Tresorit

Founded in 2011 by Istvan Lam, Szilveszter Szebeni, and Gyorgy Szilagyi, Tresorit provides a secure alternative to traditional cloud storage services by emphasizing privacy and data protection. The platform utilizes client-side end-to-end encryption, ensuring that files are encrypted before they leave the user's device and can only be decrypted by the intended recipient. This zero-knowledge architecture means that even Tresorit cannot access user data. Key features include secure file storage, synchronization across devices, granular access controls, and secure file sharing with password protection and download limits. Tresorit serves a diverse clientele, including businesses and individuals who prioritize data security.
