There are quite a lot of things that we find useful. Splunk agents are useful and good. Its UI is quite impressive.
Senior Information Technology System Analyst at a computer software company with 5,001-10,000 employees
Impressive UI, many useful features, and very scalable, but needs alerting feature and better pricing and integration
Pros and Cons
- "There are quite a lot of things that we find useful. Splunk agents are useful and good. Its UI is quite impressive."
- "Its pricing model and integration with third-party services can be improved. We had faced an issue with integration. The alerting feature is currently not available with Splunk, but it is definitely available with Datadog and PagerDuty. They should include this feature. A few dashboards in Splunk look quite old and are not that modern. They aren't bad, but improving these dashboards will definitely make Splunk more attractive and usable. I read in a few blog posts that there were a few security incidents related to Splunk agents. So, it can be made more secure."

I have not interacted with them. Another team is taking care of raising tickets with their technical support.
How was the initial setup?
It is quite simple.
What's my experience with pricing, setup cost, and licensing?
Its pricing model can be improved.
What other advice do I have?
A few years ago, I would have definitely recommended Splunk, but nowadays, better alternatives are available. We are currently exploring a few other alternatives, so I won't recommend Splunk as of now.
I would rate Splunk a seven out of ten.

Seamless integration with devices and operating systems, centralized management and control, and proactive support
Pros and Cons
- "The integration is seamless with many devices and operating systems."
- "Being a SIEM solution with a centralized dashboard, we would like to have more options to customize it."
What is our primary use case?
We are a solution provider and Splunk is something that we provide as a service to our customers.
What is most valuable?
The most valuable feature is the reporting and the information that is provided by the tool.
It is very easy to implement a PoC using Splunk, which will show the value of the reporting and data that it provides.
The integration is seamless with many devices and operating systems.
It is flexible enough that you can choose what kind of deployment model you want.
They have a large solution toolkit that supports IoT, wherein businesses can get a lot of help with the centralized management functionality. There are also tools to assist from the security and SIEM perspective, and there is a centralized dashboard.
What needs improvement?
Being a SIEM solution with a centralized dashboard, we would like to have more options to customize it. It should be easy to customize dashboards.
When we are monitoring something, we would like to have a more granular outlook. Splunk has a good dashboard that is easier to use than some competing products, but better customizability would be a great help for the users.
For how long have I used the solution?
We have been working with Splunk for approximately three years.
What do I think about the stability of the solution?
This product is very stable.
What do I think about the scalability of the solution?
Splunk is a very scalable solution. Being a Japanese product, they will ensure that all of the features work in any environment. It is very heterogeneous. It can integrate with Windows, Linux, AIX, HP-UX, and Solaris. It also supports IoT devices, mobile phones, and more.
We have more than 150,000 people using our services.
How are customer service and technical support?
The Splunk team has good, proactive support. Also in terms of assisting with the installation, they are quite good.
Which solution did I use previously and why did I switch?
Splunk is similar to IBM QRadar, which we also have experience with. However, Splunk has advanced SIEM features included with it, so we often use it to satisfy this requirement. Whenever an organization is looking to implement SIEM, they have the flexibility to choose Splunk, QRadar, or the ArcSight Logger solution.
One of the major differences that I see between Splunk and QRadar is that Splunk gives the users fewer devices, so they can do things quicker.
How was the initial setup?
The installation for Splunk is easier than competing products QRadar and ArcSight.
We have Splunk deployed on the cloud so that we can provide the service, but some of our customers have it installed on-premises.
All the user has to do is download the Splunk server agent, install it on the laptop or endpoint, integrate 50 or 100 devices, then see what kind of reporting is available.
What about the implementation team?
We have an in-house team for deployment in maintenance. Splunk is a tool that does not require much staff to maintain. The users can start with a PoC, simply learn it, and deploy it for themselves. They don't require subject experts to be hired for the installation and configuration.
What's my experience with pricing, setup cost, and licensing?
Price-wise, if you compare QRadar to Splunk for SIEM functionality then they are in the same range but when you integrate SOAR with these solutions, Splunk takes the lead and is more competitive.
What other advice do I have?
This is a product that I recommend for anybody who wants and advanced SIEM solutions. Of the three that I have used including QRadar and ArcSight, Splunk is the one that I prefer.
