SSH Tectia deployments can be roughly grouped into secure system administration, secure file transfer, and secure application connectivity use. The application areas overlap to some extent.

Secure system administration concerns the replacement of the unsecured Telnet, Rlogin and FTP protocols. Secure file transfer concerns securing interactive and automated file transfer in server-to-server environment. Secure application connectivity refers to secure connections to business applications using either secure terminal or secure tunneling of TCP traffic.
