Hi all,


Does anybody already try with success to block Psiphon ( ?

It's quite easy when psiphon is configured in VPN mode but how can I do that when VPN is not used ?


Thanks in advance for sharing.

Was it ever stated which category you need to decrypt?  I dont want to decrypt anything except for what it takes to stop Psiphon.

I could block the Psiphon, with a security policy denying in application "psiphon/unknown-tcp/ssh" and SSL decrypt and to avoid the AutoProxy I made this


Click Run, and type regedit to open the Registry Editor. Find and open HKEY_CURRENT_USER\Software\Psiphon3, and on the right side you will see SkipProxySettings. Set this value to 1 and Psiphon will not automatically configure the system proxy settings. 




additionally the unknown-udp application needs to be updated.
