Featured Reviews

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.
Syarul Idzuddin Adzmi - PeerSpot reviewer
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

"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."
"It allows us to automate a lot of things with a smaller team."
"LogRhythm has shown to us, to this point in time, that it has the capabilities of being able to deliver actionable intelligence to the security engineers and analysts."
"I would say the most valuable feature of LogRhythm is that it has built-in UEBA functionality, among other basic Windows packages."
"The AI Engine can take an event and correlate it into something else giving us meaningful context regarding what is going on. We integrated it in with our ticketing system, so if an alarm fires, it raises a ticket in our system."
"The major feature of this solution is its easy configuration which helps different team members to work on it effectively. This kind of feature is not available in other solutions because of a request for specialised schemes for configuration report extraction and searching. Another feature that I really admire is the significant improvement in the compliance in the auditing process by the solution. Our organisation-specific complaints require where the mailbox data needs to be forwarded, stored and searchable for a certain time period. This solution categorises data based on different types, which include cold, warm and hot data. These features allow faster and easier extraction of any data even if the event was occurring several years ago. I also like other features, especially user behaviour analysis and automation. If suddenly someone accesses your side or an unusual traffic is recorded from a user the solution flags it very effectively."
"In general, the visibility of events and advanced analysis of events are good."
"NextGen SIEM's best feature is how it presents logs."
"The initial setup of Nagios Log Server was easy and straightforward."
"The product is scalable."
"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

"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."
"The web and on-premise console interface should be the same instead of having a separate engine for each."
"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."
"We had a little bit of difficulty implementing a disaster recovery situation because it was leveraging only Microsoft native DNS and it wouldn't work with our Infoblox DNS deployment that we use in our environment. They've been working on that behind the scenes."
"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."
"I would like to see support added for Exchange 2016, and CheckPoint OPSec Lea."
"The product's stability needs improvement."
"Parsing is totally controlled by LogRhythm and they do not allow any partner or any third-party to handle this part and this is a key challenge on my end."
"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 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."
"The support could be better."
 

Pricing and Cost Advice

"I think the tool is reasonably priced. There is a need to pay per year towards the licensing costs of the tool."
"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 rate the pricing 4 out of 5. There are no additional costs to the standard licensing fees."
"Look for whatever will give you the most value. That's the main point. It is not one size fits all."
"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."
"It costs a great amount, but its pricing is competitive with some of the other vendors. For licensing and support, we pay about 20,000. There are no additional costs or anything like that."
"We have seen a measurable decrease in the mean time to detect and respond to threats. As it comes out new features and new releases, the window is becoming a lot narrower because you can pivot a lot more with the data. Therefore, the new features and enhancements are reducing that."
"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."
"We found the pricing to be quite affordable."
"For a single instance, the price is around $4,000."
"On a scale of one to ten, where one is expensive, and ten is cheap, I rate the pricing an eight or nine."
