Our verdict
Tresorit is an end to end encrypted cloud storage service built for businesses, with zero knowledge encryption meant to keep company files, client information and contracts under the customer's own control. For teams in industries with strict data rules, its compliance controls and regional data residency options are the main reasons to consider it.

Sharing, data rooms and eSign
Files can be shared with others through encrypted links, and data rooms give clients or prospects a secure digital space where documents can be accessed and managed by approved users. Sensitive contracts and invoices can be signed electronically with eSign. A Drive integration lets people upload and open files from their file manager without keeping copies on the computer. Sync across devices and offline access are included, and version history tracks changes so earlier versions can be restored.
Encryption and compliance
Files are protected with zero knowledge end to end encryption, so recipients alone can read them and the provider cannot access files or keys. Certifications with ISO 27001, TISAX and FINRA sit alongside GDPR and HIPAA alignment, and NIS2 is also referenced. Data residency can be chosen by data center, which helps organisations meet company rules and jurisdiction specific requirements. Inviting colleagues adds them to an encrypted main folder, which keeps shared work inside protected space.
