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 consolidation of the logs and being able to manage the items we have coming in -- all in one product -- has really helped this company a lot."
"LogRhythm SIEM's automated response capabilities help organizations mitigate threats through alerts based on specific use cases and monitoring requirements."
"Quicker ability to troubleshoot the problem, find the problem, get it fixed, and get the customers back up and using our system."
"We get a vast amount of ROI from this solution. We get way more out of it than we put into it."
"LogRhythm really helps with our cybersecurity exposure because it gives us insights to make us more proactive versus reactive regarding events happening in our environment."
"I like LogRhythm's ease of use. The solution has improved compared to previous versions. It had many issues before, like integration, the console, creating reports, false positives, etc. The AI engine has made it stronger in the latest version."
"LogRhythm lights up when an event occurs; as opposed to just giving us everything, it will piece things together for you and let you know that you probably should look at this, providing the evidence and making qualifying or investigations a little bit quicker and allowing us to close down on remediation times."
"For me, the NERC compliance modules are probably the best thing, and the system monitors really pick up a lot for me, helping you get an eagle-eye view and then delve down granularly, and the ease of that is pretty amazing."
"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."
"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."
"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."
"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."
"Syslog-ng has a separate config file in addition to the core configuration."
 

Cons

"I would say that the information is out there somewhere, but they don't have the best support site. They just don't."
"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."
"It should be improved for automated setup and auto-configuration. There should be ease of integration and ease of setup."
"We would like to see a better base templates for reporting."
"It should have some more message monitoring features. It can also have some free message monitoring tools."
"I have had a lot of trouble with stability, perfect timing."
"In terms of blind spots, we are looking for more improvements since we don't have visibility over everything."
"One of the things I find that would be helpful is the GLPR information, to be able to understand what is actually being processed."
"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."
"There is room for improvement in terms of observability."
"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."
"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."
 

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."
"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."
"I have seen a measurable decrease in the mean time to detect and respond to threats. We went from not detecting them to detecting them. We can actually pick up what is anomalous in our network now."
"The license cost is around $10 per MPS."
"I think the tool is reasonably priced. There is a need to pay per year towards the licensing costs of the tool."
"I would rate the tool's pricing around eight out of ten."
"We did a five-year agreement. We pay close to a quarter of a million dollars for our solution."
"LogRhythm's licensing is based on MPS. There are some add-on features like advanced UEBA, the cloud component for advanced UEBA, and SIEM."
"Syslog-ng is open-source."
"Syslog-ng is a free open-source solution."
