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."
"We now have a central point of monitoring for all potential threats."
"It's positively affected our overall rate of efficiency."
"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."
"The most valuable features would be the automation, reporting, and the support."
"I would rate the product a ten out of ten. The solution is very user-friendly and straightforward. The tool's report customization is interesting."
"What I found most valuable in LogRhythm NextGen SIEM is that it's user-friendly. I also like its dashboard, which shows all the logs and information I want to see."
"The most valuable feature of LogRhythm for me is the ability to correlate logs throughout many different log sources."
"The user interface is good."
 

Cons

"Graylog Security needs to incorporate security scorecards."
"Scalability misses the mark sometimes, especially when you have an integrated disaster recovery built into the solution."
"Sometimes, the tool fails to get the correlated events that triggered the alerts."
"There used to be the ability to create alarms based on message text that was included in LR Version 6.x that has been removed in LogRhythm 7.x, and on that, I would like to see it added back."
"The built-in functionality of the solution for NDR, SOAR, SIEM, and EDS has room for improvement."
"LogRhythm SIEM can improve its user interface. The current interface is quite complex and can be challenging to navigate. While it offers many valuable features, understanding how to access and utilize them efficiently takes time. Simplifying the client console's user interface would significantly enhance the user experience and make it more user-friendly."
"It will definitely help if the parsing side would be much easier, meaning it would be better if we could easily make adjustments on the parser, both on standard and non-standard log sources."
"We're still struggling to get a real return on it and finding something that isn't false noise."
"One area for improvement in LogRhythm NextGen SIEM is that it's a Windows-based tool, and I feel it should be on the Linux operating system instead. Another area for improvement in the tool is the UI. There should be minor changes in the UI to make it better, though I like the dashboards in LogRhythm NextGen SIEM."
 

Pricing and Cost Advice

"I rate the tool's pricing a one out of ten."
"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."
"Look closely at the cost of licensing of other products. This should include setups and the need for support services. I did a RFQ to 2 other vendors before choosing this product."
"I think the tool is reasonably priced. There is a need to pay per year towards the licensing costs of the tool."
"I would recommend talking to the rep. That's the biggest thing because they will know what questions to ask."
"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."
"Everything is expensive with LogRhythm, and you don't get anything for free."
"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."
