Psiphon is a web proxy designed to help Internet users securely bypass the content-filtering systems used to censor the internet. Psiphon was developed by the Citizen Lab at the University of Toronto, building upon previous generations of web proxy software systems, such as the “SafeWeb” and “Anonymizer” systems.
In 2008 Psiphon was spun off as a Canadian corporation that continues to develop advanced censorship circumvention systems and technologies. Psiphon maintains its research and development lab and computer network “red team” at The Citizen Lab, Munk Centre for International Studies, University of Toronto.
There are currently two branches of Psiphon development: psiphon open source, and a commercial version that includes the managed proxy cloud and proprietary anti-counter circumvention system.
Psiphon open-source’s recommended use is among private, trusted relationships that span censored and uncensored locations (such as those that exist among friends and family members, for example) rather than as an open public proxy. Traffic between clients and servers in the Psiphon system is encrypted using the https protocol. Released under the GNU General Public License, Psiphon open-source is free software.
