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

"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 to investigate a particular period of time where you can analyze logs is its most valuable feature."
"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."
"We raise a ticket to LogRhythm, and they will give us their support."
"Its ability to work with all different sorts of log sources has been extremely valuable."
"The product is great for medium to large-scale organizations."
"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."
"Automations are very valuable. It provides the ability to automate some of our small use cases. The ability to integrate with other products that use an API is also very useful. LogRhythm has a plugin for it that we can connect and start to move down towards the path of a single pane of glass instead of having multiple or different tools."
"We use Security Onion for internal vulnerability assessment."
"Security Onion is the most mature solution in the market."
"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."
 

Cons

"Scalability-wise, it's not that great."
"Sometimes, the tool fails to get the correlated events that triggered the alerts."
"Technical support could use a little work in the terms of responding back. The feedback that we received is they do need a little more staff."
"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."
"My biggest issue - I know that they say they're doing it - is that the API-building is extremely important. They keep saying it's coming, it's coming. It's not coming fast enough. I don't care if they need to double their team size to get it out there quicker, the world is already in the cloud and we can't monitor it. That's a big problem for us. My boss keeps coming to me about it. That's an issue."
"The software needs to work on its pricing."
"One of the challenges of the SIEM for the LogRhythm 7 platform is the amount of time it takes to bring new log sources into the MDI."
"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."
"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

"On a scale of one to ten, where one is low, and ten is high, I rate the pricing between six and seven."
"On a scale of one to ten, I'd rate the pricing of this solution as a seven - not too expensive but not cheap either. Regarding licensing costs, it varies depending on factors like being a partner or an end user, but there are no additional costs aside from standard licensing fees for the basic SIEM solution."
"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."
"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."
"It is a very cost-effective solution."
"We work with French-speaking African countries, and it costs more than the average SIEM solution. Also, the pricing isn't too flexible. AlienVault, Splunk, and IBM QRadar are more suitable for customers on a tight budget."
"I would recommend talking to the rep. That's the biggest thing because they will know what questions to ask."
"It is an open-source solution."
"Security Onion is a free solution."
"Security Onion is an open-source solution."
