We are having DNS Advantage Package
We are concerened DNS over https , Is it a Security concern for us ? can umbrella be bypassed ?
Mostly our client machines are MACOS ?
Kindly provide some inputs in this direction of DNS over https
Solved! Go to Solution.
I would imagine that when you block "Proxy/Anonymizer" content category that would apply to any operating system. This page has additional information, you can further block DoH by blocking "Newly seen domains".
And for DoT block 1.1.1.1 and 1.0.0.1 port 853.
You can enable the "Proxy/Anonymizer" category in the DNS policy to block DoH providers
