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.
Jörg Kippe - PeerSpot reviewer
A mature and affordable solution that is easy to install and easy to update
The product takes time to learn, it's not that easy. In the beginning we had a lot of questions. If you want to use such a tool in an real (industrial) environment, you have to ask how to get the network data. Can we do a full packet capture? Can we provide agents to our end systems? There are no simple solutions to these questions. It's a general problem when running such systems in an industrial environment.

Quotes from Members

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

Pros

"In terms of security, LogRhythm NextGen SIEM is great."
"The daily alerts allow me to quickly find security and operations issues which need to be addressed."
"The security operation center is excellent."
"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."
"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."
"I like LogRhythm's ease of use. The solution has improved compared to previous versions. It had many issues before, like integration, the console, creating reports, false positives, etc. The AI engine has made it stronger in the latest version."
"We now have a central point of monitoring for all potential threats."
"Even other products we have that feed into it, instead of having to watch all of them we only have to watch one. For example, we have CrowdStrike, so instead of having to pay attention that solution - because their dashboard doesn't really pop when an alarm comes up - we can see issues with the red on the LogRhythm alarm. That is very nice."
"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."
"Security Onion is the most mature solution in the market."
"We use Security Onion for internal vulnerability assessment."
 

Cons

"I would like to see APIs well-documented and public facing, so we can get to them all."
"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."
"There is room for improvement with separate running sources or better integration."
"We have run into problems with stability going through upgrade processes. Recently, we have been on the front edge of the upgrade path. When that happens we tend to run into issues either with certain functionality not working after the upgrades or stability issues because of the upgrades."
"I would like to see support added for Exchange 2016, and CheckPoint OPSec Lea."
"The built-in functionality of the solution for NDR, SOAR, SIEM, and EDS has room for improvement."
"We use Windows Event Forwarding to collect the logs from our Windows clients, and the logs get aggregated as one data source on that collector. Therefore, finding logs specific to one particular Windows system requires some creativity in how we search the SIEM."
"I would like to see our vulnerabilities counter. We will be using Tenable to fill that void right now."
"The initial setup of the solution is a little bit difficult."
"Security Onion's user interface could be improved."
"The product is not easy to learn."
 

Pricing and Cost Advice

"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 would rate the tool's pricing around eight out of ten."
"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 product is inexpensive than other tools."
"NextGen SIEM's pricing is moderate."
"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."
"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."
"Security Onion is an open-source solution."
"It is an open-source solution."
"Security Onion is a free solution."
