Tresorit

What Is Tresorit and How Does It Work?

Tresorit is an end-to-end encrypted cloud storage platform for businesses. Legal firms, financial services, healthcare organizations, and privacy-focused enterprises use Tresorit's SecureCloud for business file storage, Engage for branded client data rooms, and Basic tier for personal use, all with zero-knowledge encryption ensuring only the user can decrypt their data.

The typical Tresorit deployment covers zero-knowledge encrypted cloud storage, e2e encrypted file sharing, branded client data rooms via Engage, and cross-platform desktop and mobile apps.

Tresorit competes against Sync.com, ProtonDrive, and other privacy-focused encrypted cloud storage platforms.

Tresorit Deep Dive: Zero-Knowledge Encryption Deep Dive

End-to-end + zero-knowledge encryption

Tresorit encrypts data on the user device before upload. Only the user (with their key) can decrypt. Tresorit servers cannot access user data. This is stronger than server-side encryption that most cloud storage platforms use.

SecureCloud + Engage + Basic tiers

SecureCloud for Business is the primary business file storage. Engage for Business is branded client data rooms for external collaboration. Basic is personal use tier.

European infrastructure + GDPR

Data stored on European servers with GDPR compliance native to the platform. Swiss privacy laws apply to Tresorit AG.

Compliance depth

GDPR, HIPAA-aligned handling, ISO 27001, SOC 2. Legal firms, financial services, and healthcare buyers valuing compliance depth get the strongest fit.
