The world's most highly trafficked sites trust HAProxy as their frontline defense to a myriad of attacks. HAProxy users receive the benefits of SSL with less hardware while reducing the number of services exposed to the Internet.

We detect and stop DDoS, Brute Force and SQL/XSS attacks. With our advanced logging, we identify intrusions and assure protocol compliance.
