I have managed to disable QUIC on Chrome and Edge for all users but still have the issue with Chrome, is it possible to disable ECH? Funny how MS implement blocking QUIC into their secure score and recommendations yet they can't get the web filter to work on Chrome...

We moved away from our Firewall doing web filtering for the pure reason people we're not protected at home... but now if they use Chrome they bypass all protection anyway.. feels like a somewhat step backwards

Yep, for GPO you'll need to use the latest ADMX or ADML file and the field is "EncryptedClientHelloEnabled", for intune it's in administrative templates

Enable TLS Encrypted ClientHello | Device

For Macs I believe you have to update the plist manifest values for:

EncryptedClientHelloEnabled
QuicAllowed

I'm no expert on Macs though.

Tested this to no avail!
Disables ECH and QUIC, reboot etc... the chrome:policy and Chrome:flags both show QUIC and ECH disabled yet the filter does not work.
Ensured history was cleared and but still no luck, works flawless on edge just nothing on Chrome
