Since 2006, Psiphon has provided open access to the internet for millions of citizens around the world.
Psiphon is a free and open source tool that utilizes VPN, SSH, and HTTP proxy technology for censorship circumvention. The Psiphon VPN essentially serves as a tunnel that enables you to circumvent censorship because you access resources on the internet through the non-censored tunnel that Psiphon provides.
OONI collaborated with Psiphon on developing an OONI Probe test that measures whether the Psiphon app works in a tested network. This test is available through the OONI Probe mobile and desktop apps.
We also collaborated on the Psiphon Data Engine, which integrates OONI measurements.
