The 6.x version uses the new SSH G3 architecture which is the third complete implementation of the Secure Shell protocol. SSH G3 is based on and fully compatible with the standard SSH2. SSH G3 allows faster secure file transfers and application tunneling without causing processing bottlenecks.

In the 6.x version, the SSH Tectia client tools architecture includes the Connection Broker, that handles all encryption and authentication tasks for these Secure Shell client components.

SSH Tectia 6.x client tools use standard XML-based configuration files. The flexible XML configuration file format allows implementing even complex security policies easily.

The default location of all executables and global configuration files in SSH Tectia Server for IBM z/OS version 6.x has been changed to /opt/tectia.
