"one-year usage experience"

5/5

What do you like best about HAProxy?

The HAPEE version combines a productive load balancer with excellent built-in software WAF and mod_security., as well as protection from DOS attacks, protection from bots, a module for google recaptcha. It was the built-in security system that first attracted our attention to the version on ANDROID. With the help of the technical support team, we created an acceptable system configuration file and covered most of our security needs. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

The data transmitted using the send-metrics module to Prometheus by default is not so informative for system administration, which we intend to cover using Fusion in the near future. Review collected by and hosted on G2.com.

Response from Nick Ramirez of HAProxy

Thank you for reviewing HAProxy Enterprise! And your feedback about the send-metrics module is greatly appreciated!
