We have a client who wishes to send files to us via SFTP (citing that FTP is inherently insecure). We have a Windows Environment (Windows 2003 Server). Currently, I'm reviewing copssh (OpenSSH for Windows, http://www.itefix.no/i2/copssh), and am looking for alternatives, or thoughts on copssh or any other SFTP option for Windows. The simpler to setup and administer, the better. I have never setup an SFTP host, before, so I'm curious what you all would recommend.
