Unrivaled Security Features
Your messages are stored on Proton Mail servers with end-to-end encryption, ensuring secure transmission between Proton servers and user devices. This significantly reduces the risk of message interception.

Zero Access to Your Email Content
Proton Mail employs a zero access architecture that encrypts your data in a manner inaccessible to us. The encryption occurs on the client-side using keys that Proton cannot access, meaning we lack the technical means to decrypt your messages.

Open-Source Cryptography
Proton Mail's open-source software has undergone extensive review by global security specialists to ensure maximum protection. We utilize secure implementations of AES, RSA, and OpenPGP, with all cryptographic libraries being open-source. This transparency allows us to confirm that our encryption algorithms are free from covert backdoors.
