Qualys WAF 2.0 New Feature

Jerome Clauzade

Last updated on: September 6, 2020

Qualys Web Application Firewall 2.0 (WAF) now supports multiple secure web applications (HTTPS) in the same cluster, through the Server Name Indication (SNI) extension of TLS protocol. Multiple TLS certificates could now be presented on the same WAF Cluster IP, making the configuration and the deployment of multiple secure websites easier and quicker.

With SNI support, the client is indicating to Qualys WAF which secured application it is attempting to connect at the beginning of the secured exchange.
