SumitKumar20 - PeerSpot reviewer
Tool consistently aids in effective threat detection and monitoring but could benefit from improved log source management and resource optimization
One major area for improvement in LogRhythm SIEM is the lack of volume measurement capability in terms of storage. There is currently no way to determine how much data is being consumed in terms of gigabytes, terabytes, or petabytes from particular devices or environments. This information is crucial for planning future storage needs and scalability. The system monitor (collector) agent has issues with resource consumption. Even when not actively collecting data, the agent continues to consume significant CPU and memory resources, which can be particularly problematic for small business environments with limited resources. LogRhythm SIEM could improve by adding more default device support. While they have good default settings for devices such as Palo Alto firewalls, custom log sources often require extensive work. Increasing the number of supported devices with built-in policies and functionality would reduce the need for custom work. Competitive SIEM tools often provide more comprehensive coverage for various devices and vendors.

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

"The ability to investigate a particular period of time where you can analyze logs is its most valuable feature."
"The feature that makes it usable is the web interface."
"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."
"I like LogRhythm's ease of use. The solution has improved compared to previous versions. It had many issues before, like integration, the console, creating reports, false positives, etc. The AI engine has made it stronger in the latest version."
"AXON has the ability to add and compare use cases."
"The GUI is very intuitive and the solution has good integration."
"The most valuable feature is that we can alternate incident automations."
"Its ability to work with all different sorts of log sources has been extremely valuable."
"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."
"A great feature of the solution involves its internal portal."
"The product is scalable."
 

Cons

"It will definitely help if the parsing side would be much easier, meaning it would be better if we could easily make adjustments on the parser, both on standard and non-standard log sources."
"The built-in functionality of the solution for NDR, SOAR, SIEM, and EDS has room for improvement."
"It's not easy for someone new to the solution."
"I don't think the cloud model in LogRhythm is developed enough."
"The software needs to work on its pricing."
"LogRhythm SIEM needs improvement in data grouping and manipulation capabilities."
"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 thing we have mentioned to them before is that we'd like to be able to do searches, or drill-downs, directly from an alarm. When you click it and the Inspector tab slides out, that might be a good place to be able to click the host to search for the last 24 hours. I know the search is right there but it would be even nicer to just click that and then have an option to search something there."
"The support could be better."
"The customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."
"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."
"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."
 

Pricing and Cost Advice

"I would recommend talking to the rep. That's the biggest thing because they will know what questions to ask."
"I would rate the pricing 4 out of 5. There are no additional costs to the standard licensing fees."
"On a scale of one to ten, where one is low, and ten is high, I rate the pricing between six and seven."
"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 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."
"We did a five-year agreement. We pay close to a quarter of a million dollars for our solution."
"For a single instance, the price is around $4,000."
"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."
