How secure is NSU Dropbox?

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 want to be used when downloading the drop-off. The passphrase is not stored on NSU Dropbox, and cannot be recovered if lost. No one can access the files without it.

All files uploaded are temporarily stored on NSU Dropbox.

All data is subject to the Data Protection regulations and laws of NSU and the United States of America.

NSU Dropbox is in no way a "cloud" service. Everything is stored (even temporarily) on equipment directly owned by NSU, and managed by its own IT staff.

All access to data is very strictly controlled by NSU. All access to data on NSU Dropbox is logged and monitored.

Furthermore, uploaded data is only held on NSU Dropbox for a maximum of 20 days, after which time it is automatically deleted. There is no "undelete" function available. No backups are taken of the uploaded data (it's only a transitory stopping point), so no uploaded data ever moves off NSU Dropbox 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.
