Description

Tresorit is a Swiss-based cloud storage and file-sharing service founded in 2011, designed with a strong focus on security and privacy. It offers end-to-end encryption (zero-knowledge) by default, ensuring that only users can access their files, and even Tresorit cannot decrypt user data. The platform is widely used by businesses, legal, and healthcare sectors for secure collaboration and compliance with strict data protection regulations. Tresorit also avoids unnecessary data consumption, focusing on efficient and secure file storage without AI-driven bloat.

In 2025, Tresorit launched Engage Rooms, customisable secure data rooms for external collaboration, and achieved NIS2 compliance, strengthening trust in its proprietary software.
