Tresorit is an online cloud storage service based in Switzerland and Hungary that emphasizes enhanced security and data encryption. The service offers users 5 GB of data for free, though it has offered 50 GB to users through promotions with Lifehacker and GigaOM for a limited period of time. It has been likened to a high-security alternative to Dropbox.
As an added measure for security, Tresorit's service is only accessible through client desktop software. A web-based file uploader does not exist. Currently, the software is available for Windows, Mac, Android, Windows Phone 8, iOS and BlackBerry OS. Linux version is planned.
Tresorit officially launched its end-to-end encrypted cloud storage service after emerging from its stealth beta in April 2014.
"Tresors" (German for vault) are encrypted counterparts of uploaded directories. Tresors automatically sync with the cloud as files are added or removed from them, similar to Box.com and Dropbox's desktop software. The main difference between Tresorit and its competition that Tresorit applies AES-256 client-side encryption to files while they’re still local and then uploads them to the cloud. Then there are additional layers of security, but the key info is that the encryption key never leaves the user.
Since April 10, 2013, Tresorit has hosted a hacking contest, offering $10,000 to anyone who can hack their data encryption methods to gain access to their servers. Tresorit maintains that the contest is hosted on a completely independent server separate from their users' files. In 2013 the company increased the reward to $25,000, challenging top hackers from institutions like Harvard, Stanford or MIT. The current reward is $50,000.
Users of Tresorit start with 5 GB of storage for free.
For bought storage: prices range from 5.99 EUR/month for 20 GB to 99.99 EUR/month for 1000 GB.
