I rate syslog-ng 10 out of 10. It's free and easy to use. It has built-in tools that help us index the various logs sent to it. It's a solid log product. If you're looking for a SIEM solution, syslog-ng will work as a stopgap measure at beginning of the project. It can also work as an injector for a true SIEM solution. You can send all the logs to syslog-ng and forward all the data to the SIEM solution after you've cleaned up the data and got the pertinent information. It's a good front end for a commercial SIEM solution, which becomes more expensive as you load more data into it. I would highly recommend syslog-ng for that use case. However, if you lack the expertise, you might need to go with a cloud-based SIEM instead. You need some in-house expertise or an outside consultant to manage it and set it up.

Syslog is mainly used for network logs, and it can be configured to support a number of ports for an IP. From a scalability perspective, a front-end load balancer or other third-party elements can be used to route traffic to syslog. However, syslog will always look for the standard log format. If the format is not up to the standard syslog level, the load balancer will add its own IP to the log and forward it to syslog. To ensure integrity, the log should remain the same, without any changes to the server A IP. If there is a change in the login server A, the load balancer will add its own IP or hostname to the log and forward it to syslog. To address this issue, further investigation is needed to enable the product to overcome this scenario. We have 12 technicians supporting the platform.

Room for Improvement

Syslog-ng requires expertise for SIEM use cases as its filtering lacks depth, which could be enhanced with additional methods. Logging improvements are needed, including fine-tuning and level modification. There is a shortage of knowledgeable professionals leading to integration issues, such as misconfiguration and naming errors. Room for protocol extensions and observability improvements exists, alongside a desire for Kafka integration.

"There is room for improvement in terms of observability."
"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."
