Block Psiphon App

Hi,

Is there any way to block this psiphon app? is it needed ssldecrypt?

This app uses many apps (ike,ssh,ssl) so we can not block them. How do you block this app psiphon?

Hello,

You can create a security policy that has this application listed and set the policy to block.

Just make sure its higher in the list than ones that would allow it.

Regards,

@BigPalo,

The answer to this is that you need to be decrypting traffic to reliably block psiphon and have the application identify correctly. Outside of being able to decrypt the traffic, this app-id doesn't get matched reliably.
