End-to-end encryption

The core of TeamDrive Professional is data encryption. In order to meet the high data protection requirements, TeamDrive relies on highly secure end-to-end encryption (English abbreviation: E2EE).

Complete end-to-end encryption means: The data is encrypted on your PC or smartphone before it is transported over the Internet, and then transmitted encrypted to the server (usually TeamDrive Cloud or your own cloud server) and then stored encrypted in the cloud.

Only at the destination, i.e. on the computer of the addressee of the files, is the data decrypted again.

File transfer takes place on the one hand as part of the automatic data synchronization with members of your TeamDrive Spaces instead.

You can also send files directly to people – including external recipients who do not work with TeamDrive or are not a member of your TeamDrive space.

You can just as easily receive files from external senders – and of course these are always end-to-end encrypted.

Always and in every case all file transfers are end-to-end encrypted!
This function is deeply anchored in our cloud solution and cannot be switched off, which ensures complete data security.

You don’t have to worry about encryption or decryption – it all happens automatically in the background.
The only important thing for you to know is that the keys required for encryption and decryption are only and always located on the users’ computers – never on TeamDrive!
Even we, as providers of the cloud solution, have no access to or insight into your data.

In order to offer as little attack surface as possible for malicious attacks and data theft, strict attention was paid to seamless and highly secure encryption, authentication and the isolation of security-relevant areas when planning and developing our cloud solution. The underlying design concept is called Security by Design .

Reading tip: Security by Design

This also means that the security of our product is continuously tested and certified by highly competent and independent official bodies.

Special information for experts

TeamDrive uses AES-256 encryption for end-to-end encryption. To do this, TeamDrive uses asymmetric encryption with a public key procedure. When data or messages are exchanged, a key pair is generated for each user. This pair consists of a secret key (private key) and a public key (public key).

The sender's computer encrypts the message or file with the public Public Key. The recipient's computer decrypts the receiving file with the private key.

The end-to-end encryption protocols contain a digital certificate that authenticates both end points of the communication. To ensure that data is safe from unauthorized access, only authorized people receive the keys, not the cloud provider or network operator.

With end-to-end encryption for a published file, the key used for this file is integrated into the link (URL). The recipient receives this link directly via email, for example - and not via the TeamDrive Cloud. For this reason, confidentiality between sender and recipient is maintained.
