Tresorit is a cloud storage and file collaboration platform that uses end-to-end encryption to protect sensitive data. The company's architecture employs zero-knowledge encryption, where decryption keys are stored on individual user devices rather than on servers, ensuring that no one can access data without authorization, including Tresorit itself. This differs from server-side encryption used by many cloud storage providers, where files are only encrypted after reaching their destination. The platform serves businesses that handle sensitive information, including accounting firms, financial services companies, and organizations requiring compliance with regulations such as GDPR, HIPAA, SOC 1, SOC 2, HITRUST, and FedRAMP. Tresorit is ISO/IEC 27001-certified and designed for distributed workforces and global operations. The platform provides cloud-based file storage and sharing with a folder structure that mirrors mainstream operating systems. Features include centralized administration, downloadable activity logs for tracking file access, secure file sharing and request links, and encrypted data rooms for client collaboration. Administrators can monitor all users and control access regardless of location. Tresorit offers publicly available whitepapers that detail how the platform and encryption system operate, along with a knowledge center containing educational resources about cybersecurity principles. The company targets organizations with IT-savvy clients who require transparent, industry-standard cybersecurity protocols for handling confidential data throughout its lifecycle.
