A great product with good indexing and data collection capabilities
Pros and Cons
- "The indexing and data collection are valuable."
- "Its search or filtering capability is nice, but it can be improved. It is currently a bit complicated, and it should be simplified. If we can write the search filter in a more simplified way, it would be better."
What is our primary use case?
I used it in the SOC environment to get logs, create dashboards, and filter out data.
What is most valuable?
The indexing and data collection are valuable.
What needs improvement?
Its search or filtering capability is nice, but it can be improved. It is currently a bit complicated, and it should be simplified. If we can write the search filter in a more simplified way, it would be better.

Cloud-ready, with forums and README tutorials that cover everything you need to know
Pros and Cons
- "Splunk would be my choice for the presentation layer because it comes with inbuilt reports and a dashboard that you can customize."
- "I haven't found a way for me to create my own plugins and integrate them into Splunk, but this isn't necessarily a limitation; it could simply be a lack of knowledge on my part."
What is our primary use case?
Splunk just acts as an extra presentation layer, and we tried it because of the plugins they have to try and get more logs into the environment.
What is most valuable?
Splunk would be my choice for the presentation layer because it comes with inbuilt reports and a dashboard that you can customize.
What needs improvement?
Aside from the 5GB limit on the community version, I believe it is the same as ELK. It's a useful tool, and nothing comes to mind right now.
I haven't found a way for me to create my own plugins and integrate them into Splunk, but this isn't necessarily a limitation; it could simply be a lack of knowledge on my part.
What do I think about the stability of the solution?
Splunk is a stable solution. I am very happy with the stability of Splunk.
What do I think about the scalability of the solution?
Splunk can be scaled to any environment. The way it's designed, it's cloud-ready, and it has a lot of performance, in-built indexing, and performance tuning options. Splunk is easily scalable.
How are customer service and support?
I am happy to report that I've never needed to contact technical support. The README tutorials and the existing forums provide me with practically everything I need. So far, I haven't had to do so. This should be a testament to the solution.
Which solution did I use previously and why did I switch?
We broaden the scope of IT governance and IT security.
We look at everything from SIEM to network management to endpoint protection, server protection, database protection, and anything else that can aid in visibility, policy enforcement, and monitoring.
Our organization is using a combination of Splunk and Elasticsearch. We get most of what we need from the ELK suite. ELK Stack is usually the primary focus.
ELK has the same inbuilt reports and dashboards that you can customize, but ELK is better for central logging and log aggregation. Once they've all been aggregated, you'll be able to run any kind of queries and APIs to query the logs on ELK and then use Splunk as a presentation layer for the consumers to use.
Security tools, in my opinion, are business tools and should be used by businesses rather than security engineers. I'm experimenting with a hybrid of the two, in which ELK serves as the engine for central logging and Splunk handles the presentation layer and aggregation of additional third-party logs from tools that might be difficult to integrate into ELK.
I would rate Elasticsearch a ten out of ten.
How was the initial setup?
It's a cloud-ready package. It has the same characteristics as ELK. From a deployment standpoint, I don't have any issues with it. The material is freely accessible to anyone who wishes to use it. There is a virtual machine option. You can get a virtual machine by downloading it. The deployment options are simply numerous, and it is up to the implementer.
It wasn't that difficult for me. There are no complaints from me. The material is present, and there are numerous options for deployment. It's relatively simple to go from zero to viewing data with Splunk. ELK is the same way. It is now up to the implementers and their environment to provide you with more data about it.
What's my experience with pricing, setup cost, and licensing?
They could improve their discounts. I think it's a good solution, and it's gaining a lot of traction, maybe they are recouping their R&D costs, Further reductions would be fantastic, and I believe that more and more people would flock to it.
Which other solutions did I evaluate?
We provide IT consulting services. Our customers occasionally ask us to assist them in locating specific solutions.
What other advice do I have?
I would recommend this solution to others who are interested in using this solution.
I would say the forums and READMEs provide more than enough information about Splunk. Most people struggle because they move too quickly through the implementation process. As long as you follow the guidelines, particularly the specifications for environment requirements and implementation methodology, these solutions should work out of the box.
Splunk is a very good solution, I would rate it a ten out of ten.

Responsive, and available, technical support, that is easy to install
Pros and Cons
- "It's better than IBM, in my opinion, because it's an independent entity."
- ". Having a trial version or more training on Splunk would be helpful."
What is our primary use case?
I use Splunk for testing purposes. It is used for school research and to learn how to use Splunk.
Splunk is mainly used for collecting logs and dashboards.
What is most valuable?
Splunk provides a free version so you can test it before purchasing. It's better than IBM, in my opinion, because it's an independent entity. IBM, for example, if you want to use EDR, and other features, you must use the features of other companies, such as ServiceNow and Jira.
I am still exploring the features provided in Splunk. As I have not used it for a long time, I don't have a clear vision of it.
What needs improvement?
As a student, I'd like to see more labs and things for students to test in order to learn.
Having a trial version or more training on Splunk would be helpful.
There is a free version, but it is insufficient for training and learning because it is a little bit difficult to work with, especially if you are a beginner. It's difficult to improve when you're just starting out with logs and SOC. As a result, we require a longer free version.
For how long have I used the solution?
Splunk is not used in my company. During my internship, I am being taught how to use it at school.
I have been using Splunk for one month.
What do I think about the stability of the solution?
I did not have any issues with the stability of Splunk. It was quite stable.
How are customer service and support?
There was technical assistance available. When you require assistance, they provide it, they will respond.
Which solution did I use previously and why did I switch?
We integrate Jira with QRadar which is helpful.
How was the initial setup?
The initial setup was simple because there is available support and tutorials.
What about the implementation team?
I completed the installation with the help of some friends, in the IT department.
What's my experience with pricing, setup cost, and licensing?
I'm only using the free version for the time being.
The cost is reasonable.
Splunk's costing is a little more difficult. The pricing method is complicated, and the way that costing is calculated in Splunk is a little more difficult.
When compared to QRadar, QRadar, it's simple to pay.
Which other solutions did I evaluate?
I did some research for a school project. I needed to compare it to Splunk and a few other tools. As a result, I'm not particularly interested in purchasing them.
What other advice do I have?
I would rate Splunk an eight out of ten.
Which deployment model are you using for this solution?

