Proton is a privacy-focused technology company founded in 2014 and based in Geneva, Switzerland. It develops a suite of tools built around encryption, open-source software, and security auditing, with the stated mission of building a better internet where privacy is the default. The company has never taken venture capital funding and is structured as a for-profit entity with the non-profit Proton Foundation as its primary shareholder, which ensures the company prioritizes people over profits.
Proton's flagship product, Proton Mail, is the world's largest end-to-end encrypted email service, serving over 100 million users and organizations worldwide. The company has since expanded its privacy-first suite to include a virtual private network (Proton VPN), cloud storage (Proton Drive), a calendar (Proton Calendar), a password manager (Proton Pass), and more recent additions such as document editing (Proton Docs), spreadsheets (Proton Sheets), video conferencing (Proton Meet), and a wallet service (Proton Wallet). All services are open-source and independently audited for security.
The company operates across privacy technology, consumer software, enterprise software, and security verticals. Its tools have earned recommendations from the United Nations and endorsements from millions of users globally.
