Industry Leading Security Features
Messages are stored on ProtonMail servers using end-to-end encryption at all times and are transmitted in encrypted format between Proton servers and user devices. This largely eliminates the risk of message interception.
Zero Access to User Data
ProtonMail's zero access architecture means that your data is encrypted in a way that makes it inaccessible to us. Data is encrypted on the client side using an encryption key that Proton does not have access to. This means we don't have the technical ability to decrypt your messages.
ProtonMail's open-source software has been thoroughly vetted by security experts from around the world to ensure the highest levels of protection. ProtonMail only uses secure implementations of AES, RSA, along with OpenPGP, while all of the cryptographic libraries used are open source. By using open-source libraries, ProtonMail can guarantee that the encryption algorithms used do not have clandestinely built-in back doors.
