SFTP (SSH File Transfer Protocol)

A secure file transfer protocol that runs over SSH. SFTP is commonly used alongside AS2 for B2B file exchange. Unlike AS2, SFTP does not natively provide non-repudiation, MDN receipts, or standardized message tracking. Some trading partners offer both AS2 and SFTP as transport options.
