ProtonVPN recently announced it was making all its VPN applications open source and simultaneously releasing security audits of its various VPN applications.
We’re happy to be the first VPN provider to open source apps on all platforms (Windows, macOS, Android, and iOS) and undergo an independent security audit. Transparency, ethics, and security are at the core of the Internet we want to build and the reason why we built ProtonVPN in the first place.
. . .
Making all of our applications open source is therefore a natural next step. As former CERN scientists, publication and peer review are a core part of our ethos. We are also publishing the results of independent security audits covering all of our software.
