DPI Tunnel: Bypass Internet Censorship

Free, open-source tool for accessing blocked websites & apps; encrypts traffic between user device and external server.

What is DPI Tunnel?

DPI Tunnel is a free, open-source anti-censorship tool developed by Psiphon that allows users to bypass internet censorship and access websites and apps that may be blocked in their country. It works by establishing an encrypted tunnel between the user's device and one of Psiphon's servers located outside of the censoring country.

When a user connects through DPI Tunnel, all of their device's traffic is securely encrypted and routed through Psiphon's server before reaching its final destination. This prevents network administrators from analyzing and filtering the user's traffic via deep packet inspection (DPI) and blocks. Only Psiphon's server can decrypt the traffic before passing it on to the desired website or app.

This allows users in censored regions to freely access news media, social platforms, communication apps like WhatsApp and Signal, and other sites that their governments attempt to restrict. The tool is designed to be easy to set up and use - users only need to install the app and connect with one click.

DPI Tunnel routes traffic through highly available proxy servers operated by Psiphon that are distributed globally. It incorporates multiple obfuscation techniques to avoid blocks and detection. The tool is free and open-source, available on Windows, Android, and iOS.
