CSI International (CSI) is an Independent Software Vendor (ISV) providing software and consulting solutions to IT organizations who use IBM’s z/OS and z/VSE 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 z/VSE solutions addressing systems management, data management, production control, automation, and security.
CSI International continues to further develop, market, support, and introduce new industry-leading solutions that enhance and extend the mainframe experience while reducing the overall cost of IT.
The corporate headquarters are located in Williamsport, Ohio, USA.
CSI’s software solutions are available worldwide through its international distribution network, and directly in North America from CSI and select business partners.
For many decades, Emerald Software GmbH has maintained a successful and trusting partnership with CSI International as a distributor and reseller of CSI mainframe software solutions in Central Europe.
