SSL (Secure Socket Layer) is a security standard originally developed by Netscape and commonly used to secure HTTP (web) traffic as "HTTPS" and FTP traffic as FTPS. TLS (Transport Layer Security) is a IETF (Internet Engineering Task Force) is standardized and more secure version of SSL.

The following URLs contain very detailed information on these protocols:

Our Serv-U FTP Server and FTP Voyager FTP client both support SSL/TLS. When data in transit is protected using SSL/TLS, confidential information is protected from tampering, snooping, leakage, or accidental exposure.

Both products also support SFTP, a method of securing file transfers via the Secure Shell (SSH) connection protocol. SFTP can be valuable in high-security environments where corporate firewall rules prevent the two-port FTPS protocol from operating properly since SFTP only uses one port for its connection.
