What is Proton?

Editorial review
Proton offers a suite of privacy-by-default services designed to protect users' digital lives. Founded by scientists at CERN, Proton's mission is to provide an internet that prioritizes freedom and privacy, ensuring that user data belongs to them, not to tech companies or governments. All services are built with end-to-end encryption and zero-access encryption, meaning even Proton cannot access user data without permission. The product suite includes encrypted email (Proton Mail), secure VPN (Proton VPN), end-to-end encrypted cloud storage (Proton Drive), collaborative document and spreadsheet editing (Proton Docs and Sheets), a password manager (Proton Pass), a 2FA authenticator (Proton Authenticator), and secure video conferencing (Proton Meet). Proton also offers an AI assistant, Lumo, designed for confidential conversations. The services are open-source, independently audited, and protected by strong Swiss privacy laws, making them suitable for individuals and businesses seeking robust digital privacy and security across all devices.

Available on: Web, iOS, Android, Windows, macOS, Linux
