Industry-leading security features
Messages are always stored with end-to-end encryption on Proton Mail servers and are securely transferred between Proton servers and the user's device. This significantly eliminates the risk of messages being intercepted.
Zero access to your email content
Proton Mail's zero-access architecture means that your data is encrypted and technically inaccessible to us. Data is encrypted on the client side using encryption keys that Proton does not have access to. This means we do not have the technical ability to decrypt your messages.
Open source cryptography
Proton Mail's open source software has been rigorously audited by security experts around the world to ensure the highest level of protection. Proton Mail uses only secure implementations of AES, RSA, and OpenPGP, and all cryptographic libraries used are open source. By using open source libraries, Proton Mail can guarantee that there are no surreptitious backdoors built into the encryption algorithms used.
