Are webservers behind a WAF safe enough to be classed as trusted

Hi,

I am after some advise on a hub and spoke design idea.

If I have a hub that contains a firewall and a WAF where the WAF is forwarding traffic onto a webserver in a spoke virtual network. Would you then class that web server / virtual network as trusted and consider domain joining to make management easier?

Looking at reference designs, my understanding is that the hub vNet is treated as your un-trusted zone and then any spokes are trusted? Or would it be wise to have a separate DMZ spoke that is classed as untrusted?

Thanks

    @probi Firstly, apologies for the delay in responding here and any inconvenience this issue may have caused.
    Looking at reference designs, my understanding is that the hub vNet is treated as your un-trusted zone and then any spokes are trusted => that's true

    It's based on your design and you can perform the POC test and go through. For now design isn't recommend

    Hope this helps!
