Web and Application Filterring (to block proxy)

Hi All / Support,

Kindly confirm if the proxy apps and site are capable to be blocked by Sophos XG 135. I tried this instruction https://community.sophos.com/kb/en-us/123619 but seems my users still can access restricted sites by using proxy (K Proxy) addons in Google Chrome web browser.

Can someone provide a guide on me maybe i missed something on my part. Many Thanks

Tophs

Hi,

you will need to enable https scanning and decrypt and install the CA on each device.

You will also need to ensure that you do not have firewall rules that have source as any -> any -> allow all services.

You will need to tick block QUIC on your firewall page.
