Tony Zafiropoulos - PeerSpot reviewer
Aggregates logs in one place and helps to review data points
We tried Graylog Security, starting with their inexpensive open-source version. We tested it out and continued using it for a while. As for the main differences between Graylog Security and other vendors, some users might prefer cloud-based platforms over on-premises solutions. It isn't inherently cloud-native, but that might not matter much for some.
Mokhammad Rakhman - PeerSpot reviewer
User-friendly dashboard and machine learning capabilities improve threat hunting efficiency
LogRhythm SIEM has strong machine-learning capabilities with behavioral rules and analysis. The seamless integration for case management, along with a user-friendly dashboard user interface, makes tasks like threat hunting more efficient. Analytics and behavioral analysis help me save time with rule creation. Its scalability allows me to add components as needed. Overall, LogRhythm SIEM offers end-to-end visibility with a reasonable price.

Quotes from Members

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

Pros

"We use the solution to collect logs."
"The tool aggregates logs. We can see the logs in one place."
"One of the main features that I like about LogRhythm NextGen SIEM is that there are a lot of pre-built pieces. Like with our AV, we didn't have to tell it how to read the logs; they already had it pre-made. So, we essentially just had to follow their guide to get the logs imported in and set up some rules for it. We've only had to manually create the parsing rules for a few of our vendors so that we could interpret the logs correctly. Most of them had already been pre-created for us."
"LogRhythm's dashboard is very good compared to other SIEM solutions since it shows many details."
"We should be able to response to threats and gain visibility into our environment that we don't currently have."
"LogRhythm NextGen SIEM covers all our primary security analysis needs. It makes it easier for us to analyze threats and improves our response times. It's a versatile platform that performs queries fast compared to other SIEM solutions."
"Currently, we are in the implementation phase. LogRhythm is better than QRadar from the point of view of collecting Windows events. It has a much higher view. You can enable monitoring by default."
"The user interface is pretty good compared to other SIEM tools."
"The content in the community is very helpful and useful for new users."
"This solution has improved our organization in many different ways. The biggest benefit is being able to view all information in one dashboard instead of having to look at several different applications and dashboards. I can see information across our entire environment and every aspect of our network."
 

Cons

"Graylog Security needs to incorporate security scorecards."
"Sometimes, the tool fails to get the correlated events that triggered the alerts."
"The solution is likely not the best option for a smaller organization."
"I think there is room for improvement because the system is still running on the Windows Server platform. The problem with running on Windows is that it is not that good for scaling and providing for big deployment environments."
"The SOAR capabilities need improvements as they currently require programming knowledge."
"The console installation is an area with a shortcoming in the solution that needs improvement. If LogRhythm SIEM can offer a web console, it would be great."
"I would like to see APIs well-documented and public facing, so we can get to them all."
"Scalability-wise, it's not that great."
"I face stability issues every quarter that necessitate corrective maintenance."
 

Pricing and Cost Advice

"I rate the tool's pricing a one out of ten."
"If you don't have your staff, absolutely look into the co-pilot and factor that into your cost evaluation."
"When it comes time to renew, they say, "This is what you are using. This is what we can do for you." So, they work with you on pricing."
"LogRhythm's licensing is based on MPS. There are some add-on features like advanced UEBA, the cloud component for advanced UEBA, and SIEM."
"The nice thing about LogRhythm is you can either use the agents, getting a certain number of agents with your license depending on how you want to go, and those agents do a lot of cool things, or you can use CIS Log host, then you have like an unlimited number of them."
"The support which allows more customized to the environment when we are deploying new systems is called Professional Service and is very expensive. The technical annual support and there is an annual fee."
"The solution has provided us with consistency and increased staff productivity through orchestrated automated work flows by at least 20 percent."
"It is a very cost-effective solution."
"I would recommend talking to the rep. That's the biggest thing because they will know what questions to ask."
