Tresorit is an end-to-end encrypted, secure cloud storage and file sharing solution designed to store, sync and share confidential data.

Simply turn any folder to a Tresor and place a file into it and they will automatically sync with every devices connected to the same account. Encryption is performed before the data gets uploaded to the cloud. Decryption is only possible with permission from the owner and already encrypted contents can be shared without re-encryption, but in a 100 percent secure way.

To prove the security of Tresorit, the company initiated a bounty of $50,000 and invited leading Universities and more...

I recently began using Tresorit, and so far I like it. In addition to Tresorit's security features like client-side encryption and servers based in the EU, things I like about the software include being able to sync any folder I want, so I'm not constrained to having to put everything into a single folder like Dropbox, and being able to not sync some folders (called "Tresors") on some computers, which is similar to Dropbox's selective sync feature.

The only thing I don't like is that Tresorit doesn't handle Mac OS X metadata properly (or at all). Most annoying is that Mavericks tags aren't synced. Almost as annoying is Tresorit doesn't like "invalid characters" like question marks, which may be invalid on some other operating system (Windoze), but are perfectly valid in OS X. Another annoyance is that file extensions that are hidden on the source Mac appear visible when synced to another Mac. Similarly, files that are invisible on the source computer show up as visible when synced to another computer.

I forgot to note that files with "invalid characters" like question marks are not synced, so be careful when using these "special" characters.


I heard back from the dev, who says that "we are working on enhancing our Mac app and in the close future it will recognize and sync all the tags and metadata" and "we are working on a solution for these characters, currently we do not sync those files that contain these special characters."

Tresorit is good stuff. Have been using it for a while now, using duplicate folders rather than originals at the moment. Seems solid, takes a while to sync single files but really quite reasonable for 100+ files in a folder. I like the idea of client side encryption, rather than server side. Would be nice to have a version indicator in the preferences, an updating indicator as well. Also would be nice to know what systems are accessing the tresors, i.e., my iPad/iPhone/laptop and some indication about how synced they are. This software is good and seems solid. Have had no crashes yet although it is easy to confuse it when one folder is removed/trashed on one machine, and its tresor is removed on the other using tresorit, it throws a lost error. Have also read the white paper. DropBox is still used for convenience but knowing that its not really secure, I only use it for public stuff. Prefer Tresorit for privacy. 5 stars.

I bumped into Tresorit about a month ago and have been using Tresorit for Mac from the very early stages. What I really like is that it is easy to use, the UI is very intuitive and it syncs smoothly and quickly for me. I gave lower score on the features, because I deadly miss referrals and upgrade options, but they told me it is coming in a few weeks, so I may improve it :) On the other hand the security and the privacy Tresorit offers is incomparably better than the others out there (and it it very important for me since I store there many of my business stuff). Definitely worth a try, if you have not yet done that, it is time to move on from dropbox!
