What Is End-to-End Encryption (E2EE)?
End-to-end encryption ensures data is encrypted on the sender's device and can only be decrypted by the intended recipient. The service provider cannot access the decrypted data, even if their servers are breached. In cloud storage, this means files are encrypted before leaving your device.
Also known as: E2EE, client-side encryption
Why Does End-to-End Encryption (E2EE) Matter?
Most cloud storage providers encrypt data in transit and at rest, but they hold the encryption keys — meaning they could access your files. E2EE providers like Proton Drive and Tresorit cannot access your data at all, offering the highest level of privacy.
