An excellent tool for ensuring your anonymity on the Internet and solving the problem of access (from a secure tunnel) to any blocked sites.
The utility uses VPN, SSH and HTTP proxy technologies. Psiphon is the best tool for accessing the Internet and will protect you from hacked accounts and stolen passwords no matter what network you are connected to. Psiphon will automatically 'learn' about new servers and thus increase your chances of circumventing censorship.
Psiphon is an open source project.
A distinctive feature of this program is the ability to use both proxy servers (anonymizers) and "tunneling" (VPN) to achieve anonymity, switching between them with one click of the mouse.
