I think S/FTP is used to describe two global standards; SFTP (FTP over SSH, which is a protocol resembling conventional FTP with a very different internal implementation) and FTPS, which is conventional FTP over SSL/TLS. My professional cryptographer stepson tells me that SFTP is more secure. In my opinion AS2 is preferable to SFTP because of the implementation of MDN's. It is true that 997's provide an acknowledgement function, but you are occasionally going to find that a trading partner claims that they have not received a file when your records show that you sent it successfully over S/FTP. If using AS2 the MDN provides proof of receipt. Having said this, S/FTP tends to be cheaper and easier to implement, which can be significant for small, non-technical trading partners.
