Mailfence

Mailfence is primarily a secure, encrypted email service based in Belgium, but it includes integrated cloud storage (Documents), calendar, and contacts. Storage files can be associated with encrypted emails and are protected by strong encryption. It supports OpenPGP for email and digital signatures. The suite is designed as a private alternative to Google Workspace.

The storage component is less feature-rich than dedicated services but benefits from deep integration within a zero-knowledge communication suite. It ranks as a decent option for users seeking a unified, privacy-focused productivity suite from a strong legal jurisdiction.
