From day one, Tresorit has been committed to the highest standards of security and data protection for sensitive information. Our approach combines client-side encryption, zero-knowledge authentication, and cryptographic key management — ensuring a service that is truly end-to-end encrypted.

The backbone of this concept is our award-winning encryption technology which guarantees any data stored and shared in Tresorit is only accessible to you and the intended recipient(s) you have explicitly shared it with. As a result, your files remain protected at all times — no data ever leaves your device unencrypted, so you don’t need to worry about your files in the cloud.
