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

"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."
"As a healthcare company, what we use it for is compliance, then to protect our data from exaltation."
"LogRhythm SIEM has strong machine-learning capabilities with behavioral rules and analysis."
"LogRhythm's GUI is easy to explore. We also like other features, such as its integration with other security solutions, log correlation, and the deployment of use cases."
"The dashboards in the LogRhythm SIEM really help us as a starting point. It gives us a starting point we can go to every day. We walk through several dashboards to see anomalous activity for further investigation."
"Overall effectiveness is very good. I like how it is oriented to both analysts and technical support people. It's easily adopted by end users as much as by technologists."
"The ability for me to go into the Web UI, and just learn what's going on in my environment."
"SOAR is integrated with the dashboard that we use for threat management. Because it's all integrated, it is useful for us when we deploy something on-prem."
"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."
"We use Security Onion for internal vulnerability assessment."
"Security Onion is the most mature solution in the market."
 

Cons

"Only area I can think of to improve on is the proof reading and using the guides before releasing them. Out the the 20+ guides I used one had issues with wrong information in it."
"We need to get better training for things like creating code and playlists. The way it's done now takes a long time."
"More help and assistance with some of the open source products, everything seems to be focused on Windows versus giving some guidance and some documentation on how to use it."
"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."
"For our market, the solution is quite expensive. It would be ideal if they could work on and improve their existing pricing plans to help make it more affordable in our country."
"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."
"We're still struggling to get a real return on it and finding something that isn't false noise."
"It's not easy for someone new to the solution."
"The product is not easy to learn."
"The initial setup of the solution is a little bit difficult."
"Security Onion's user interface could be improved."
 

Pricing and Cost Advice

"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."
"NextGen SIEM's pricing is moderate."
"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."
"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."
"In comparison to the competition, they are more affordable. This allows us to do more with less."
"I would recommend that whatever sales quotes to them upfront, they will probably go up. Because they are probably going to outgrow that very quickly or once they start getting everything into it, they are going to have to move up anyway."
"It is a very cost-effective solution."
"If you don't have your staff, absolutely look into the co-pilot and factor that into your cost evaluation."
"Security Onion is a free solution."
"Security Onion is an open-source solution."
"It is an open-source solution."
