Proton Drive review

Proton Drive brings the encryption approach of Proton Mail to business file storage. Drive Professional costs $7.99 per user per month billed yearly and includes 1 TB per user, end-to-end encryption that covers metadata, sharing by link or email with access control, and 365 days of version history. Admins get a business admin panel, can delegate admin permissions, enforce two-factor authentication, sign in as a user and protect data with an organization key. Proton Docs and Sheets let teams edit documents in real time without giving up encryption, and a command line tool handles scripted backups. Workspace Standard at $12.99 adds encrypted mail, calendars, video meetings, a VPN and a password manager with shared vaults. The limits are reach and integrations: there are fewer connectors to other business apps than in Box or Dropbox, and the strongest collaboration features depend on moving more of your work into Proton.

Who it is for

Privacy-minded teams that want encrypted storage and the option to add encrypted mail later.
