Proton Drive
E2EE drive in the Proton ecosystem
Overview
Proton Drive is E2EE file storage where files encrypt before upload and Proton servers cannot decrypt them.
Bundles with Proton Unlimited for mail, calendar, and VPN in one subscription.
Easy setup for Gmail/Drive users. Encrypted documents (Proton Docs, 2024-07) and spreadsheets (Proton Sheets, 2025-12) can be co-edited inside Drive, so it can also stand in for Google Docs / Sheets.

Google Drive / Docs — comparison
