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

"File Integrity Monitoring is really valuable because we have it set up on our core assets. This is one of the key features that I utilize. We also use it quite a lot for event management to do reporting."
"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."
"Technical support is very helpful and responsive."
"It has centralized monitoring for our security operations. Therefore, it improves our analysts' work."
"We have to be able to show the evidence, and LogRhythm does a great job of putting it forward and making it easy to create reports with nice looking dashboards, which show off what we are doing as a security program."
"LogRhythm SIEM has strong machine-learning capabilities with behavioral rules and analysis."
"It's very easy to create the correlation rules with LogRhythm, and there are some advanced features like SIEM and UEBA, which are also very valuable."
"We now have a central point of monitoring for all potential threats."
"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."
"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."
"The ability to extract and store the logs is the most valuable feature of syslog-ng."
"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."
"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

"Scalability misses the mark sometimes, especially when you have an integrated disaster recovery built into the solution."
"Move it to Linux. I would like to see it get off the SQL Server."
"I would really love to be able to take some of the data and not have to export it to a CSV file, so I can pull it into Excel to turn it into some other kind of graph."
"There is room for improvement with separate running sources or better integration."
"I have Windows administrators who will remove the agent when they think that that's what's fouling up their upgrade or their install or their reconfiguration, etc. The first thing they do is to turn off the antivirus, turn down the firewall, and take off anything else. They don't realize that the LogRhythm agent is just sitting there monitoring. Most antivirus products have application protection features built-in where, if I'm an admin on a box, I can't uninstall antivirus. I need to have to the antivirus admin password to do that."
"I would like to see APIs well-documented and public facing, so we can get to them all."
"The initial setup is not so easy because it is quite a process."
"NextGen SIEM has separate rules for AI, advanced intelligence, and MP rules - it would be better to have a centralized way to write the rules and create alarms."
"The filtering has room for improvement."
"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."
"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."
 

Pricing and Cost Advice

"The solution has provided us with consistency and increased staff productivity through orchestrated automated work flows by at least 20 percent."
"We work with French-speaking African countries, and it costs more than the average SIEM solution. Also, the pricing isn't too flexible. AlienVault, Splunk, and IBM QRadar are more suitable for customers on a tight budget."
"We did a five-year agreement. We pay close to a quarter of a million dollars for our solution."
"In the context of our country, the price of this solution is too high."
"Look for whatever will give you the most value. That's the main point. It is not one size fits all."
"I give the price a six out of ten."
"If you don't have your staff, absolutely look into the co-pilot and factor that into your cost evaluation."
"I would rate the pricing 4 out of 5. There are no additional costs to the standard licensing fees."
"Syslog-ng is open-source."
"Syslog-ng is a free open-source solution."
