When Tectia ConnectSecure on Windows workstations is used together with Tectia Server for IBM z/OS on mainframe, TN3270 application connections can be tunneled transparently.

The administrator specifies tunneling rules for the TN3270 application connection(s) that need to be secured. Alternatively, it is possible to require that all terminal connections initiated by a certain terminal emulator will be tunneled.

When the terminal client accesses a remote mainframe, Tectia ConnectSecure captures the connection transparently and establishes a secure tunnel between the workstation and IBM z/OS system. All TN3270 application connection traffic is then transmitted over an encrypted Secure Shell tunnel, ensuring confidentiality of passwords and application data.
