Interconnection

FTP / SFTP

File Transfer Protocol / SSH File Transfer Protocol

Caution Formal standard IETF Since 1971

Judgement: Caution

Unencrypted FTP is unsafe for new work; SFTP-only as a last resort when partners can't speak HTTP APIs.

FTP (RFC 959) is the original file transfer protocol; SFTP runs file transfer over an SSH channel and is the secure variant most enterprises actually deploy.

Unsexy but unavoidable: many regulated industries — banking, insurance, public sector — still hand off bulk data between organisations as nightly (S)FTP drops.
