Abstract: A technology is described for transferring a file from an unsecure network to a secure network. An example method may include identifying an unsecure account profile and determining that a file is to be transmitted from an unsecure network to a secure network using a one-way transfer device. In response, the file may be obtained from a file storage location and an unsecure account profile name for the unsecure account profile may be identified. A request may be made that the one-way transfer device to transmit the file and the unsecure account profile name to the secure network. The file and the unsecure account profile name may then be transmitted to the secure network, where a secure account profile corresponding to the unsecure account profile may be identified in the secure network and the file may be placed in a folder associated with the secure account profile.
