- File Transfer Protocol with SSL security. FTPS is running FTP
over a secure SSL/TLS connection. This is similar to standard FTP
but performs operations over an encrypted link (SSL)
and is thus said to be secure
FTPS is also referred to as "FTP Secure", "FTP/SSL", "FTP SSL/TLS", "FTP/S" or "FTP-SSL".
A client using FTPS connects to the FTP server using port 990 as the command port when running in "implicit mode". In "explicit mode" (also known as FTPES) the client connects to the standard FTP port (port 21) and explicitly requests SSL security.
FTPS is sometimes confused with SFTP, but the two are different.
