Tresorit is a cloud storage client that works similar to DropBox, Google Drive and similar service. For those who are concerned about their privacy, Tresorit offers two significant advantages: First, all your files are encrypted with AES-256 *before* they are uploaded to the cloud, which means that they cannot be decrypted by anyone other than you. Secondly, Tresorit and its servers are based in Europe, which puts your files out of reach of a certain U.S government agency that's been making headlines lately.If you are familiar with cloud storage services, you'll find Tresorit very easy to use - simply create a new Tresor storage folder (or choose an existing folder) and the program will encrypt the content and synchronize it with the cloud. You can then access your content from a another computer or mobile devices with the free iOS and Android client apps. Tresorit also allows you to share your cloud folders with other users via email invitation and set folder level access privileges for each.The free version is limited to 5GB of storage and 10 tresors. Paid plans are available that offer 100+ GB of storage, starting at $12.99 a month.
