Proton Launches New End-to-End Encrypted Spreadhseets for Ultra Secure Data Handling

Proton has introduced Proton Sheets, an end‑to‑end encrypted spreadsheet tool that joins its Docs offering in the Proton Workspace suite. The service is free for all Proton Drive users and encrypts both cell data and metadata, leveraging Swiss privacy law for stronger legal safeguards. With 54 % of European businesses still relying on cloud‑based spreadsheets, Proton positions Sheets as a privacy‑first alternative to Google and Microsoft solutions. The launch coincides with broader Workspace upgrades, including AI features and expanded VPN server locations.
