Industry-leading security features:

Messages are stored on Proton Mail servers with constant end-to-end encryption and securely transmitted between our servers and your devices, significantly minimizing the risk of message interception.

Zero access to your email content:

Proton Mail adopts a zero access architecture, meaning your data is encrypted in a manner that even we can't access. Your information remains encrypted using a key that only you possess. This ensures we lack the technical ability to decrypt your messages.

Open-source cryptography:

Proton Mail employs open-source software thoroughly reviewed by worldwide security experts, guaranteeing the highest levels of protection. We exclusively use secure implementations of AES, RSA, and OpenPGP, along with open-source cryptographic libraries. This eliminates the possibility of clandestine backdoors in the encryption algorithms.
