Ultrasurf is a free software that enables users to visit any public web sites in the world safely and freely through a secure encrypted connection. It is a small file (approximately 1.2 MB), and will not install anything on your computer.

Ultrasurf is compatible with Windows, and runs on Internet Explorer or Firefox (click here to download the Firefox add-on). Certain anti-virus programs may prevent Ultrasurf from downloading. If you encounter this problem, you may need to temporarily disable your anti-virus software.

How does Ultrasurf work?
When a user launches Ultrasurf, the tool automatically discovers the best available proxy servers from our central server pool and connects the user to it via an encrypted tunnel. In this process, the user’s IP address is masked, and all their activities and communications are securely encrypted. This allows users to circumvent surveillance, bypass firewalls, and overcome blocking and censorship.
