DNS over HTTPS - DoH


Will ZIA be able to detect, and potentially block, DNS reguests over HTTPS?


DoH is great from a privacy point of view, but I think we can run into problems in the corporations if the browsers are asking the wrong DNS servers…

It’s just an HTTPS request so you can block the request if you know the URL or IP address.

Yes. Mozilla Firefox will detect Shift and disable DOH.
