Proton AG software suite

Proton AG is a significant Swiss technology provider founded in 2014 by a team of scientists who met at CERN in Geneva. The brand was initially established as Proton Technologies AG with the launch of Proton Mail, a service designed to provide end-to-end encryption for email communication. Its primary mission revolves around digital privacy and security, operating under the strict privacy laws of Switzerland.

Over the years, the brand has expanded its ecosystem to include Proton VPN, Proton Drive, and Proton Calendar. The company maintains its own server hardware in highly secure Swiss locations, including a former military bunker, to ensure maximum data sovereignty. In a unique move for a tech company, Proton transitioned to a non-profit ownership model in 2024 to ensure its mission-driven approach remains protected from traditional corporate acquisition or hostile takeovers.
