Secure File Transfer Protocol ( SFTP )

Secure File Transfer Protocol (SFTP) is a network protocol for securely accessing, transferring and managing large files and sensitive data.
Designed by the Internet Engineering Task Force as an extension of Secure Shell (SSH), SFTP enables access, transfer and management of files over a network. It's used for secure file transfers over Transport Layer Security and the transfer of data for virtual private network (VPN) applications.
