The Tectia client/server solution is an ideal lightweight solution for secure file transfer, secure remote logins for system administration purposes, and secure use of e-mail and other business applications. The Tectia client/server solution is available for most Unix and Linux platforms (including Linux on IBM System z), for Microsoft Windows, and for IBM mainframes.

The Tectia client/server solution works with any type of Internet (TCP/IP) connection - ADSL, ISDN, modem, Ethernet, WLAN, PPPoE - thus making it widely applicable, totally independent of the network topology, and independent of network address translations.

There are some differences in the availability of features between versions of the Tectia products. For information on the features supported on each product version, see Table 6.3.
