In order to use SFTP, you'll need both a Client program and a Server/Daemon software. See also: our list of the Best Free SFTP Servers One of the most overlooked advantages of using SFTP and its underlying protocol is the ability to deliver files with all of their attributes if needed, including permissions, Time/Date, Size and other information that isn't available when using FTP. The resulting benefits of this method is a Single, Efficient and Secure connection transferring data through the firewall, resulting in a faster transfer speed. With SFTP, files are transferred in-line over the Main Control Connection, rather than having to open a new, separate connection for transfers like FTP. Unlike FTP/S, you cannot turn off encryption with SFTP, which is nice when you are trying to ensure that all connections are Secured and Encrypted for anyone transferring files. Unlike File Transfer Protocol (FTP), STFP communicates over a Secure connection initiated through SSH2 and is a Packet-Based protocol, instead of a Text-Based protocol like FTP, which in turn will faster due to less data being transferred over the wire than FTP text-based protocol. SFTP was developed in the 1990's and is detailed thoroughly in this RFC Draft Specification.

SFTP, which stands for SSH (or Secure) File Transfer Protocol, usually runs on Port 22 (but can be assigned whatever port you want) and is a way for transferring files between machines over a Secure and Encrypted Connection, unlike FTP, which transfers data over an insecure and unencrypted connection.
