Our Commitment During COVID-19

Dear Valued Clients and Vendors:

My thoughts are with you as we endure the hardships that the next few weeks will bring. Rest assured that CSI has taken swift action to ensure that you receive from us the responsible service on which your organization depends. Many of you are restricted in your movements and usual business practices due to the COVID-19 pandemic. Our company now faces similar restrictions. In order to serve our clients and vendors and to protect the health of our employees and our communities, we have implemented the following protocols for each area of our business.

Technical support and development staff have worked from home for several years now. You should not see any disruption in these services. All employees in these departments have remote access to any tools and resources that they might need to address client issues.

Data center support is restricted to only necessary employees. These employees have a coordinated schedule that prevents more than one person at a time in the data center. While this schedule may—in unusual circumstances—cause a slight delay for access to our hardware, this delay should be minimal, if indeed it occurs.

The sales team has been working remotely for many years also. Work flows that involve sales will continue as in the past. On-site sales calls have been suspended for the next month. Any planned visits after that are contingent on review of the current community standards both for the sales executive and the client.

The administrative staff transitioned last week to remote work. Almost all of these important tasks can be accomplished in such a manner. For the rare times that an administrative employee needs access to the office, the director of administration has devised a schedule for physical visits to our offices. Each administrative employee has a time period whereby they can enter their office privately—with no other employee on site. This allows our administrative staff access to documents and other items that are not accessible from home.

According to the U. S. Department of Homeland Security–Cybersecurity and Infrastructure Security Agency, CSI is an essential critical infrastructure employer. This allows our administrative and our data center employees to travel to work sites unimpeded.

I know that your companies’ missions are vital to your communities and your countries. Rest assured that CSI is here to support those missions as we have always done in the past.

Godspeed through these turbulent times,

Barry Boyer

President

Mainframe Modernization Takes Center Stage: CSI International Heads to GSE 2026

September 14, 2026

The mainframe has never stood still. With each new generation of IBM® mainframe technology comes greater processing power, new capabilities, and new opportunities for organizations running some of the world’s most critical workloads. But realizing the full value of that investment requires more than new hardware. The software running on it must evolve as well. That conversation will be at the center of CSI International’s participation in the 20th International GSE Conference for VSE, Linux, Virtualization, AI and Hybrid Cloud on IBM Z & IBM LinuxONE , taking place September 28–30, 2026, in Leipzig, Germany. As a Strategic Partner of GSE , CSI International is looking forward to once again joining customers, partners, and members of the international mainframe community to exchange ideas and explore what comes next for the platform. This year, CSI will present two sessions focused on a question that has long shaped our development philosophy: How can organizations get more from the mainframe investments they already depend on? Modernization Means More Than Replacing What Works Mainframe modernization does not necessarily mean abandoning established technologies. In many cases, the greater opportunity is to modernize the tools surrounding those technologies so organizations can take advantage of new hardware, new capabilities, and new ways of working without sacrificing the reliability that made the mainframe indispensable in the first place. That philosophy is reflected across CSI International’s ongoing development efforts. At GSE 2026, Barry Boyer of CSI International will provide an update on several of those initiatives during: Mainframe Modernization with CSI International: z/ What You Can Do Monday, September 28, 2026 | 12:00–12:30 The session will explore CSI’s latest development work and continued investment in modernization across the mainframe environment. Among the technologies featured will be z/Cobol® , CSI International’s new COBOL compiler, specifically designed to embrace the power of IBM’s current mainframe. The session will also examine enhancements to CSI’s TCP/IP solutions, including stronger support for security and TLS and more dynamic responses to Internet-based attacks, as well as DataMiner-Dash™ , CSI’s approach to helping organizations examine data and produce reports without the complexity and cost associated with many traditional reporting solutions. Together, these developments represent a common objective: helping organizations extend the value of their mainframe environment while addressing the demands of modern computing. Giving COBOL Modern Muscle On Tuesday, CSI will turn the spotlight specifically to COBOL. For decades, COBOL has remained central to mission-critical computing. The continued importance of the language, however, does not mean that the tools used to compile and extend it should remain frozen in time. That distinction is at the heart of CSI International’s second GSE presentation: Modernizing the Mainframe with the Modern Muscle of z/Cobol® Tuesday, September 29, 2026 | 11:45–12:30 Presenter: David McGuire, CSI International z/Cobol® is a new COBOL compiler specifically designed to embrace the power of IBM’s current mainframe. The goal is not simply to compile existing COBOL differently. It is to give organizations a path for bringing COBOL applications into today's computing environment while continuing to benefit from the stability and reliability that have made COBOL such an enduring part of enterprise computing. During the session, David McGuire will explore both the performance potential of z/Cobol® and the modern capabilities that can be brought into COBOL applications. The presentation will examine opportunities to connect COBOL with technologies and functions that increasingly matter to today's enterprises, including JSON-based communication, AI, modern customer interactions, emerging IBM mainframe capabilities, and other technologies that allow established applications to participate in a rapidly changing digital environment. The underlying premise is straightforward: modernization does not have to mean leaving COBOL behind. It can mean giving COBOL better tools. Getting More From the Modern Mainframe IBM has continued to advance the mainframe platform, creating increasingly powerful infrastructure for organizations whose workloads demand exceptional performance, security, availability, and scale. For organizations investing in that infrastructure, the next question becomes how effectively their software can use it. That is where CSI sees an important opportunity. Modernization can occur at multiple layers of the mainframe environment: improving how applications are compiled, strengthening network security, making data easier to access and analyze, integrating established systems with modern technologies, and developing software that better takes advantage of contemporary hardware. These improvements do not require organizations to disregard decades of investment or replace reliable systems simply because they are established. Instead, they offer another path: build forward from what already works. Join CSI International in Leipzig The International GSE Conference has long provided an important forum for users, vendors, developers, and technology leaders to share knowledge about the evolving mainframe ecosystem. CSI International is proud to be a Strategic Partner of GSE and to continue supporting the community and the conversations that move the platform forward. If you are attending the 20th International GSE Conference in Leipzig, we invite you to join Barry Boyer and David McGuire for their sessions, connect with the CSI team, and talk with us about where your own modernization efforts are headed. 20th International GSE Conference September 28–30, 2026 The Westin Leipzig Leipzig, Germany CSI International Presentations Monday, September 28 | 12:00–12:30 Mainframe Modernization with CSI International: z/ What You Can Do Presenter: Barry Boyer Tuesday, September 29 | 11:45–12:30 Modernizing the Mainframe with the Modern Muscle of z/Cobol® Presenter: David McGuire We look forward to seeing you in Leipzig.
