Tresorit

About

Tresorit is a secure file exchange and collaboration platform aimed at businesses and regulated industries. Its core feature is zero-knowledge end-to-end encryption: files are encrypted on the user's device before they leave it, and only the user and intended recipients hold the decryption keys, so Tresorit itself cannot access the data. The platform is positioned around compliance, citing support for GDPR, HIPAA, and NIS2, along with built-in security controls and regional data residency options, including EU-only storage or any of 12 global locations.

For collaboration, Tresorit offers an encrypted cloud workspace for internal teams, secure data rooms for working with clients and partners, large or sensitive file exchange, eSignature workflows, and encrypted email that works from Outlook and Gmail. Administrators can define granular access rights and sharing policies to keep sensitive information under their control. The website also mentions audit logs.

Tresorit is marketed to healthcare, finance, legal and compliance, IT and security, enterprise, and HR teams, and is described as trusted by more than 11,000 organizations.
