Cyber Security Engineer at Diyar United Company
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.

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

"It's reliable and the performance is good."
"NextGen SIEM's best feature is how it presents logs."
"What I found most valuable in LogRhythm NextGen SIEM is that it's user-friendly. I also like its dashboard, which shows all the logs and information I want to see."
"It seems like it will scale easily with the way our environment is set up."
"LogRhythm NextGen SIEM is customizable, simple to manage, and there are many features. The solution does not require an expert to be able to use it, anyone can use it."
"Provides visibility into the network."
"As a SIEM, probably the best feature is that it can be tuned effectively. There are very few SIEMs out there that can be effectively tuned to provide you with meaningful information and not be overwhelmed."
"In terms of security, LogRhythm NextGen SIEM is great."
"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 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."
"The ability to extract and store the logs is the most valuable feature of syslog-ng."
"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 a separate config file in addition to the core configuration."
 

Cons

"I would like a more fuller implementation of STIX/TAXII so I can pull in some of the government lists without having to go implement a whole new STIX/TAXII platform."
"The responses provided by the cloud team are inefficient."
"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."
"Better integration with different services is needed, as there are quite a few platforms that we use that don't integrate very smoothly with LogRhythm."
"The integration is slightly difficult with other assets, like EDR technologies or firewalls."
"The solution is likely not the best option for a smaller organization."
"The software needs to work on its pricing."
"In terms of blind spots, we are looking for more improvements since we don't have visibility over everything."
"There is always the potential for additional integration and protocol extensions."
"There is room for improvement in terms of observability."
"In syslog-ng, I think a GUI would be beneficial. I am unsure if the premium module has a GUI to administer it."
"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."
"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."
 

Pricing and Cost Advice

"We work with French-speaking African countries, and it costs more than the average SIEM solution. Also, the pricing isn't too flexible. AlienVault, Splunk, and IBM QRadar are more suitable for customers on a tight budget."
"Look closely at the cost of licensing of other products. This should include setups and the need for support services. I did a RFQ to 2 other vendors before choosing this product."
"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."
"LogRhythm's licensing is based on MPS. There are some add-on features like advanced UEBA, the cloud component for advanced UEBA, and SIEM."
"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."
"We did a five-year agreement. We pay close to a quarter of a million dollars for our solution."
"In comparison to the competition, they are more affordable. This allows us to do more with less."
"The license cost is around $10 per MPS."
"Syslog-ng is open-source."
"Syslog-ng is a free open-source solution."
