Psiphon is a free, open-source internet censorship circumvention tool that uses a combination of VPN, SSH, and proxy technologies to provide access to the uncensored internet. Developed by the University of Toronto’s Citizen Lab, it works by tunneling your internet traffic through a secure network of constantly changing servers, making it difficult for censorship to block. It’s available on Android, Windows, and iOS and is widely used to access online content and services that are blocked in certain regions or on specific networks.
How it Works
Tunneling Technology: Psiphon creates a secure, private “tunnel” for your internet traffic, allowing you to bypass geographic restrictions or network-level blocks.
Protocol Switching: It automatically tries different communication protocols (VPN, SSH, and HTTP proxies) to find a reliable way to connect, even if one method is blocked.
Server Network: It uses a network of constantly changing servers to disguise your traffic and avoid censorship detection.
Key Features
Open-Source: The source code is publicly available, allowing for peer review and increased confidence in its security and design.
Censorship Circumvention: Its primary purpose is to help users bypass internet restrictions and access blocked websites and services.
Mobile Security: It provides secure, private browsing, especially on public Wi-Fi networks, by protecting your connection through its VPN capabilities.
