The Fundamental Difference in Trust
Why modern security architects are replacing vendor-managed cloud keys with client-side zero-knowledge seals.
The Tuta Limitation: Email-Only Scope, No Team Chat & Missing Office Suite
Tuta offers robust post-quantum encrypted email and calendar, but lacks the core productivity applications required to operate an active team or business. Tuta has no real-time team channel messaging (no Slack equivalent), no collaborative word processing (no Docs), no spreadsheets (no Sheets), no survey forms, and no video meetings. Tuta teams are forced to license Slack, Zoom, and Google Docs alongside.
