End-to-end encryption

Proton uses open source, independently audited end-to-end encryption and zero-access encryption to secure your emails. This protects against data breaches and ensures no one (not even Proton) can access your inbox. Only you can read your messages.

Intuitive and free

Our simple, user-friendly design makes it easier to read, organize, and write emails. And our free email means everyone can control what happens to their data.