I would rate this solution a nine out of ten.

Assistant Manager System at a financial services firm with 10,001+ employees
Stable, with easy log connection and the capability to scale
Pros and Cons
- "Its compatibility with other SIEMS is very useful."
- "We find that the maintenance process could be a lot better."
What is our primary use case?
What is most valuable?
The ease of log connection has been great.
Its compatibility with other SIEMS is very useful.
They have many basic use cases that we like.
The cloud version of the solution is especially scalable.
The product has been quite stable so far.
The initial setup is very easy.
What needs improvement?
Technical support is lacking post-sale.
The modification of firmware could be improved.
We find that the maintenance process could be a lot better.
The solution is more expensive than other options on the market.
For how long have I used the solution?
We haven't been using the solution for too long at this point. It's been about four months or so.
What do I think about the stability of the solution?
The stability has been good. It offers good performance and doesn't seem to be buggy. There aren't glitches. It doesn't crash or freeze. It's reliable.
What do I think about the scalability of the solution?
The solution is scalable. This is especially true for the cloud deployment model. There really isn't anything holding you back if you use that version.
We have around 100 people on the solution currently. 60 to 70 of those are technical users.
We do plan to keep using Splunk.
How are customer service and technical support?
Technical support services are lacking, especially after you buy the product. They aren't as helpful or responsive as we need them to be. However, when we do reach them, they are good and they help.
Which solution did I use previously and why did I switch?
I have used McAfee Nitro in the past and IBM QRadar as well.
How was the initial setup?
The initial setup is not complex. It's very straightforward. In fact, it's far easier to install than other log tools on the market. A company shouldn't have any issues with the process.
That said, I did not work on the installation myself. Other people at the company handled that aspect of the process.
The maintenance process could be better. It's a bit difficult once the deployment is done. We need about five people for maintenance tasks.
What's my experience with pricing, setup cost, and licensing?
When you compare the services and features, the pricing is reasonable. That said, if you compare Splunk to other options on the market, it is more expensive.
What other advice do I have?
As we recently purchased the solution, we are using the latest version right now.
I would recommend the solution to other users.
I would rate the solution at an eight out of ten. If the solution offered a better price and better support services, I would likely rate it higher. However, for the most part, we have been satisfied with the product and its capabilities.
Which deployment model are you using for this solution?
On-premises

Powerful programming language and search capability, but it is expensive and the vendor is inflexible
Pros and Cons
- "What I really like is that even if you have already collected the data, you can extract fields and can build searches."
- "I would like to see more SIEM functionality and a better ticket tool."
What is our primary use case?
My reason for implementing it was just to learn more about the product. I wanted to learn about the Splunk programming language, how to pipe searches, add logs, verify the logs, create fields, extract data into fields, build dashboards, and to get hands-on experience with the product.
What is most valuable?
The Splunk programming language allows you to pipe searches into another searches.
What I really like is that even if you have already collected the data, you can extract data and add fields which improves building searches. This is not the case with Elasticsearch, where this needs to be done upfront.
What needs improvement?
I really dislike how Splunk sales and partner manager behaves. I have faced several sales model and partnership changes. Also, the last time I wanted to by a license ro built a SIEM solution, they had removed the ability to purchase a splunk subscription or license from their website. In the past, there was a web page calculator it was possible to by online, but now it instructs to contact sales.
The free version is limited to 500 megabytes and there is no alerting. Due to the missing feature on the Splunk webpage, I have ask Splunk Sales to purchase a license like 1Gyte a day or a license for max 2500 Euro/year to use it as a test or development instance for myself. Asking Splunk for a quote willing to pay for Splunk license to learn and to get used to the product, Splunk didn't get it managed to offer my a license neither arranging the partnership paperwork I have ask for. Sales people from Splunk where calling, each time after I left my details on ther trial download page. I explained my experience and concerns about Splunk in the past. All excuses received and promises that someone will contact me to solve the issues faced in the past, was leading in excactly nothing. Well Done Splunk.
Inflexible and expensive and I do not have much faith in the people working there because if someone is asking for a test environment and is willing to spend up to €2,500 a year, I can't understand why they are unable to provide a license. This could be a lost opportunity because they are not able to onboard a potential new partner.
