What Proton Drive is

Proton Drive is end-to-end encrypted cloud storage from the makers of Proton Mail. Files are encrypted on your device, and you can share a file or a folder with another Proton account as view or edit. A command-line client shipped in June 2026.

How they differ

Both keep the party that stores your files from reading them. On Proton an agent signs in as a person and holds that person's whole account. On Rift an agent has its own key and receives only what it was granted.
