Tresorit is an online cloud storage service based in Switzerland and Hungary that emphasizes enhanced security and data encryption for Businesses and individuals/freelancers.
Tresorit was founded in 2011 by Hungarian programmers Istvan Lam (CEO), Szilveszter Szebeni (CIO) and Gyorgy Szilagyi (CPO). Tresorit officially launched its client-side encrypted cloud storage service after emerging from its stealth beta in April 2014.
By the end of 2016, Tresorit launched a beta of the software development kit (SDK) ZeroKit. In January 2017, Apple’s SDK project CareKit announced the option for mobile app developers using CareKit to integrate ZeroKit, enabling zero knowledge user authentication and encryption for medical and health apps.
The Business version offers up to 1TB of storage space per user (the Solo version offers 2TB for one user) and extra security features such as DRM, granular access levels and other functions which aim to create a safer collaborative environment. Tresorit has been likened to a high-security alternative to Dropbox.
Tresorit’s service is accessible through client desktop software, web-based application and mobile apps. Currently, the software is available for Windows, macOS, Android, Windows Phone 8, iOS, and Linux.