They definitely need to boost their sales and partner program because it changes to often, where they are dropping partners and it is difficult to get in contact with somebody. This is something that needs to be improved.
I would like to see more SIEM functionality and embedded moduled such a ticket tool to make a end to end SIEM.
For how long have I used the solution?
I have been using Splunk for a few weeks.
What do I think about the scalability of the solution?
As I was using a test environment, I can't comment on scalability. It was just myself and a colleague who was using it as a test instance.
How are customer service and technical support?
I have not been in contact with technical support.
Which solution did I use previously and why did I switch?
I have worked a little bit with Elasticsearch. I also have an instance of SIEMonster running, and I'm trying to get used to it. I found that Splunk provided a good benefit compared to Elasticsearch.
With Elasticsearch, if you have already inserted the data then it's gone because you need to do the pre-filtering. Once you've inserted or ingested the raw data, using Logstash, for example, you are no longer able to build the fields such as IP address, hostname, username, and the other fields that you want to export. This unsorted, raw data that you have is really a drawback for Elasticsearch and some other products. This is something from Splunk that I consider to be a heavy feature, where you can just insert data and ingest it later on.
How was the initial setup?
really fast and easy to install a test instance.
What's my experience with pricing, setup cost, and licensing?
The pricing model is expensive and could lead into a budget nightmare based on the amount of data.
A better pricing plan would be an improvement.
Which other solutions did I evaluate?
I have done some research on LogRhythm, IBM QRadar, and ArcSight, but I don't have any hands-on experience yet.
I did a comparison for a customer two weeks ago and the outcome of my comparison was SIEMonster, effortable price model, even though it's a niche player, it's quite powerful. I also provided Splunk as a recommendation because it is a market leader, really powerful, and really good to use. I also recommended LogRhythm; it is also expensive but it's also really powerful, and the feedback of customers is really good.
With respect to Splunk, I would recommend it but when a customer is budget-driven then Splunk is not the solution. Money shouldn't be the question.
What other advice do I have?
This is a solution that I could recommend for somebody who wants a really powerful product. It is not an end to end orchestrated SIEM yet.
This is a product that I would generally recommend, although I would not do so if the customer is really budget-driven.
I would rate this solution a six out of ten.
Which deployment model are you using for this solution?
On-premises

The logging features are useful as are the dashboards and alerts
Pros and Cons
- "Splunk is a user-friendly solution."
- "In terms of the interface, it could include some improvements for the look and feel."
What is our primary use case?
We use Splunk on-premise. We mostly use it for log analysis and fraud detection. We are also testing using it in machine learning and other solutions. We have 10 people managing Splunk and we have approximately 150 people using the product in total.
How has it helped my organization?
With Splunk, we got more insights out of our data as it includes machine and secure data. It also has a logging attendance system and this helps to protect our resources from any attackers hacking system information at a granular level
What is most valuable?
The logging features are useful as are the dashboards and alerts in addition to the organization of data. It has options for creating dashboards and alerts. You can also create queries in the SQL language. Splunk is a user-friendly solution.
What needs improvement?
Index performance is a bit slow but this is partly due to the huge volumes of data for our industry within our environment This makes the index very large and inefficient in terms of performance. Performance could be improved to cater to this, however. We have also had problems with the compatibility between Splunk and other systems. We have previously been on 5.3 and migrated to 5.5. We are now planning to migrate to version 7.7. It has been difficult to find documentation about the compatibility with Linux. In terms of the interface, it could include some improvements for the look and feel.
For how long have I used the solution?
We have been using Splunk for one year in our infrastructure environment.
What do I think about the stability of the solution?
The users access the native cloud solution. So we are taking advantage of the native cloud solution provided, and by using the gentle scaling approach this has helped stability.
What do I think about the scalability of the solution?
We scaled up gradually from three processes up to five, and the performance is okay. So we used gentle scaling but this also helped stability.
How are customer service and technical support?
We have used Splunk tech support often. If we have a critical issue such as server down or frequently occurring issues they are always reliable and provide us with solutions to our problems. Technical support for Splunk is good.
How was the initial setup?
Setup is complex. We tried to cluster five indexes. This helped us migrate our data into the Splunk environment. We are using 20 applications which make use of this indexed data. The actual deployment took us about two to three weeks because of some problems getting the data into the system.
