Hi shadow,
if ultrasurf is that program for free surfing then probably it uses SSL/TLS to connect to some remote proxy server.
Use Wireshark and see to what servers it connects(if they are not too many) and block them.
Or restrict access to HTTPS sites using a white list.
And... do some management work.  People should not be allowed to bring and use any software they like.
Reagards!
