Tresorit is an online cloud storage that uses patented end-to-end encryption technology to guarantee the safety of all the data you share and store.

Tresorit enables seamlessly work across offices, and on the road without giving up on security. Upload and access your files with zero-knowledge encryption from any desktop and mobile device using Windows, macOS, Linux, Android, iOS, and from any browser. 

End-to-end encryption

Public key cryptography
resorit encrypts every file on your devices before they are uploaded to the cloud applying the Advanced Encryption Standard algorithm using 256-bit keys. Your files never get decrypted on Tresorit's servers.

Zero-knowledge privacy means that no one, not even Tresorit, can look into the content of your files. Only you and those who you decide to share with can access them.

Client-side integrity protection
Applying a Message Authentication Code to each file, Tresorit guarantees that the contents of your files cannot be modified without your knowledge, even if somebody hacks our system.
