SV
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

"The fact we're able to create customized monitoring reports that extract info from event logs helps us a lot."
"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."
"Regarding meeting those goals, in the last two months that we've had LogRhythm it's been very good."
"LogRhythm has shown to us, to this point in time, that it has the capabilities of being able to deliver actionable intelligence to the security engineers and analysts."
"It allows us to automate a lot of things with a smaller team."
"SOAR is integrated with the dashboard that we use for threat management. Because it's all integrated, it is useful for us when we deploy something on-prem."
"Our security program's maturity has been transformational for my staff."
"I have found the Advanced Intelligence Engine has provided the most value to us because we can customize alarms based on our requirements and have created hundreds of alarms that notify different people for different scenarios."
"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."
"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."
"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

"LogRhythm NextGen SIEM could improve by adding more applications for the banking sector. There are not any custom applications at this time."
"In the next release, I would certainly like to see more HIPAA compliance."
"A month or two will go by and everything will be fine, and all of a sudden, something breaks."
"The customer support system is time-consuming."
"One of the challenges of the SIEM for the LogRhythm 7 platform is the amount of time it takes to bring new log sources into the MDI."
"We have run into problems with stability going through upgrade processes. Recently, we have been on the front edge of the upgrade path."
"Right now you have to apply what they call RIM policies, Registry Integrity Monitoring policies, one agent at a time. If you have thousands of endpoint agents, you have to touch each one of those one at a time."
"I don't think the cloud model in LogRhythm is developed enough."
"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 always the potential for additional integration and protocol extensions."
"There is room for improvement in terms of observability."
"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."
"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

"On a scale of one to ten, where one is low, and ten is high, I rate the pricing between six and seven."
"I would rate the pricing 4 out of 5. There are no additional costs to the standard licensing fees."
"I would recommend that whatever sales quotes to them upfront, they will probably go up. Because they are probably going to outgrow that very quickly or once they start getting everything into it, they are going to have to move up anyway."
"In the context of our country, the price of this solution is too high."
"I give the price a six out of ten."
"LogRhythm's licensing is based on MPS. There are some add-on features like advanced UEBA, the cloud component for advanced UEBA, and SIEM."
"In comparison to the competition, they are more affordable. This allows us to do more with less."
"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."
"Syslog-ng is open-source."
"Syslog-ng is a free open-source solution."
