealing.

It has helped reduce our alert volume.

It has helped speed up our security investigations.

The most valuable feature of Splunk Enterprise Security is website activity monitoring.

While Splunk Enterprise Security offers valuable features, its cost is high and could be more competitive.

I have been using Splunk Enterprise Security for around five months.

Splunk Enterprise Security is stable.

We frequently connect with the support team to review our options. They resolve our issues quickly.

Neutral

We also use IBM QRadar but Splunk Enterprise Security is more functional and user-friendly.

Splunk Enterprise Security is expensive.

I would rate Splunk Enterprise Security eight out of ten.

For someone who wants to use the cheapest solution, I would tell them that this is the best solution and worth the cost.

I recommend Splunk Enterprise Security to others.
