How secure is DI - Die Ingenieure Datenaustauschportal?

All files are transferred across the network securely encrypted.

If you are sending personal or confidential data, tick "Encrypt every file" when creating a new drop-off. Then the passphrase you enter must be used when downloading the drop-off. The passphrase is not stored on DI - Die Ingenieure Datenaustauschportal, and cannot be recovered if lost. No one can access the files without it.

All files uploaded and temporarily stored on DI - Die Ingenieure Datenaustauschportal are held on equipment owned and operated at DI - Die Ingenieure's own Data Centre.

All data is subject to the Data Protection regulations and laws of DI - Die Ingenieure and the country.

DI - Die Ingenieure Datenaustauschportal is in no way a "cloud" service. Everything is stored (even temporarily) on equipment directly owned by DI - Die Ingenieure, and managed by its own IT staff.

All access to data is very tightly and strictly controlled by DI - Die Ingenieure. All accesses to data on DI - Die Ingenieure Datenaustauschportal are logged and can be easily checked if you are ever concerned that a 3rd party might have gained access to your data.

Furthermore, uploaded data is only held on DI - Die Ingenieure Datenaustauschportal for a maximum of 21 days, after which time it is automatically deleted. There is no "undelete" facility available at all. No backups are taken of the uploaded data (it's only a transitory stopping point), so no uploaded data ever moves off DI - Die Ingenieure Datenaustauschportal itself onto other equipment or media such as backup tapes. After an uploaded file has been deleted, there is no way of recovering the file.

Retrieval of a drop-off by a recipient can only be done with both the drop-off's Claim ID and Passcode.
When dropping off files, you can choose not to send either or both of these to the recipient automatically: you would then need to send that information by hand yourself.
