Blocking PSIPHON through Koala Safe


I recently discovered my son had installed the program ‘Psiphon’ in order to try and get around the Koala Safe restrictions.

The only services listed under ‘Proxies & VPNs’ are Betternet and Ultrasurf. I have not seen anything within his usage history which I can identify as being an attempt by Psiphon to connect to the Psiphon servers, but I am not sure whether I would anyway.

Is it possible to add Psiphon to the list of VPNs? I presume there are many others as well which need to be blocked, as I can’t imagine Betternet and Ultrasurf are the only two that kids use.

Thanks in advance.
