How to totally blocked psiphon/ultrasurf

Hi Guys,

Does anyone know how to totally blocked Psiphon? I already raised this issue to Sophos XG support, He sets ips maxpkts, QUIC, port blocking, etc. but still it bypasses the blocking. I have this issue for almost a year but until now it seems there is no solution even upgrading to the latest firmware. On the other UTM/NGFW brand/devices they can blocked Psiphon. I hope this issue soon be resolved.

  • Hi Keyur,


    Thanks for the link, actually I am thinking of push installation using active directory but this is only possible for PCs. How about mobile phones or EU that has no AD? Back to my question, Have you tried to create or block Psiphon using IPS custom signature/pattern?
