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.

IT Infrastructure & Cloud Security Manager at Thux
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

"The GUI is very intuitive and the solution has good integration."
"We looked at LogRhythm, and LogRhythm seemed to have a lot of the stuff built in, canned already."
"From a security standpoint, it's the solution to have, in regards to LogRhythm."
"AXON has the ability to add and compare use cases."
"Overall, it's had a very positive impact on our security posture."
"We get a vast amount of ROI from this solution. We get way more out of it than we put into it."
"The content in the community is very helpful and useful for new users."
"It has far exceeded what I thought it was going to do for me in my job role."
"The ability to extract and store the logs is the most valuable feature of syslog-ng."
"Syslog-ng has a separate config file in addition to the core configuration."
"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 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."
"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."
"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."
 

Cons

"The product's stability needs improvement."
"There have been issues with the hardware which has resulted in the LRM going down a few times."
"I think they probably need to, because a lot of companies are having this cloud-first strategy, where anything that's new has to go into the cloud for some reason."
"A month or two will go by and everything will be fine, and all of a sudden, something breaks."
"We need to get better training for things like creating code and playlists. The way it's done now takes a long time."
"The log storage capacity should be increased."
"I would like to see more integration with more products that are out there within the same security field."
"There are other security technologies outside of this SIEM that should be inside of this SIEM. I can see in their roadmap that they're trying to address a lot of these things, and have these technologies built into the solution, because there is no point in going to another vendor or opening up a second window to obtain the data that you need."
"In syslog-ng, I think a GUI would be beneficial. I am unsure if the premium module has a GUI to administer it."
"There is room for improvement in terms of observability."
"There is always the potential for additional integration and protocol extensions."
"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."
"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."
 

Pricing and Cost Advice

"I would recommend talking to the rep. That's the biggest thing because they will know what questions to ask."
"The support which allows more customized to the environment when we are deploying new systems is called Professional Service and is very expensive. The technical annual support and there is an annual fee."
"I think the tool is reasonably priced. There is a need to pay per year towards the licensing costs of the tool."
"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."
"In comparison to the competition, they are more affordable. This allows us to do more with less."
"I would rate the tool's pricing around eight out of ten."
"The license cost is around $10 per MPS."
"We did a five-year agreement. We pay close to a quarter of a million dollars for our solution."
"Syslog-ng is open-source."
"Syslog-ng is a free open-source solution."
