Vault IndexTresorit · Zero-knowledge encrypted team storage
Tresorit review
Tresorit is a Swiss-based end-to-end encrypted file sync and share service popular with law firms and healthcare bodies that want zero-knowledge storage. It covers secure sharing well but lacks native deal-room features like Q&A or indexing.
What it does well
- +End-to-end, zero-knowledge encryption means Tresorit itself cannot read stored files.
- +Business and Business Standard plans include e-signature, granular link controls and detailed audit trails.
- +The Engage for Business product adds branded, watermarked external portals for client-facing sharing.
Where it falls short
- −Per-user pricing rises quickly for larger teams compared with flat-fee competitors.
- −Advanced compliance and admin features are reserved for higher Business and Enterprise tiers.
Pricing
Business Standard starts at roughly $18 per user per month billed annually with a minimum team size, while Business Plus and Enterprise cost more and add compliance features; a separate Engage product for client-facing rooms is quoted separately.
Security and compliance
Tresorit uses end-to-end and at-rest encryption with a zero-knowledge design, and its infrastructure is ISO 27001 certified.
