Secure FTP, or SFTP (FTP over SSH) refers to using an SSH connection to transfer files across
the internet to make your
FTP secure. SSH stands for Secure SHell, which is a
network protocol that allows you to transfer your files over a secure channel between two networked devices. Secure
FTP IS NOT FTP, but a new protocol designed for secure transmission of data.
CheapFTP.com uses similar SSL encryption techniques through the free web based
FTP client to secure your data while transferring it.
