Proton Drive

End-to-end encryption

Files are encrypted before they are uploaded. Proton states that only the owner and the people they share with can open them, and that Proton itself cannot.

Sharing controls

Files, photos, documents and spreadsheets are shared by link, with password protection, expiry dates and the ability to revoke access at any time.

Proton Docs and Sheets

Encrypted document and spreadsheet editors with real-time collaboration are built into Drive, and the editor is included on the free plan.

Photo backup

The mobile apps back up photos automatically and support collaborative albums for sharing them.

Desktop sync

Desktop apps for Windows and macOS sync files between the computer and the cloud. A command-line client is offered for Linux, macOS and Windows.

Long version history

Paid plans from Drive Plus allow previous versions of a file to be recovered for up to 10 years.

Tresorit

Zero-knowledge encryption

Files are end-to-end encrypted on every plan, including the free one. Tresorit states that it cannot access customers' files or keys.

Encrypted link sharing

Files are shared through encrypted links with link security settings that vary by plan. Personal Pro and the business plans add file requests.

Sync and Tresorit Drive

Files sync across devices with offline access, and Tresorit Drive adds them to the local file manager without storing them on the computer.

Version history and recovery

Earlier versions are kept for each file, 5 on Personal Lite, 10 on Personal Essential and 25 on Personal Pro, and deleted files can be restored.

Business controls

Business adds data residency options, single sign-on and custom admin policies. Business Pro adds an auto-deletion policy, custom domain and Active Directory support.
