Tresorit is a secure cloud storage and file-sharing platform designed to protect sensitive data with end-to-end encryption. Files are encrypted on the user's device before being uploaded, helping keep stored and shared content private while supporting synchronization across multiple devices.
Key Features
-
End-to-End Encryption – Encrypts files before they are uploaded to the cloud.
-
Secure File Sharing – Share files and folders with permissions, password protection, and link expiration options.
-
File Synchronization – Automatically sync files across supported devices using the same account.
-
Zero-Knowledge Architecture – Tresorit is designed so the service provider cannot access users' encryption keys or stored file contents.
-
Two-Factor Authentication – Adds an additional layer of account protection.
-
Version History – Keeps previous versions of files and allows users to restore earlier copies.
-
Secure Collaboration – Shared folders and granular permissions make it easier to collaborate on confidential files.

Cross-Platform Support – Available for Windows, macOS, Linux, iOS, Android, and the web.
-
Business Administration – Business plans provide centralized controls for managing users, permissions, and activity.
-
Productivity Integrations – Supports integrations with tools such as Microsoft Office and Outlook.
User Interface
Tresorit provides a clean and professional interface centered around encrypted folders called Tresors. Files can be added through drag-and-drop, while sharing and permission controls are available from the file and folder management interface.
The layout is relatively straightforward for users familiar with cloud storage services, although some security and administration settings may require additional configuration.
