I have been a long-time user of Safeline, and I have seen its development and improvement step by step to the launch of the professional version. Safeline's security detection is very powerful, which is very different from any open-source WAF I have used before. The configuration is very simple and easy to understand, and it has excellent performance, is easy to deploy, and has a low false positive rate.
