Proton Mail software

Proton Mail is a globally recognized end-to-end encrypted email service launched in 2014. It was developed by scientists who met at the European Organization for Nuclear Research (CERN) and was initially crowdfunded. The brand is built on a foundation of privacy and security, positioning itself as a neutral alternative to mainstream data-mining email providers.

All Proton Mail servers and infrastructure are located in Switzerland, benefiting from the country's strict privacy laws. Because the service is developed, hosted, and maintained primarily within Swiss borders, it is considered a purely Swiss product in terms of digital manufacturing and data sovereignty.

The brand is owned by Proton AG, a company headquartered in Geneva. The ownership remains largely independent, backed by its own revenue and investments from entities that support its privacy-centric mission, rather than being a subsidiary of a larger global tech conglomerate. This independence is a core part of its brand identity and commitment to user confidentiality.
