Psiphon is a set of technologies that use a combination of secure communication and obfuscation to defeat network censorship systems. All Psiphon software is open source and designed to circumvent politically-motivated Internet censorship in countries where such censorship is extra-legally enforced.

Psiphon is not designed for strong anonymity, avoidance of copyright, or to allow users to share pirated software, unlicensed audiovisual material, or to access illegal content such as child pornography. We are governed by the laws of Canada, and abide by best practices in ensuring user safety and privacy. You can read our privacy policy here.

Psiphon inc develops and maintains the Psiphon codebase and builds and operates cloud-based content delivery systems for clients that include the British Broadcasting Corporation, Voice of America, Radio Free Asia, and Radio Farda as well as dozens of online newspapers journals and civil society groups worldwide.

Psiphon's award-winning architecture offers instant access to rich multimedia content without sacrificing user experience. We designed Psiphon as open source software so that developers can help make our software better, more secure, and easier to use. You can join our open source effort for Psiphon Web Proxy, and Psiphon for Windows and Psiphon Mobile.
