We are planning to use Azure SignalR service for a mobile app to get real-time updates.

We have a requirement that all traffic on Azure go through a Web Application Firewall (Imperva WAF). Will SignalR Service work if the traffic goes through a WAF?

    Greetings,

    Application Gateway does support WebSocket out of the box. But WAF doesn't inspect WebSocket packets here as WAF is only for HTTP and HTTP(S) based traffic. You don't need any exclusions either in the WAF.