Effective machine learning, reliable, and responsive support
Pros and Cons
- "Splunk has machine learning which is a valuable feature."
- "The algorithms customization of Splunk could improve. They have limited algorithms for machine learning support. If they can allow the user to add more machine learning algorithms, such as the ability to choose the algorithm that a user might want. Additionally, they should provide the required libraries for those algorithms, and then analyzes the data for use."
What is our primary use case?
We are using Splunk for querying data from different sources.
What is most valuable?
Splunk has machine learning which is a valuable feature.
What needs improvement?
The algorithms customization of Splunk could improve. They have limited algorithms for machine learning support. If they can allow the user to add more machine learning algorithms, such as the ability to choose the algorithm that a user might want. Additionally, they should provide the required libraries for those algorithms, and then analyzes the data for use.
For how long have I used the solution?
I have used Splunk within the past 12 months.
What do I think about the stability of the solution?
Splunk is a stable solution.
How are customer service and support?
We have contacted the support and most of the reasons we have contact support has been project-related. For example, we want the APAs to work in a certain way or for certain fixes.
What other advice do I have?
I have been using Splunk for approximately

Integrates with every technology, easy to use, and good for analytics and cybersecurity
Pros and Cons
- "It is very easy to use and integrate. There are connectors for every technology."
- "The UI can be improved. Dashboards and reports can be better in terms of graphics."
What is our primary use case?
We work with Splunk. We use it for our own services, and we also integrate and resell Splunk. It is used for cyber security.
Different clients have different versions. They have Splunk Cloud and Splunk on-premises with different versions.
What is most valuable?
It is very easy to use and integrate. There are connectors for every technology.
What needs improvement?
The UI can be improved. Dashboards and reports can be better in terms of graphics.
For how long have I used the solution?
We have been using this solution for a few years. In 2016, we became a Splunk partner.
What do I think about the stability of the solution?
It is very stable.
What do I think about the scalability of the solution?
Its scalability is very good. We work with this platform for our own services. We use Splunk extensively, and we also offer it to our clients. We plan to increase its usage.
Our company has three offices. We have offices in Spain, Columbia, and Mexico. We have around 100 people, and about 50 people are working with Splunk. They all are focused on cyber security. They are security engineers or security specialists.
How are customer service and support?
I don't know about their support. I don't work with it much. On an activity level, I'm not so close to the platform. I'm the country manager, so I am a bit far from the operation.
Which solution did I use previously and why did I switch?
We tried to work with Exabeam for user behavior analytics, but we stopped it.
How was the initial setup?
Its setup is very easy, but we have been working with Splunk for a lot of years. We have all the certifications in Splunk, and we are a specialist in Splunk. So, for us, it is very easy to set it up and integrate it, but it might not be easy for other companies.
What other advice do I have?
Splunk is a very good platform for analytics and cybersecurity. We use it very extensively. It is very easy to use, and it is very stable and scalable.
I would rate it a nine out of 10.

Optimizes network security, straightforward to deploy, and can handle a large volume of data
Pros and Cons
- "The fact that Splunk is a platform and not just a SIEM solution is a key benefit."
- "The support that is included with the standard licensing fee is very bad."
What is our primary use case?
We are a solution provider and Splunk is one of the products that we distribute.
The primary use case is for SIEM and we have approximately 35 customers.
What is most valuable?
The fact that Splunk is a platform and not just a SIEM solution is a key benefit.
Our customers like that they can use Splunk to optimize their security.
What needs improvement?
The Splunk licensing model should be more flexible.
The support that is included with the standard licensing fee is very bad.
For how long have I used the solution?
We have been working with Splunk since 2017.
What do I think about the stability of the solution?
Stability-wise, it's perfect. We haven't had any problem with Splunk. It's good software.
What do I think about the scalability of the solution?
One of the key benefits and differences with this software is that the customer can scale up as much as they need to. Our largest Splunk customer is using between three and four petabytes of data per day.
How are customer service and support?
If you don't pay extra for technical support then it is very bad. If you pay extra for it, then the technical support is normal.
Which solution did I use previously and why did I switch?
I am familiar with other products and Splunk can handle much more data than IBM QRadar or any other competing product.
Direct competitors are more flexible when it comes to licensing.
How was the initial setup?
We have not had any problems installing Splunk.
For a standard case, it takes between one and two weeks to install correctly and deploy. This is for situations where the client has less than 50 gigabytes of data per day.
Problems during the implementation are typically due to something on the customer's side. For example, if the client does not have somebody that is responsible for the deployment, helping to speed up the various procedures, then this is a key problem for us.
What about the implementation team?
It takes two people to deploy and maintain.
What's my experience with pricing, setup cost, and licensing?
Splunk is not a cheap solution and the license is billed annually. The licensing model should be improved and the price should be lower, in general.
You can purchase additional technical support, which is much better than the support that is included.
What other advice do I have?
I would rate this solution an eight out of ten.
Which deployment model are you using for this solution?
On-premises
