Merit Ronald - PeerSpot reviewer
Senior Software Engineer at Absa Bank Uganda
Centralized log insights have reduced investigation time and improve security response
One improvement I want to see in Graylog Enterprise is artificial intelligence to help us automatically identify unusual patterns and suggest possible causes. I also want to see more ready-made dashboards and alert templates for common security use cases to help us gain value from the platform faster after deployment. Lastly, I want to see improvements in handling very large volumes of data, especially after searching, and a more user-friendly log management system, particularly in large environments. I give Graylog Enterprise a 9 out of 10 because it has a limitation of a steep learning curve for new users due to the many configuration options. It takes considerable time to become comfortable with creating searches, dashboards, and alerts. Additionally, in very large environments with large volumes of logs, it requires careful planning, and its data retention is quite limited.

Tool consistently aids in effective threat detection and monitoring but could benefit from improved log source management and resource optimization
One major area for improvement in LogRhythm SIEM is the lack of volume measurement capability in terms of storage. There is currently no way to determine how much data is being consumed in terms of gigabytes, terabytes, or petabytes from particular devices or environments. This information is crucial for planning future storage needs and scalability. The system monitor (collector) agent has issues with resource consumption. Even when not actively collecting data, the agent continues to consume significant CPU and memory resources, which can be particularly problematic for small business environments with limited resources. LogRhythm SIEM could improve by adding more default device support. While they have good default settings for devices such as Palo Alto firewalls, custom log sources often require extensive work. Increasing the number of supported devices with built-in policies and functionality would reduce the need for custom work. Competitive SIEM tools often provide more comprehensive coverage for various devices and vendors.

Quotes from Members

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

Pros

"Graylog is worth the given effort."
"Real-time UDP/GELF logging and full text-based searching."
"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."
"I like the correlation and the alerting."
"Graylog is very handy."
"Message forwarding through the in-built module."
"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."
"The solution's most valuable feature is its new interface."
"LogRhythm's GUI is easy to explore, and we also like other features, such as its integration with other security solutions, log correlation, and the deployment of use cases."
"This solution has been almost like a transformative change in how we detect and then respond to incidence."
"Everyone I have worked with knows their stuff, which is great."
"The correlation engine is extremely valuable because it uses machine learning to process information from the central manager and identifies issues in the network."
"Their customer support is friendly and willing to help."
"It has helped us centralize and have better visibility into devices on our network. We are better able to respond to threats in a timely manner."
"We should be able to response to threats and gain visibility into our environment that we don't currently have."
"LogRhythm NextGen SIEM is customizable, simple to manage, and there are many features, and the solution does not require an expert to be able to use it, anyone can use it."
 

Cons

"Elasticsearch recommendations for tuning could be better. 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."
"I would like to see some kind of visualization included in Graylog. The report is plain, they could be improved."
"The area in Graylog that needs to be improved or enhanced would be the integrations."
"More customization is always useful."
"Lacks sufficient documentation."
"The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."
"The support from the Graylog community is helpful, but they can do better."
"The problem was with the complexity and the cost to add extensions."
"The largest room for improvement would be inside the web platform, being able to have a longer log live time."
"The installation was a bit complex because we are running a virtual infrastructure."
"The biggest thing that I think needs improvement is reporting in the Web Console."
"I have Windows administrators who will remove the agent when they think that that's what's fouling up their upgrade or their install or their reconfiguration, etc. The first thing they do is to turn off the antivirus, turn down the firewall, and take off anything else. They don't realize that the LogRhythm agent is just sitting there monitoring. Most antivirus products have application protection features built-in where, if I'm an admin on a box, I can't uninstall antivirus. I need to have to the antivirus admin password to do that."
"The security playbook could be pre-defined and available to other analysts with similar security issues."
"I have had a lot of trouble with stability, perfect timing."
"Stability has probably been one area where Health Checks have not been great with the product. We have been told that they are going to improve Health Checks on product, though we do struggle with them on a daily basis."
"After a year-and-a-half, we're not stable yet. Every time we think we're stable for a week or two, we wake up the next morning to another million logs backlogged somewhere."
 

Pricing and Cost Advice

"Having paid official support is wise for projects."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"It's open source and free. They have a paid version, but we never looked into that because we never needed the features of the paid version."
"I use the free version of Graylog."
"We're using the Community edition."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"I have seen a measurable decrease in the mean time to detect and respond to threats. We went from not detecting them to detecting them. We can actually pick up what is anomalous in our network now."
"We have seen a measurable decrease in the mean time to detect and respond to threats. As it comes out new features and new releases, the window is becoming a lot narrower because you can pivot a lot more with the data. Therefore, the new features and enhancements are reducing that."
"I think the tool is reasonably priced. There is a need to pay per year towards the licensing costs of the tool."
"LogRhythm's licensing is based on MPS. There are some add-on features like advanced UEBA, the cloud component for advanced UEBA, and SIEM."
"In the context of our country, the price of this solution is too high."
"I give the price a six out of ten."
"We did a five-year agreement. We pay close to a quarter of a million dollars for our solution."
"In comparison to the competition, they are more affordable. This allows us to do more with less."
