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.

IT Infrastructure & Cloud Security Manager at Thux
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 AI Engine can take an event and correlate it into something else giving us meaningful context regarding what is going on. We integrated it in with our ticketing system, so if an alarm fires, it raises a ticket in our system."
"Compliance reporting is another great feature of this product. It has built in reports right out of the box."
"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."
"The initial setup process is very user-friendly."
"The content in the community is very helpful and useful for new users."
"LogRhythm SIEM has some valuable features, including its ability to maintain backups of events and manage alerts separately through an engine that handles content and administration tasks."
"The daily alerts allow me to quickly find security and operations issues which need to be addressed."
"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."
"The ability to extract and store the logs is the most valuable feature of syslog-ng."
"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."
"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 a separate config file in addition to the core configuration."
"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."
"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."
 

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."
"My big thing is the easability. I don't like to go to two different systems. The fat client that you have to install to configure it, then the web console which is just for reporting and analysis. These features need to collapse, and it needs to be in a single solution. Going through the web solution in the future is the way to do it, because right now, it is a bit cumbersome."
"I don't think the cloud model in LogRhythm is developed enough."
"LogRhythm NextGen SIEM could improve by adding more applications for the banking sector. There are not any custom applications at this time."
"The customer support system is time-consuming."
"Parsing is totally controlled by LogRhythm and they do not allow any partner or any third-party to handle this part and this is a key challenge on my end."
"More help and assistance with some of the open source products, everything seems to be focused on Windows versus giving some guidance and some documentation on how to use it."
"The software needs to work on its pricing."
"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."
"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 always the potential for additional integration and protocol extensions."
"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

"In the context of our country, the price of this solution is too high."
"On a scale of one to ten, where one is low, and ten is high, I rate the pricing between six and seven."
"When it comes time to renew, they say, "This is what you are using. This is what we can do for you." So, they work with you on pricing."
"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."
"The nice thing about LogRhythm is you can either use the agents, getting a certain number of agents with your license depending on how you want to go, and those agents do a lot of cool things, or you can use CIS Log host, then you have like an unlimited number of them."
"NextGen SIEM's pricing is moderate."
"I would rate the tool's pricing around eight 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."
"Syslog-ng is open-source."
"Syslog-ng is a free open-source solution."
