Is there anyway to eliminate all internet access using proxy servers?

[Kishor]

I love WFilter more each day and it's become helpful in combatting the number of viruses that get thru by eliminating access to sites.



However, it has come to my attention that a few of our more wise employees are using proxy servers to get to sites such as facebook that I've specifically blocked.

I used darkhide.com as a test and got right thru to facebook. It didn't even show facebook in the detailed web surfing report.



However, darkhide did show. One by one blocking of proxy servers isn't going to be any fun.

Darkhide is a web server which acts as a relay server to the real websites. You need to block this website to block its service.
