Google encrypts files in transit and on its disks with AES-256, using keys managed by its own key management service, so its systems can decrypt them. File names, descriptions, owners and activity logs are encrypted on disk the same way. Client-side encryption, which Google cannot decrypt, exists only in some paid Workspace editions for organizations and has to be switched on by an admin; personal Google accounts cannot use it. Decryption happens on Google's servers, so the web, desktop and mobile apps work the same way.

File contents, file and folder names and thumbnail previews are encrypted on your device with keys generated there (OpenPGP, Curve25519). Proton can see creation and modification times, permissions, the username that uploaded each file and the size of the encrypted file. The web app receives its encryption code from Proton's servers every time it loads.

Penetration tests of the web app (September to October 2021), the Android app with its API (July to August 2022) and the iOS app (August to September 2022); no Drive audit report for the Windows or macOS apps is published
