CSI International 

CSI International (CSI) is an Independent Software Vendor (ISV) providing software and consulting solutions to IT organizations who use IBM’s z/OS and 21CS’s VSEn operating systems and related products.

In 1995, Connectivity Systems, Inc., (now CSI International) was founded to provide a native TCP/IP solution for the enterprises using the z/VSE environment. Appropriately named TCP/IP for VSE, it quickly became the de facto standard for the platform.

In 2002, Connectivity Systems acquired B. I. Moyle Associates, Inc. The acquisition of software and engineering talent enabled Connectivity Systems to expand its reach far beyond networking and VSE. The merged company provides z/OS and VSEn solutions addressing systems management, network performance, data management, production control, automation, and security.

CSI International continues to further develop, market, support, and introduce new industry-leading solutions that enhance, optimize, and extend the mainframe experience while reducing the overall cost of IT. Most recently, CSI International has developed Network Folding® to eliminate network congestion and z/Cobol™, a completely re-imagined compiler that allows existing COBOL code to take full advantage of the hardware innovations present in today’s IBM mainframes.
