Psiphon 3 block

Hi folks, could someone has ideia about block Psiphon 3, currently Sophos XG are not blocking it, even following the KB according Sophos support.

And the attendant told me that this is a known issue and the definitive solution will be on Sophos XG v. 18

 

Could someone has idea about it ? 

 

Cheers,

Carlos

  • Hi Carlos,

    the XG can and does block Psiphon 3. You need to follow the instructions in detail and ensure that the users cannot access any other firewall rule.

    You will need to manage your user access because a lot of sites are classified as NONE which are used as redirected sites from allowed connections.

    You will need to install then XG CA on all your user devices, without that you will not be able to block Psiphon 3. You will also need https scanning, web and application rules and limited ports in your firewall rules.
