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.

We currently do not use that feature. We currently have just an open-source release, not a premium release. My boss has indicated that he wants to buy a premium syslog-ng version next month. I think we can use other features of this tool in the future. In syslog-ng, I think a GUI would be beneficial. I am unsure if the premium module has a GUI to administer it.

Quotes from Members

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

Pros

"Currently, we are in the implementation phase. LogRhythm is better than QRadar from the point of view of collecting Windows events. It has a much higher view. You can enable monitoring by default."
"It's very easy to create the correlation rules with LogRhythm, and there are some advanced features like SIEM and UEBA, which are also very valuable."
"Support after implementation is probably the biggest."
"It's very easy to create the correlation rules with LogRhythm, and there are some advanced features like SIEM and UEBA, which are also very valuable."
"In terms of security, LogRhythm NextGen SIEM is great."
"NextGen SIEM's most valuable feature is its user-friendliness."
"I didn't know what to expect back in 2015 when we bought the product, but it's showing to be agile, scalable, and the people are very knowledgeable."
"For what it does, LogRhythm works pretty well."
"Syslog-ng provides easy access to all my logs. It helps me show managers and other clients precisely where an incident occurred. I also like it because you can integrate syslog-ng with multiple solutions to allow real-time monitoring."
"We chose syslog-ng because it is easy to install, easy to maintain, easy to update, and due to the fact that all data arrive in raw format, we can manipulate it as we want."
"The ability to extract and store the logs is the most valuable feature of syslog-ng."
"Syslog-ng has built-in features that we can use to create alerts for a SIEM solution. It isn't a true SIEM solution, but it's sufficient for the time being."
"Syslog-ng has a separate config file in addition to the core configuration."
"For us, the most valuable feature is the use of compound search for searching logs at a specific time, by a specific user, or specific behavior."
"What I appreciate most about syslog-ng is its configuration; its C-style config is much easier to understand, read, and write than other popular solutions such as syslog or rsyslog."
 

Cons

"Then, there is whole mention of hot versus warm and being able to keep data because SecondLook is terrible."
"The initial setup is not so easy because it is quite a process."
"It should be improved for automated setup and auto-configuration. There should be ease of integration and ease of setup."
"We have to use tech support pretty regularly and it is sometimes not very good."
"Sometimes, LogRhythm will parse the rule but perhaps it won't get every little detail out of the rule."
"When you get LogRhythm out-of-the-box, there are so many knobs to turn and so many things to configure and set up, that it's almost impossible to do it on your own, as an enterprise senior engineer."
"The software needs to work on its pricing."
"The solution is likely not the best option for a smaller organization."
"There is always the potential for additional integration and protocol extensions."
"There is room for improvement in terms of observability."
"The filtering has room for improvement."
"It's hard to find people who know how to use syslog-ng. I often find problems with configurations, and solutions aren't integrated correctly with syslog-ng. For example, there might be data with extra decimals, or the collector agents are incorrectly named. It isn't a problem with the solution; it's a lack of professionals."
"Syslog-ng has built-in features that we can use to create alerts for a SIEM solution. It isn't a true SIEM solution, but it's sufficient for the time being."
"In syslog-ng, I think a GUI would be beneficial. I am unsure if the premium module has a GUI to administer it."
 

Pricing and Cost Advice

"On a scale of one to ten, I'd rate the pricing of this solution as a seven - not too expensive but not cheap either. Regarding licensing costs, it varies depending on factors like being a partner or an end user, but there are no additional costs aside from standard licensing fees for the basic SIEM solution."
"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."
"I would recommend talking to the rep. That's the biggest thing because they will know what questions to ask."
"If you don't have your staff, absolutely look into the co-pilot and factor that into your cost evaluation."
"The product is inexpensive than other tools."
"We did a five-year agreement. We pay close to a quarter of a million dollars for our solution."
"In the context of our country, the price of this solution is too high."
"In comparison to the competition, they are more affordable. This allows us to do more with less."
"Syslog-ng is open-source."
"Syslog-ng is a free open-source solution."
