Proton Mail

🇨🇭Proton

Proton Mail is an end-to-end encrypted email service founded in 2013 at CERN by scientists Andy Yen, Jason Stockman, and Wei Sun. Headquartered in Geneva, Switzerland, it uses zero-access encryption — meaning Proton itself cannot read your emails. All infrastructure is located in Switzerland (including a former military bunker under 1,000 meters of granite). Proton Mail is open source, independently audited, and serves 100+ million users across Proton's ecosystem.
