Block Anonymous Proxies To Prevent Back Door Web Access 
Most Web Filters can be easily bypassed by surfers who have the know how of using an Anonymous Proxy. In order to block Anonymous Proxies, network administrators have to keep a database of known Proxy sites up to date. With 1000's of sites appearing each day, it is near impossible to keep ahead of the game.
Unlike most other web filters, Bloxx uses Tru-View Technology which performs real time contextual analysis of all sites not listed in their Database and will block any user who tries to visit a new Anonymous Proxy.
This is done dynamically and controlled by the administrator. With other filtering solutions administrators need to send a request to their Web filtering vendor to block the site.
For an added line of protection, even if the user gets access to the anonymous proxy site, Bloxx will continue to filter content and block access if required.
