# Tresorit review

Zero-knowledge encrypted cloud storage and file sharing for businesses, built for compliance-driven teams in finance, legal, and healthcare.

By Noah — last updated & pricing verified September 15, 2026.

> **Tresorit** is a zero-knowledge, end-to-end encrypted cloud storage service: every file is encrypted on the user's device before upload, so Tresorit's servers never hold a readable copy or the keys to decrypt one.

Beyond basic file sync, Tresorit's business tiers add SecureCloud for team storage and sharing, Tresorit Engage for encrypted "data rooms" used in due diligence, legal review, and client collaboration with people outside the organization, and an eSign add-on for encrypted digital signatures. Business plans layer in admin controls: SSO (Azure AD, Okta, Google), data residency choices (EU-only storage or one of 12 global regions), granular sharing permissions, and audit logs. The product targets regulated industries — financial services, legal, and healthcare — where the incumbent alternative is often a compliance-blessed but less convenient tool, or a general-purpose cloud drive that lacks zero-knowledge encryption entirely.

## Facts

- Website: https://tresorit.com
- Pricing: Custom pricing
- License: Paid
- Platforms: web, windows, macos, linux, ios, android
- Best for: financial, legal, and healthcare teams that need zero-knowledge encrypted file storage plus encrypted data rooms for sharing with outside parties
- Standout feature: Zero-knowledge, client-side encryption combined with Tresorit Engage's encrypted data rooms, letting compliance-sensitive teams collaborate with external clients and partners without ever exposing files to Tresorit's own servers.
- Biggest weakness: No permanent free tier and no self-serve pricing transparency: exact per-user costs are not published as plain numbers on the live pricing page (they render via client-side JavaScript), and third-party sources quote inconsistent figures, so buyers have to request a quote or dig through a trial signup to confirm current cost.
- Third-party ratings: Capterra 4.8/5 (130 reviews)
