About

Tresorit is a zero‑knowledge, end‑to‑end encrypted cloud collaboration platform built for organizations that handle sensitive data. It enables secure file storage, syncing, and sharing while ensuring that only data owners and authorized recipients can access content—Tresorit itself cannot. Files are encrypted on the user’s device before upload and remain protected throughout storage and sharing. The platform supports secure internal collaboration and external data exchange through encrypted file sharing, secure email links, digital signatures, and encrypted data rooms for client and partner collaboration. Tresorit provides granular access controls, auditability, and configurable data residency to help meet strict security and compliance requirements. Designed as a privacy‑first alternative to traditional cloud tools, Tresorit allows teams to collaborate productively without compromising control, confidentiality, or regulatory obligations.
