openFT is an enterprise file transfer product sold by Fujitsu. openFT runs on Windows, several Unix platforms (Linux, Solaris), BS2000/OSD and z/OS. openFT should not be confused with the openFT file sharing protocol. It allows the sending of files inside of WAN environments without the need of sharing secrets or setting up users on both sides of the communication. As long as the sender knows the so-called "transfer admission", it is allowed to send a file to the receiver, who in turn takes the transfer admission to decide where to put the received file.
