Provides strong detection capabilities but requires improvements in parsing and stability
I cannot think of any specific features that LogRhythm SIEM can improve upon since it supports a wide variety of major vendors. However, they need to improve their parsing techniques; the tool should understand various devices and present data in a human-readable format. For example, if a personal Android mobile needs to be integrated, LogRhythm SIEM should be able to parse that data effectively. They also need to improve their database of supported devices to cover smaller vendors alongside the major players, allowing for better global reach and usability. I have noticed some problems with parsing errors, event mismatches, and data mismatching, so ensuring accurate parsing and continuous improvement according to device updates are my basic expectations as a detection engineer.

A scalable and affordable tool for monitoring data centers
Five engineers are needed for the maintenance of the product. I would definitely recommend the solution to those planning to use it. To increase the rating for the product, Nagios should offer remote support and offer more customization in reporting while making it easy for the customers to use it. Overall, I rate the solution an eight out of ten.

Quotes from Members

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

Pros

"It is a very good solution; it is very robust and very extensive."
"For me, the NERC compliance modules are probably the best thing, and the system monitors really pick up a lot for me, helping you get an eagle-eye view and then delve down granularly, and the ease of that is pretty amazing."
"Mostly for us the most valuable feature is its aggregation of all the logs into a single platform, and then doing the real-time monitoring based on that."
"As far as technical support, professional support, and overall organizational support, LogRhythm has probably been one of the best companies that I have worked with since I have been in technology."
"LogRhythm was really the first major product that we bought and the installation was awesome; it went as expected, moved along quickly, and provided value as soon as we were done with the installation."
"It's positively affected our overall rate of efficiency."
"For what it does, LogRhythm works pretty well."
"LogRhythm is a good product for what it is."
"The initial setup of Nagios Log Server was easy and straightforward."
"One of the most valuable features is the dashboard because the UI was effective and easy to use. The alert systems are good as well. We had no failovers and had high availability. We can search the queries fast as well in Nagios Log Server."
"The product is scalable."
"A great feature of the solution involves its internal portal."
 

Cons

"NextGen SIEM has separate rules for AI, advanced intelligence, and MP rules - it would be better to have a centralized way to write the rules and create alarms."
"Scalability has been a little tougher for us."
"We don't get much use out of this product because people around here consider it to be unreliable, and it's hard to do searches."
"I face stability issues every quarter that necessitate corrective maintenance."
"Sometimes the error-logging is not altogether helpful. For example, on an upgrade, a systems data processor, a Windows box, was throwing an error code like 1083. Then it just stopped and it died right out of the installer and nobody looked. We searched through Google and what it means is the Windows Firewall wasn't turned on so that it could create a rule for the product. Why wouldn't they bubble up that description so that I wouldn't have to call support and I could just know, "Okay, the firewall wasn't turned on. Turn it back on. Re-run the installer and keep going.""
"Granted, we haven't enabled the UEBA module, but we're forwarding all our proxy logs to LogRhythm and we have a really hard time pulling those proxy logs back out of LogRhythm. However, when we take LogRhythm and forward the same logs into somebody else's user-based analytics software, we get the majority of what we were missing... If we've got all our proxy logs and I go out to Google or Facebook or the like, we should be able to go in and pull that information out ten minutes later, but it's a big challenge to do that."
"The ability to customize certain features of the product."
"Functionality, ease of use. There are a few gotchas in the applications."
"As we are talking about a product which is open to the public, the pricing makes it challenging for us to profit off of its marketing."
"The configurations during initial setup could be improved. If they could be agentless, as in the case of the Ansible product, it would be better. I would like to be able to analyze the network bandwidth."
"The support could be better."
"The customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."
 

Pricing and Cost Advice

"The setup and licensing for small and medium size businesses is straightforward, though when it comes to the enterprise it pays to keep in mind the possibility for complications given all the extras and add-ons that may be required."
"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."
"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 would recommend talking to the rep. That's the biggest thing because they will know what questions to ask."
"I give the price a six out of ten."
"If you don't have your staff, absolutely look into the co-pilot and factor that into your cost evaluation."
"The solution has provided us with consistency and increased staff productivity through orchestrated automated work flows by at least 20 percent."
"On a scale of one to ten, where one is low, and ten is high, I rate the pricing between six and seven."
"We found the pricing to be quite affordable."
"On a scale of one to ten, where one is expensive, and ten is cheap, I rate the pricing an eight or nine."
"For a single instance, the price is around $4,000."
