UltraSurf is an anti-censorship instrument intended as a lightweight freeware program. It enables firewalls to be circumvented using proxies and uses privacy encryption protocols. Other apps include protecting your government WIFI security, hiding your IP address and communicating encrypted. UltraSurf discovers proxy servers from a range of servers worldwide when began and creates a link through an encrypted tunnel. The software runs from a hard drive or portable media, such as USB drive, memory card or CD, without installation, and after shutdown leaves no registry. Internet Explorer and Firefox are the browsers that UltraSurf is presently running through.
