Vendor Profile

Tuta

Tuta (formerly Tutanota) is an open-source, end-to-end encrypted email provider based in Germany. Every email, contact, and calendar entry is encrypted at rest with zero-access architecture. Tuta uses its own encryption protocols rather than PGP, encrypting subject lines in addition to message bodies. While primarily focused on GDPR compliance and personal privacy, Tuta's business plans offer custom domains, team management, and whitelabel options.
