Atom Transfer offers end-to-end data encryption.
Files sent with Atom Transfer are encrypted on the sender's browser (with the AES algorithm) before being sent to the server. The server therefore does not have the capacity to access the stored data.
A TLS session ensures the integrity of the connection: that is to say, that your computer connects to the Atom Transfer server and not to a third-party server. Symmetrically, the data is decrypted by the users' browser.
If a third party intercepts the message containing the transfer link, they could access the data. Adding a password shared through a second channel helps limit the risk of unauthorized access to data.
It also protects the link if the recipient's authentication has been compromised.
The Atom Transfer solution is based on the use of a secret key specific to each user. This key is used in particular to encrypt the links contained in the transfer history. It is stored in your browser and not on the server. As a result, even the solution hosting provider will not be able to access the data.
It is therefore up to the user to keep this key which will be requested when they connect from another computer.
Copy/paste your personal key into a document, drive or any other secure location you remember. If your password manager prompts you, save the key, it's a good practice!
Atom Transfer intends to distribute its servers across several hosting providers in order to limit the risk of downtime. To provide a high quality of service, data will be stored as close as possible to users, in regional data centres.Atom Transfer's application layers are deployed on infrastructures operated by ISO/IEC 27001-certified hosting providers.
