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

"In terms of security, LogRhythm NextGen SIEM is great."
"Its ability to work with all different sorts of log sources has been extremely valuable."
"As a healthcare company, what we use it for is compliance, then to protect our data from exaltation."
"Technical support is very helpful and responsive."
"Overall effectiveness is very good. I like how it is oriented to both analysts and technical support people. It's easily adopted by end users as much as by technologists."
"The dashboards in the LogRhythm SIEM really help us as a starting point. It gives us a starting point we can go to every day. We walk through several dashboards to see anomalous activity for further investigation."
"Our clients enjoy having one dashboard to monitor their environments in real time."
"LogRhythm NextGen SIEM covers all our primary security analysis needs. It makes it easier for us to analyze threats and improves our response times. It's a versatile platform that performs queries fast compared to other SIEM solutions."
"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."
"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

"We have run into problems with stability going through upgrade processes. Recently, we have been on the front edge of the upgrade path. When that happens we tend to run into issues either with certain functionality not working after the upgrades or stability issues because of the upgrades."
"The installation was a bit complex because we are running a virtual infrastructure."
"It should have some more message monitoring features. It can also have some free message monitoring tools."
"The web and on-premise console interface should be the same instead of having a separate engine for each."
"For our market, the solution is quite expensive. It would be ideal if they could work on and improve their existing pricing plans to help make it more affordable in our country."
"LogRhythm SIEM can improve its user interface. The current interface is quite complex and can be challenging to navigate. While it offers many valuable features, understanding how to access and utilize them efficiently takes time. Simplifying the client console's user interface would significantly enhance the user experience and make it more user-friendly."
"There used to be the ability to create alarms based on message text that was included in LR Version 6.x that has been removed in LogRhythm 7.x, and on that, I would like to see it added back."
"The solution is likely not the best option for a smaller organization."
"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."
"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."
"There is always the potential for additional integration and protocol extensions."
"There is room for improvement in terms of observability."
"The filtering has room for improvement."
 

Pricing and Cost Advice

"It is a very cost-effective solution."
"The license cost is around $10 per MPS."
"Everything is expensive with LogRhythm, and you don't get anything for free."
"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."
"NextGen SIEM's pricing is moderate."
"I give the price a six out of ten."
"I think the tool is reasonably priced. There is a need to pay per year towards the licensing costs of the tool."
"Syslog-ng is open-source."
"Syslog-ng is a free open-source solution."
