Initially developed as an Apache HTTP Server module, it has since expanded to offer filtering capabilities across diverse platforms like Microsoft IIS and Nginx. Its event-based programming language facilitates HTTP traffic monitoring, logging, and real-time analysis, ensuring heightened security for web applications. Website owners can use it to keep their online spaces safe and secure at every moment, since the app is always on the lookout, analyzing all the traffic.