What about the implementation team?
We worked with a Splunk consultant who shadowed us to help ensure we performed the process correctly.
What's my experience with pricing, setup cost, and licensing?
Licencing occurs yearly. We now have a three-yearly support contract as of now. Licensing is a yearly, one-time cost.
Which other solutions did I evaluate?
We considered a few alternative products because the logging was faster. In the end, we decided to go to Splunk.
What other advice do I have?
I would definitely recommend Splunk. We will review performance within two years of our three-year contract and then decide at that point what other aspects we need to consider. I would rate Splunk 8 out of 10.
Which deployment model are you using for this solution?

Automation Specialist, Analytics at a computer software company with 10,001+ employees
Identifies data patterns and provides metrics and intelligence for business operations
Pros and Cons
- "Splunk can extract all kinds of data. There's no limitation on what kind of structured and unstructured data one needs to extract — it can access any kind of data, including machine-generated data."
- "I'd say I am happy with the technical support, not elated. They provide great support, but sometimes they don't have the answers that I need."
What is our primary use case?
I use Splunk on-and-off — I started with in-house projects, then moved up to commercial projects.
What is most valuable?
Splunk can extract all kinds of data. There's no limitation on what kind of structured and unstructured data one needs to extract — it can access any kind of data, including machine-generated data.
The ease of deploying the agent is great in Splunk. One can easily deploy the Universal Forwarder which can extract any amount of information and put it into an indexer. The flexibility of ingesting any kind of data is good with Splunk.
In regards to action-oriented tasks, If an alert is triggered where I have to perform a certain action in the form of executing a Python script or invigorating a PowerShell script — this is easy to do with Splunk.
The Splunkbase is great. There are thousands of apps that are already available, I can install those apps with full-connectivity and use them to extract any form of data. The community in the Splunkbase is also really strong.
The ease of integration with third-party tools is great. In the Splunkbase, there are so many apps that are easy to integrate with.
The user interface is really good. There is a machine learning toolkit — I like it a lot. They have use cases in place so that people with little experience in machine learning can go through these examples of use cases and gain a better understanding.
What needs improvement?
Sometimes we experience issues when formatting and configuring files; however, this is a very technical issue that's hard to explain.
When extracting the data or structuring the data in the right format, sometimes it becomes challenging. It's up to the user to understand the regex commands.
Our customers often complain that the price of Splunk is too high.
When Splunk is deployed on the cloud, there are certain considerations that cannot be met. Cloud-based configuration cannot be done by our Splunk admin team. It needs to be routed via a ticket. You don't have more control on the cloud from a configuration point of view, whereas, with on-premise, you are in control — you can define any configuration settings.
When you install on-premise, many types of configurations can be done but when Splunk is on the cloud, you're dependent on their specific configurations.
For how long have I used the solution?
I started using Splunk in 2018.
What do I think about the scalability of the solution?
The scalability is good. If you have the money, you can expand — it's volume-based, not instance-based.
How are customer service and technical support?
I'd say I am happy with the technical support, not elated. They provide great support, but sometimes they don't have the answers that I need. I've only ever raised two big support issues, and both times they haven't been about to fully resolve the issue. In the end, I had to figure it out myself.
What about the implementation team?
We have one or two engineers that take care of all maintenance-related issues. It really depends on the scale of your project. One of our projects required a huge deployment — we needed a huge team to match. If it's a small deployment, then two people are enough.
What's my experience with pricing, setup cost, and licensing?
Its cost model is dependent upon the amount of data used — how many GBs we extract in a day determines our price. The price is not dependent upon how many instances we installed in Splunk. I can install thousands of instances, but it will only charge me according to how many GBs I extract per day.
Overall, our customers complain that the price is too high.
What other advice do I have?
I would definitely recommend using Splunk. They have free learning models available. There are models available on their learning page where you can gain a better understanding of how to use Splunk. Within one month alone, you can at least understand how to operate Splunk, whereas, with other tools, it can take a lot of time to understand.
On a scale from one to ten, I would give Splunk a rating of nine. The only downside is the cost. Price is the only factor; sometimes, companies shy away from Splunk because of the price.

