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

"LogRhythm has increased productivity because all the tools that we need are in the web UI, allowing us to find threats on our network fast and efficiently."
"Overall, it's had a very positive impact on our security posture."
"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."
"The most valuable feature of LogRhythm for me is the ability to correlate logs throughout many different log sources."
"LogRhythm's improved our organization by allowing all sorts of members of the organization to be able to access this data in a much easier way than they have been able to in the past."
"The most useful feature that I've found so far is the search function. I like all the different ways you're able to search through metadata and the different ways you're able to correlate or search through logs to find out what's going on."
"This solution has improved our organization in many different ways. The biggest benefit is being able to view all information in one dashboard instead of having to look at several different applications and dashboards. I can see information across our entire environment and every aspect of our network."
"Scalability is extremely great."
"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."
"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."
"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."
 

Cons

"The system monitor (collector) agent has issues with resource consumption. Even when not actively collecting data, the agent continues to consume significant CPU and memory resources, which can be particularly problematic for small business environments with limited resources."
"Just integration into our ticketing system, which we're using service now."
"When we originally got LogRhythm, their tech support was fantastic, and I loved them. Now, we don't quite get as quick of a response. I've been disappointed in the more recent tech support. When you call in, they'll say that they will get you somebody, and you'll finally get someone who will contact you back a day or so later. Whereas before, I would get help right away."
"There are other security technologies outside of this SIEM that should be inside of this SIEM."
"I face stability issues every quarter that necessitate corrective maintenance."
"My rating of eight out of 10 for LogRhythm is because, while I think the support is great, the solution is a little rough around the edges."
"LogRhythm NextGen SIEM is also not as good as IBM QRadar."
"A cleaner interface. I keep getting confused and forgetting where everything is."
"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."
"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."
"There is room for improvement in terms of observability."
 

Pricing and Cost Advice

"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."
"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."
"I think the tool is reasonably priced. There is a need to pay per year towards the licensing costs of the tool."
"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."
"NextGen SIEM's pricing is moderate."
"LogRhythm's licensing is based on MPS. There are some add-on features like advanced UEBA, the cloud component for advanced UEBA, and SIEM."
"I give the price a six out of ten."
"The license cost is around $10 per MPS."
"Syslog-ng is open-source."
"Syslog-ng is a free open-source solution."
