Download UltraSurf

UltraSurf is a free, lightweight anti-censorship tool that lets you bypass internet firewalls and access blocked websites quickly and securely. Originally developed to help users in China circumvent the Great Firewall, it has grown to serve millions of users in countries with internet restrictions worldwide.

UltraSurf works by routing your web traffic through a network of secure proxy servers using encrypted tunnels, making it difficult for censorship systems to detect and block your connection. It integrates directly with Internet Explorer and can be used as a system-wide proxy for other browsers and applications.
