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 gives us insight into our entire installation, where we are multiple sites, going as far as the East Coast to the Central West Coast."
"LogRhythm SIEM offers advanced features such as AI engine modules, machine learning, and threat intelligence integration, which help reduce false positives. Advanced analytics streamlines incident response processes, enabling incident responders to prioritize and automate alerts."
"When it comes to dealing with support, all my interactions have been great. Everyone has known what they're doing and have been quick to respond. They seem to always know the answer. I haven't stumped anybody yet."
"File Integrity Monitoring is really valuable because we have it set up on our core assets. This is one of the key features that I utilize. We also use it quite a lot for event management to do reporting."
"Its ability to work with all different sorts of log sources has been extremely valuable."
"We should be able to response to threats and gain visibility into our environment that we don't currently have."
"The artificial intelligence engine."
"Provides visibility into the network."
"The product is scalable."
"The initial setup of Nagios Log Server was easy and straightforward."
"A great feature of the solution involves its internal portal."
"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."
 

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."
"When we originally got LogRhythm, their tech support was fantastic, and I loved them. Now, we don't quite get as quick of a response. I've been disappointed in the more recent tech support. When you call in, they'll say that they will get you somebody, and you'll finally get someone who will contact you back a day or so later. Whereas before, I would get help right away."
"I think they probably need to, because a lot of companies are having this cloud-first strategy, where anything that's new has to go into the cloud for some reason."
"I would really love to be able to take some of the data and not have to export it to a CSV file, so I can pull it into Excel to turn it into some other kind of graph."
"The product's stability needs improvement."
"We would like to see more things out of the console into the web UI. I guess this is what they are doing in 7.4."
"Sometimes, the tool fails to get the correlated events that triggered the alerts."
"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."
"The support could be better."
"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 customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."
 

Pricing and Cost Advice

"Look for whatever will give you the most value. That's the main point. It is not one size fits all."
"We did a five-year agreement. We pay close to a quarter of a million dollars for our solution."
"When it comes time to renew, they say, "This is what you are using. This is what we can do for you." So, they work with you on pricing."
"I give the price a six out of ten."
"I would rate the tool's pricing around eight out of ten."
"In the context of our country, the price of this solution is too high."
"LogRhythm's licensing is based on MPS. There are some add-on features like advanced UEBA, the cloud component for advanced UEBA, and SIEM."
"I think the tool is reasonably priced. There is a need to pay per year towards the licensing costs of the tool."
"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."
"We found the pricing to be quite affordable."
