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

Drive’s search and AI may still be stronger, but Proton structurally prevents Google from parsing content or feeding AI. Proton Docs (2024-07) and Proton Sheets (2025-12) add encrypted real-time co-editing.

Pros

  • ✓ Simple setup familiar to Google users
  • ✓ Password-protected E2EE share links
  • ✓ Swiss privacy law protection

  • − Not a full equivalent of Google Docs / Sheets
  • − Large file sync can be slower than Google Drive

Best for

  • Individuals replacing Google alongside Proton Mail
  • Encrypted backup of contracts and sensitive PDFs
  • Users wanting Swiss/EU E2EE cloud storage

Not ideal for

  • Teams that require full Google Docs / Sheets compatibility
  • Large free media libraries
