Tresorit

Tresorit is a secure cloud storage and sharing service that encrypts data from beginning to end. It is meant to store, sync, and share private data. 

You can put any kind of file into the Tresorit folder, and all computers that are connected to the same account will instantly sync them. Before being sent to the cloud, files are secured. Decryption can only happen if the owner makes it possible. Content that has been encrypted can be shared without having to be encrypted again.

Securely collaborate with your team from any location. 
Collaborate between workplaces or on the road. Zero-knowledge access from any browser, desktop, Android, iOS, BlackBerry, or Windows Phone device. 

Share files with partners and customers while maintaining control. 
Do not repeat Sony and Target's blunders. Keep complete control over files, even after they have been shared. Access can be adjusted or removed at any time. 

Send confidential files simply, then "unsend" them if needed. 
More than 30% of employees have sent an email to the incorrect recipient. Email attachments cannot be "unsent," putting your critical data in danger. With Tresorit, you may revoke access with a single click. 

Rest easy knowing that your team keeps corporate data secure. 
Employee error is the leading source of data breaches, but you don't have to worry about mistakes. Prevent access using mobile devices. Restrict some files to office desktops. Suspend any team member's access with a single click. 

Please keep in mind that the trial version only lasts 14 days. A Tresorit account and the .NET Framework are required.
