Executive SummaryUpdated on Mar 15, 2026

Splunk Enterprise Security and Graylog Enterprise compete in the SIEM category. Splunk appears to have the upper hand with its extensive feature set and customizability.

Features: Splunk Enterprise Security offers comprehensive operational intelligence, rapid data availability from various sources, and flexible data handling through schema-on-read and search processing language. Additionally, it excels in log correlation, visualization, and threat detection with vast pre-defined use cases. Graylog Enterprise, while less feature-rich, efficiently handles log management, provides fast search capabilities, and integrates well with various systems while offering some data visualization options.

Room for Improvement: Splunk Enterprise Security could enhance its visualization capabilities, simplify its interface, and resolve performance-related issues. Users also wish for easier deployment and better user access management. Graylog Enterprise needs improvements in integration capabilities and more advanced visualization features to match its competitors.

Ease of Deployment and Customer Service: Splunk Enterprise Security offers diverse deployment models, including on-premises and cloud environments, catering to various organizational needs. However, its technical support receives mixed reviews in terms of response times and problem-solving effectiveness. Graylog Enterprise is easier to deploy, particularly for those with in-house expertise, as it primarily serves on-premises environments with a focus on straightforward operations but lacks extensive support channels.

Pricing and ROI: Splunk Enterprise Security is often seen as expensive due to its robust feature set and scalability, presenting challenges for small organizations. However, it's valued in large-scale environments. Graylog Enterprise, with its open-source model, presents a more economical choice for budget-conscious users, although it may demand more custom development to fulfill specific needs.

Log analysis has become clearer and faster but visualization and extensibility still need work

The problem was with the complexity and the cost to add extensions. We found this very expensive to buy another version with additional features. I think that Graylog Enterprise does not have customizable dashboards. I did not see them in Graylog Enterprise because most of the time we used the open source free version, which is limited. I think Graylog Enterprise should improve some things that they have in the paid version and perhaps provide users with a menu that gives examples of parsing logs and draws graphics so that people do not need to improve another system such as Grafana. This would be interesting. When it comes to functionalities, I found the log management in Graylog Enterprise acceptable. It is very simple to use and to collect logs. It has support for different protocols and different ports, and the sidecar is easy to use. However, in visualization, I think it needs to be much better.

Helps us detect cyber threats quickly and integrate multiple feeds effectively

Overall, the product is good, but when it comes to some infrastructure issues, we have to dig into more logs. There is no straightforward indication of an issue. Health check kind of dashboards are not available. More AI would help us, and more optimization, since security products run more queries. The AI module could suggest solutions, optimizing queries or workload balancing. If the product itself advises on running queries during peak times, it would be similar to what ChatGPT currently offers. We see quite a few issues on stability. Even last week, we faced something, and identifying bottlenecks is not easy. We need more SMEs, and there is no mechanism to tell us about indexer or search head issues. Self-monitoring dashboards could be beneficial. The technical support still requires more improvement. Often, primary support takes a lot of time and forwards most solutions to the engineering side. The primary support team has very limited knowledge to provide.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Graylog is very handy."

"Graylog's search functionality, alerting functionality, user management, and dashboards are useful."

"Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline."

"Real-time UDP/GELF logging and full text-based searching."

"We run a containerized microservices environment, and being able to set up streams and search for errors and anomalies across hundreds of containers is why a log aggregation platform like Graylog is valuable to us."

"We run a containerized microservices environment. Being able to set up streams and search for errors and anomalies across hundreds of containers is why a log aggregation platform like Graylog is valuable to us."

"The product does all the things it must do very well."

"The solution's most valuable feature is its new interface."

More Graylog Enterprise pros

"We can do things in minutes instead of days."

"It has been helping a lot of my clients with fast data mining and information propagation."

"I would assess the stability and reliability of Splunk Enterprise Security as generally good, with very few downtime, crashes, and performance issues."

"It is a one stop shop as a full monitoring and alerting solution for operations and application analysis for most of our back-end systems."

"Good for log collection and log management."

"We can present to our management in real time the security of the batch management for the PCs, security regarding the network equipment. We're currently working in the Azure Cloud project, so we can send any logs from the cloud to Splunk. We can monitor them and we can present to the managers and customers. It's a very good solution for reporting. We use Splunk for reporting and monitoring of any solution in the company."

"The solution has improved our organization by providing a comprehensive picture of any external threats to the operating system and improves asset control."

"The query functionality is very easy to use and fast to retrieve logs in comparison to other SIEM solutions."

More Splunk Enterprise Security pros

Cons

"Dashboards, stream alerts and parsing could be improved."

"Graylog doesn't have direct support for running the system inside of Kubernetes, so it can be challenging to fill in the gaps and set up containers in a way that is both performant and stable."

"There are many other applications in the market that influenced my rating reduction."

"The support from the Graylog community is helpful, but they can do better."

"I would like to see some kind of visualization included in Graylog. The report is plain, they could be improved."

"With technical support, you are on your own without an enterprise license."

"It would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."

"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."

More Graylog Enterprise cons

"The solution could improve by increasing the performance. We have run into problems when large amounts of data are processed."

"The GUI should be improved, in other words, the overall appearance."

"When deploying Enterprise Security, the biggest challenge or the most amount of work that you're going to spend time on is onboarding your data and getting it into a position that allows you to search it uniformly."

"We are waiting for Dashboard Studio to mature a little bit more. There are some things that we are using with Classic Dashboards which have not yet made it to Dashboard Studio. We are waiting for that."

"Splunk Enterprise Security can be improved mainly from the user interface regarding the visualizations."

"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."

"The implementation and the scanning of the logs can be difficult."

"DMC should be a little more intuitive with better dashboarding. Seeing the cause of data flow can be tough to track down."

More Splunk Enterprise Security cons

Pricing and Cost Advice

"Consider Enterprise support if you have atypical needs or setup requirements."

"Having paid official support is wise for projects."

"There is an open source version and an enterprise version. I wouldn't recommend the enterprise version, but as an open source solution, it is solid and works really well."

"I am using a community edition. I have not looked at the enterprise offering from Graylog."

"It's an open-source solution that can be used free of charge."

"You get a lot out-of-the-box with the non-enterprise version, so give it a try first."

"We're using the Community edition."

"Graylog is a free open-source solution. The free version has a capacity limitation of 2 GB daily, if you want to go above this you have to purchase a license."

More Graylog Enterprise pricing and cost advice

"While some clients find the cost of Splunk Enterprise Security to be on the higher end, its pricing is comparable to other SIEM solutions."

"The pricing can be better. We are already considering Elastic because Splunk is too expensive. You have to pay based on per-day ingestion. There should be a more flexible model for the use cases where one day you have a huge amount, and on other days, it is quite less."

"Licensing is a yearly, one-time cost."

"The solution is a little expensive."

"I am fine with the licensing, but in terms of the cost, it is expensive for the data that we have. We have an open discussion with our account rep about this."

"I believe that Splunk Enterprise Security is worth the price, but it is expensive."

"The price of this solution is expensive. However, it has great features. If you want a great solution you need to pay a price matching the features."

"It is possible to use a developer's license, which is up to 10GB per day of volume traffic, which is usually enough for most use cases."
