Azure SignalR and Security? No WAF?

Hey all,
My organization is looking at using Websockets with SignalR. We're very much used to using a web application firewall but ours and most do not seem to support websockets. Considering their nature, this makes sense to me.
We work with sensitive data and I'm concerned without inspecting traffic using our WAF, its going to be difficult to protect.
I'm not super familiar with websockets.
Are Websockets okay for applications working with sensitive data if we get proper security …
