What IBM z/OS Communications Server can do for your business

IBM® z/OS® Communications Server, a high availability enterprise transaction and data server, provides common applications, such as FTP, Telnet and the remote execution of applications. Built for optimum productivity, it provides a secure platform for developing and sharing mainframe workloads.

IBM z/OS Encryption Readiness Technology (zERT) Network Analyzer, a new z/OSMF plugin, is now available for you to easily query and analyze the cryptographic protection attributes of your z/OS TCP/IP and Enterprise Extender connections.