A complete solution that satisfies the needs of our clients, but it is complex to set up and use
Pros and Cons
- "It's the completeness of the solution that we like the most."
- "Our two main complaints are about the difficulty of the initial setup and the licensing model."
What is our primary use case?
We are a software development company and Splunk is one of the products that we have implemented for our clients. It is used for log analytics as well as the mobile SDK for checking the stability of mobile applications.
What is most valuable?
It's the completeness of the solution that we like the most. It has a solution for backend log analytics, but also one for mobile applications.
What needs improvement?
Our two main complaints are about the difficulty of the initial setup and the licensing model.
The billing model is a little bit complicated because you have to predict in advance how much data you'll have and how much storage you'll need. When you start, you don't really have those numbers but to get the licensing, you need them. It is only at that point that you'll know how much the product is going to cost you.
For how long have I used the solution?
I have been working with Splunk for more than five years.
What do I think about the stability of the solution?
There have been no issues in particular. What we are using has not been that heavy.
What do I think about the scalability of the solution?
We have not had any problems with respect to scalability.
How are customer service and technical support?
Based on when we have been in contact with them, I think that technical support was fine.
I'm not sure if they have different support models but I think it took a long time for them to respond. It may be a consequence of the support contract our client had with them.
How was the initial setup?
This is a complicated product to use and you need constant help to set it up. I really wish that it was easier to set up and use.
What about the implementation team?
We do not have any dedicated people who are working on Splunk, but we have a team of approximately 100 people that are responsible for the development of mobile applications, backend systems, DevOps, etc.
What's my experience with pricing, setup cost, and licensing?
I think that most of the log analytics solutions are expensive and I'm not sure if it's worth it. However, I wish that they were less expensive. I am not talking about a single product but rather, all of the ones that are in the domain of log analytics.
What other advice do I have?
Splunk is a good product but I would definitely tell people to analyze their requirements to see if Splunk fits their use case, or not. The licensing model is very complicated, so if there is a product that has a better licensing model then it would probably be good to start with that. Then, later on, if the product is not working well enough, then they can switch to Splunk. At that point, they will have knowledge of the data they are using and will understand the costs that they might incur while using it.
The only way that I would suggest somebody use this as their first solution is if they already had all of the data that is required to get a cost estimate.
I would rate this solution a seven out of ten.

Practice Head-CyberSecurity at a computer software company with 1,001-5,000 employees
Good support with an intuitive dashboard but the cost is too high
Pros and Cons
- "The most valuable aspect of the solution is the dashboard. It's very intuitive."
- "There are a lot of competitive products that are doing better than what Splunk is doing on the analytics side."
What is our primary use case?
Since we have an IT services company, we have been using Splunk for the deployment to the customer locations as well. Sometimes the customer will come back to us and say that we need to have a SIEM tool, and when we do the benchmarking, we'll do a couple of deployments on the Splunk side and at the customer's locations as well.
As an example use case, we deployed Splunk to a banking institution a few years ago. There the use case was basically this: the customer wanted to set up a security operation center, and they wanted to have a pretty large deployment in terms of the number of endpoints and number of switches and routers. There were many regional branch offices and they have data centers and therefore, many assets in terms of endpoints. They had 30% of their assets are running on the cloud and they needed a complete solution from an incident monitoring and management perspective. That's why we deployed Splunk.
They wanted to reduce the MTTR, and meantime resolution, and maintain detection. They didn't want to add more SOC analysts into their SOC as the organization scaled up. They have a plan to scale from 5,000 endpoints into 15-20,000 endpoints. They're very particular about deploying the SOC operation center.
Splunk has since acquired Phantom as a SOAR platform. Therefore, we have tried to manage the security automation using Phantom with the help of Splunk deployments. It helps us meet the customer's requirements.
How has it helped my organization?
In terms of support, we're able to get the right support at the right time. If there's a break or an appliance issue, they're are on top of it.
This is very important during large-scale deployments. It's not easy to address product-related issues or appliance-related issues, and the number of collectors or number of logs that come into the collector, and managing the collectors across the branch offices, across the corporate offices, etc. It is a cumbersome process for us. That's why it's integral that we get the right support at the right time - and they make this happen.
What is most valuable?
The most valuable aspect of the solution is the dashboard. It's very intuitive.
