Does anybody already try with success to block Psiphon (https://www.psiphon3.com) ?
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.

After opening a case, the answer is: Decryption enabled (blocking unsupported cypher-suite) + denying 'psiphon' application in security policy should be enough.
Need to be tested.

If you use some kind of web filtering, this should be able to block it on your network. I just checked the PAN-DB-URL and that url is:

URL filtering can't be used because after "installing" the psiphon client, you need to initiate connexion.
These connexions are based on SSL then no URL filtering ... 😞

I do not know how the client works so I cannot see the traffic for myself. However you should still be able to see the URL's eventhough the traffic is SSL. Perhaps a submission for application detection is in order?
Submit an application:
Hope this helps...

Just in case you do use URL filtering:
