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.

Has ensured compliance by centralizing log data and supporting secure connections
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

"LogRhythm improves our organization by giving us insight into user activity and potential security threats, and our mean time to detect and respond has really improved with LogRhythm."
"LogRhythm's GUI is easy to explore, and we also like other features, such as its integration with other security solutions, log correlation, and the deployment of use cases."
"The LogRhythm support system is phenomenal."
"I would recommend LogRhythm."
"The security operation center is excellent."
"As a security organization, our challenges are discovering where our data is at, most times, and protecting it, and just having everything in a single space has been very helpful."
"Going from a third-party vendor to an in-house solution, such as the LogRhythm solution, has given us visibility into the entire organization, compared to the limitations, based on budget and whatnot, from a third-party vendor."
"While the cost is high, the security provided is quite good, and for those who can afford it, they will pay for the peace of mind."
"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."
"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."
"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."
"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."
"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."
"The ability to extract and store the logs is the most valuable feature of syslog-ng."
 

Cons

"Sometimes the error-logging is not altogether helpful. There have been many times where I've been disappointed, where I'll ramp an agent up to Verbose and it will say, "LogRhythm critical error, the agent won't bind to a NIC," or the like, and I end up with no really actionable or identifiable information coming in, even though I've ramped up the logging level."
"At times it gets a little clunky, or resource-intensive, but it works."
"Better integration with different services is needed, as there are quite a few platforms that we use that do not integrate very smoothly with LogRhythm."
"Report-building is in Crystal Reports and has a limitation."
"I do think there is room for improvement because the system is still running on the Windows Server platform. The problem with running on Windows is that it is not that good for scaling and providing for big deployment environments."
"Key challenges are our users and network."
"My biggest challenge always come back to log sources."
"Technical support could use a little work in the terms of responding back. The feedback that we received is they do need a little more staff."
"There is always the potential for additional integration and protocol extensions."
"There is room for improvement in terms of observability."
"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."
"The filtering has room for improvement."
"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

"I give the price a six out of ten."
"I would rate the pricing 4 out of 5. There are no additional costs to the standard licensing fees."
"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."
"On a scale of one to ten, where one is low, and ten is high, I rate the pricing between six and seven."
"The license cost is around $10 per MPS."
"LogRhythm's licensing is based on MPS. There are some add-on features like advanced UEBA, the cloud component for advanced UEBA, and SIEM."
"Everything is expensive with LogRhythm, and you don't get anything for free."
"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."
"Syslog-ng is a free open-source solution."
"Syslog-ng is open-source."
