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 z/VSE solutions addressing Systems Management, Data Management, Production Control, Automation and Security.   Connectivity Systems Inc. and B. I. Moyle Associates, Inc. are now fully integrated as CSI International.   CSI International continues to further develop, market, support and introduce new industry-leading solutions designed to enhance and extend the mainframe experience while reducing the overall cost of IT.   The mission of CSI International is to “Help Customers Succeed.” Putting our customers first is the driving force behind everything we do.
