Tresorit is a secure all-in-one cloud platform built on end-to-end encryption and zero-knowledge security. It enables individuals, teams, and enterprises to store, sync, and share files and e-signatures, collaborate with colleagues, clients, and partners, and work efficiently with strong privacy guarantees.
Key principles & security foundations
- End-to-end encryption (E2EE)
All files are encrypted on your device before upload and decrypted only locally. Tresorit never has access to your data, keeping your information private by design.
- Zero-knowledge architecture
Encryption keys never leave your device, ensuring that neither Tresorit's servers nor its administrators can decrypt your files. Only you and the people you explicitly authorize can access the contents.
- Compliance
Tresorit complies with international data protection and cybersecurity standards, including GDPR, HIPAA, CCPA, NIS2, DORA, and FINRA. It also holds ISO 27001 certification and offers data residency options—reflecting its commitment to secure, compliant data handling.
Core functions & features
- Syncing
Keep files automatically updated across all your computers. Any change you make locally is synced to the cloud and securely propagated to your other devices and collaborators.
- Sharing
Share content via encrypted links and request files using secure file request links. Apply protections such as passwords, expiry dates, open-count and download limits, email verification, and watermarking.
- Collaboration
Collaborate with internal and external users by sharing folders and subfolders, or using cooperative links. Only users with the appropriate permissions can view or edit content.
- Engage

Tresorit FileSharing is a simple, secure solution for exchanging sensitive documents. Share or request files via encrypted links with controls such as open limits, expiry dates, access logs, and download restrictions.
