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 does a very good job of helping SOCs manage their workflows."
"We have seen a massive increase in the amount of data that we can collect, the type of things that we can see, the way we can look at logs, the way we can get alerts, and the way can create our own customer roles, which has allowed us to customize the work in our environment."
"The user interface is pretty good compared to other SIEM tools."
"It supports most standard log sources."
"LogRhythm SIEM offers advanced features such as AI engine modules, machine learning, and threat intelligence integration, which help reduce false positives. Advanced analytics streamlines incident response processes, enabling incident responders to prioritize and automate alerts."
"Its benefits are broad. The solution isn't necessarily made to do any one thing, but it can do anything you tell it to. It is able to tackle any different type or size of job."
"We raise a ticket to LogRhythm, and they will give us their support."
"In terms of security, LogRhythm NextGen SIEM is great."
"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."
"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."
"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."
"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."
 

Cons

"It should have some more message monitoring features. It can also have some free message monitoring tools."
"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."
"The reporting on the dashboard should be improved from a management perspective. It would be helpful if they adjusted the colors and the presentation to make things clearer and easier to read."
"Some of my customers have a very large need but refuse to go with LogRhythm SIEM due to its complexity and high resource intensity."
"I have probably submitted half a dozen log parser requests, and I keep finding more stuff that we need to keep an eye on that doesn't have a definition in LogRhythm."
"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."
"Sometimes the error-logging is not altogether helpful. For example, on an upgrade, a systems data processor, a Windows box, was throwing an error code like 1083. Then it just stopped and it died right out of the installer and nobody looked. We searched through Google and what it means is the Windows Firewall wasn't turned on so that it could create a rule for the product. Why wouldn't they bubble up that description so that I wouldn't have to call support and I could just know, "Okay, the firewall wasn't turned on. Turn it back on. Re-run the installer and keep going.""
"Sometimes, the tool fails to get the correlated events that triggered the alerts."
"In syslog-ng, I think a GUI would be beneficial. I am unsure if the premium module has a GUI to administer it."
"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."
"There is always the potential for additional integration and protocol extensions."
"There is room for improvement in terms of observability."
"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."
 

Pricing and Cost Advice

"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."
"Everything is expensive with LogRhythm, and you don't get anything for free."
"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 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."
"If you don't have your staff, absolutely look into the co-pilot and factor that into your cost evaluation."
"LogRhythm's pricing and licensing is extremely competitive and it's one of the top three reasons we continue to invest in the platform."
"I give the price a six out of ten."
"Syslog-ng is open-source."
"Syslog-ng is a free open-source solution."
