Why should I use Ultrasurf?

How does it work?
ANSWER: When a user launches Ultrasurf, the tool automatically discovers the best available proxy servers from our global server pool and connects the user to it via an encrypted tunnel. In this process, the user's IP address is hidden from the websites visited, and their communications are securely encrypted. This allows users to circumvent surveillance and overcome blocking and censorship.

Why Does Internet Freedom Matter?
ANSWER: According to Freedom House, in 43 countries around the world, the Internet is not free. Repressive governments censor content that, far from being harmful or nefarious, is vital to the workings of a healthy, pluralistic, and free society. Many of these states censor news and information, suppress dissenting voices and ideas, and monitor and imprison internet users. In many countries, governments may use their control of information to incite hatred against other groups, ethnicities, or nations, or to legitimize or conceal human rights abuses. States even suppress information about public health emergencies, like the SARS outbreak or the melamine scandal, with significant human consequences. The availability of circumvention tools empowers citizens to access, share, and report information that would otherwise be censored or inaccessible, thus helping mitigate human rights abuses in these countries.
