Kolab Now

  • Email with Advanced Filtering

    Kolab Now delivers threaded email views and server-side Sieve filtering, allowing rules to sort messages before they reach devices. Users manage filters via web interface or scripts, ensuring consistency across clients. Multiple identities and customizable interfaces support professional workflows.

  • Calendar, Contacts, and Task Sync

    Calendars include free/busy scheduling to coordinate without revealing details. Contacts, tasks, and notes sync via ActiveSync for Android, iOS, and BlackBerry, or CalDAV/CardDAV for broader compatibility. Native KDE Kontact clients run on Linux, Windows, and macOS.

  • File Storage and Sharing

    Secure file storage offers granular access controls and sharing options. Recent additions include collaborative editing via Collabora Online for documents and presentations, plus video conferencing rooms for teams.

Tuta

  • End-to-End Encryption for Emails, Subjects, and Attachments

    Tuta encrypts emails automatically between users, covering subjects, bodies, and attachments. External recipients get password-protected links. Contacts and calendars receive the same treatment, ensuring only sender and recipient access data. This zero-knowledge setup means Tuta cannot read user content.

  • Post-Quantum Cryptography

    TutaCrypt protects against future quantum computer threats. The protocol combines Kyber-1024 for key exchange, X25519, and AES-256. New accounts use it now; older ones follow soon. This forward-thinking approach sets Tuta apart in long-term security.

  • Multi-Platform Apps and Integrated Tools

    Native clients run on web, Android (Google Play and F-Droid), iOS, Windows, macOS, and Linux. A unified app handles email, calendar, and contacts. Features include unlimited search via encrypted indexes (premium), 25 MB attachments, HTML signatures, and offline support. Standalone calendar launched in 2024.