The reporting is excellent. The team and the SOC analyst are able to easily track the alerts and the correlation is very good compared to other SIEM tools.
What needs improvement?
There are a lot of competitive products that are doing better than what Splunk is doing on the analytics side.
The automation could be better. Typically, the issue that we face is that it has to go to the analytics engine, then goes to the automation engine, basically. Therefore, if there are no proper analytics, the SOAR module is going to be overloaded, and we are not able to get the expected result out from the SOAR module. If they improve the analytics, I think they'll be able to solve these issues very quickly.
The playbooks which they create and provide to premium users can improve a lot. They have to create a common platform wherein the end-customers like us can choose the playbooks, and automation playbooks readily available.
In terms of integration with the third-party tools, what we are seeing is that it's very limited compared to the competitive products. Competitive products have a lot of connectors and APIs that they have developed, and that's where the cloud integration, whether it is a public cloud or a private cloud integration comes in. There are a lot of limitations to this product compared to other products.
For how long have I used the solution?
In terms of Splunk, I've been working on it for more than three years in the current company. Prior to that, I worked with it at another company as well. In total, I have been using Splunk for close to six or seven years.
What do I think about the stability of the solution?
The solution is stable, however, sometimes in some of the collectors, we are facing a lot of issues. That said, overall, if you rate it from one to five, I would say in terms of stability, it will stand at a three.
What do I think about the scalability of the solution?
The scalability is perfectly fine. It's very awesome compared to all the other tools, as easily we can integrate with the log forwarding modules and the collector management appliances or modules. That aspect won't be a problem.
If you look at the SIEM as a market today, Splunk is expensive compared to other competitive products. I'm also into the SIEM evaluation in my current role. I've seen that there are many tools are coming up in the last one and half years. I have also seen many other mature tools that are available now. If you compare next-gen SIEM tools compared to the Splunk, it's expensive. Therefore, it's possible we may not use this in the future or expand on current usage.
How are customer service and technical support?
In terms of technical support, we don't have any issues, as the professional services which they have extended to us are very, very good. We're able to manage many of the critical issues with their support. I'd say we are definitely satisfied with the level of service provided.
How was the initial setup?
In terms of deployment, it's not so complex compared to the competitive products, however, we will be able to manage that deployment. We don't feel there's any problem on the deployment side. In that sense, I don't think deployment is a complex one when somebody going for Splunk as a tool.
How long it takes to deploy the solution depends on the size of the deployment, basically. Even a large deployment won't take more than a week. When I say deployment, I'm considering all the log collection, log management, and the curation of the incidents, and how incidents are created and routed properly according to prioritization.
What was our ROI?
In terms of ROI, for example, if you look at one of our customers today, they are managing close to 100 million events per day. If you look at a traditional SIEM with 100 million events, they need to manage this environment with at least 25 to 30 people. That's 30 security analysts that have to be there. However, when Splunk was deployed, a lot of automation was added on top of it, and today we are managing the same environment with Splunk with close to 15 people. In that sense, if you look at it that way, the ROI is between 30-40%.
What's my experience with pricing, setup cost, and licensing?
In terms of a comparison with the rest of the competition, the licensing cost would be, I would say, 30% higher than most.
Which other solutions did I evaluate?
Before choosing Splunk, we have evaluated QRadar and LogRhythm. QRadar is much more expensive. LogRhythm lacked reporting.
We ended up choosing Splunk due to the pricing and the reporting features. It also had the kind of scalability that was required. We felt it would help us in terms of positioning from both a cost perspective and an incident alert perspective.
What other advice do I have?
We're partners. We have a business relationship with Splunk.
We're using the latest version of the solution.
Overall, I would rate the solution at a seven out of ten.
I'd advise potential new users to ensure they do proper sizing before deploying the product. If it's a very large deployment, the number of endpoints will be quite sizeable. You need to figure out the correct number of endpoints as well as endpoint devices, switches, routers, etc.
It's also a good idea to look at use cases. Splunk is very strong in some use cases. It's important to look into deployment scenarios and check out the use cases before deploying anything.
My biggest takeaway after working with the solution is that the environment is very important. You need to be clear about the problem you are addressing and it takes a lot of planning at the outset.
Which deployment model are you using for this solution?
On-premises
