Tresorit is a zero‑knowledge, end‑to‑end encrypted cloud collaboration platform designed for individuals and organizations that need uncompromising data security. It enables users to securely store, sync, and share sensitive files while ensuring that only the data owner and explicitly authorized recipients can access the content. Files are encrypted on the user’s device before upload, and encryption keys are never available to Tresorit, eliminating the risk of provider‑side data access or exposure. Built as a privacy‑first alternative to conventional cloud services, Tresorit supports secure internal collaboration as well as controlled external data exchange. Teams can share files and folders with granular permission settings, revoke access at any time, and monitor activity to maintain full visibility and control. External sharing is protected through encrypted links and secure email delivery, replacing risky attachments and uncontrolled file transfers. Tresorit also enables secure, long‑term collaboration with clients and partners through encrypted data rooms that centralize documents, tasks, and approvals in a single protected workspace. Integrated digital signatures allow documents to be reviewed and signed without leaving the encrypted environment, preserving security throughout the entire document lifecycle. With advanced admin controls, auditability, and configurable data residency options, Tresorit is built to support strict regulatory and compliance requirements. By combining strong security with ease of use, Tresorit allows organizations to collaborate productively while maintaining confidentiality, ownership, and trust over their most sensitive data.
