Tresorit AG FAQs

Tresorit is the most secure way to store and share files in the cloud. No Tresorit admin, hacker or government can access the data you store. Hacking just one file would take a lifetime.

Tresorit uses “end-to-end encryption” to guarantee the security of the uploaded file. Your files are encrypted before they leave your device and remain fully encrypted until they reach the recipient. Only you have the keys to open or share them.

Secure services are usually a pain to use, but Tresorit's ease of use has been praised by Forbes, PCWorld and thousands of users. Our ratings on all app stores rival those of Dropbox. (more)

Our competitive advantage over standard EFSS services is the highest level of security guaranteed by built-in, by default end-to-end encryption. Unlike Dropbox or Box, Tresorit’s end-to-end encryption protects files by encrypting them on the user’s device before uploading it to the cloud. Our patented technology is based on zero-knowledge principles, which means we don’t store passwords and encryption keys of our users, making it technically impossible to access users’ files even in case of a data breach. Only the users and those who they share with have access to the decryption keys and so the files. No one else, not even our own developers can see them. Tresorit’s patented sharable encryption technology is a unique solution for sharing encrypted files and manage file-level permission levels (DRM) at the same time. (more)
