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

"We take in around 750 million logs a day. We have a lot of products and that would be a lot of different panes of glass that we would have to look through otherwise. By centralizing, we can triage and take steps much more quickly than if we tried to man that many interfaces that come with the products."
"Alarms are the most valuable feature. We also like the dashboard and how things are at your fingertips. The fact that we can now edit the report templates is going to be a great thing."
"It's reliable and the performance is good."
"As a healthcare company, what we use it for is compliance, then to protect our data from exaltation."
"Compliance reporting is another great feature of this product. It has built in reports right out of the box."
"NextGen SIEM's best feature is how it presents logs."
"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 correlation engine is extremely valuable because it uses machine learning to process information from the central manager and identifies issues in the network."
"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

"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."
"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."
"We've tried to work with a couple of engineering department guys there. We've called them and called them but we never hear anything back."
"The product's initial setup phase is pretty complex."
"In terms of blind spots, we are looking for more improvements since we don't have visibility over everything."
"We have gone through a few versions which has caused a lot of instability. We have logged a lot of hours with professional services."
"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 initial setup is not so easy because it is quite a process."
"Security Onion's user interface could be improved."
"The initial setup of the solution is a little bit difficult."
"The product is not easy to learn."
 

Pricing and Cost Advice

"I would rate the tool's pricing around eight out of ten."
"LogRhythm's pricing and licensing is extremely competitive and it's one of the top three reasons we continue to invest in the platform."
"In the context of our country, the price of this solution is too high."
"On a scale of one to ten, where one is low, and ten is high, I rate the pricing between six and seven."
"If you don't have your staff, absolutely look into the co-pilot and factor that into your cost evaluation."
"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."
"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 give the price a six out of ten."
"Security Onion is an open-source solution."
"It is an open-source solution."
"Security Onion is a free solution."
