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

"One of the main features that I like about LogRhythm NextGen SIEM is that there are a lot of pre-built pieces. Like with our AV, we didn't have to tell it how to read the logs; they already had it pre-made. So, we essentially just had to follow their guide to get the logs imported in and set up some rules for it. We've only had to manually create the parsing rules for a few of our vendors so that we could interpret the logs correctly. Most of them had already been pre-created for us."
"It allows us to automate a lot of things with a smaller team."
"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."
"In terms of security, LogRhythm NextGen SIEM is great."
"The log analysis feature is valuable."
"Alarms are the most valuable feature. We also like the dashboard and how things are at your fingertips. The fact that we can now edit the report templates is going to be a great thing."
"The Web Console is my favorite. It enables me, at a glance, to see the health of the environments."
"I would say the most valuable feature of LogRhythm is that it has built-in UEBA functionality, among other basic Windows packages."
"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 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."
"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."
"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 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

"LogRhythm NextGen SIEM is currently based only on the Windows platform. This means that some of our customers have to purchase a Windows license elsewhere. If LogRhythm can move to a Linux platform or a proprietary platform, it would be very helpful."
"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."
"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.""
"Right now there is the concern about being able to gather all of the data into the system."
"We've had issues with scaling and local support."
"The security playbook could be pre-defined and available to other analysts with similar security issues."
"It will definitely help if the parsing side would be much easier, meaning it would be better if we could easily make adjustments on the parser, both on standard and non-standard log sources."
"LogRhythm's SOAR and NDR features don't stack up well against competitors. maybe integrating theme functionality as the other do. But in general, it's okay."
"There is always the potential for additional integration and protocol extensions."
"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."
"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."
"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

"Everything is expensive with LogRhythm, and you don't get anything for free."
"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."
"I would recommend talking to the rep. That's the biggest thing because they will know what questions to ask."
"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 pricing is very reasonable and accessible compared to other products in the market but I am not very sure about the exact licensing cost per year for our company."
"The support which allows more customized to the environment when we are deploying new systems is called Professional Service and is very expensive. The technical annual support and there is an annual fee."
"The license cost is around $10 per MPS."
"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."
"Syslog-ng is open-source."
"Syslog-ng is a free open-source solution."
