Boosting Enterprise ROI with Scalable Connectivity

Connect/MP is a powerful, enterprise-grade solution that combines industry-leading ZIP compression, seamless cross-platform integration, and robust legacy modernization capabilities. Unlike traditional approaches that require multiple tools and costly licensing, Connect/MP delivers these features in a unified platform — now enhanced with Connect/Web and Connect/AI.

It’s a smart, cost-effective investment for organizations looking to reduce operational overhead, streamline data exchange, and maximize the value of their existing mainframe infrastructure with modern, scalable access.

Whether you’re modernizing core business systems, embracing hybrid cloud strategies, enabling secure real-time data sharing, deploying web-enabled solutions, or harnessing AI to unlock deeper value from your data, Connect/MP with Connect/Web and Connect/AI delivers the performance, flexibility, and ROI your enterprise needs.

  • Broad Platform Support: Deploy as a standalone solution on z/OS, z/Linux, Linux x86, Windows, and macOS.
  • Client-Server Flexibility: Operates in standalone or client-server mode, enabling real-time cross-platform connectivity for file transfer and application integration.
  • Efficient Development: A shared codebase allows for faster updates and a consistent feature set across platforms, reducing complexity and improving supportability.

Whether you're running legacy systems or modern infrastructure, Connect/MP adapts to your environment — ensuring seamless interoperability across your enterprise.

Connect/MP › Technology

Built for Today. Ready for Tomorrow.

Most modernization strategies force a choice: rebuild from scratch, or stay where you are. Connect/MP is built on a different premise — that your mainframe is not a liability to work around, but a high-performance foundation worth extending.

“Built for Today” means your production workloads run on proven, battle-tested infrastructure — compression, cross-platform data exchange, USS integration, client-server connectivity — all performing reliably at enterprise scale, right now.

“Ready for Tomorrow” means that same platform already speaks the languages of modern IT. Browser-based access without a JVM. REST APIs without a middleware layer. AI inference running natively on z/OS. Not on a roadmap — shipping today.

The result is a platform that grows with your organization’s ambitions without requiring you to abandon what already works. No rip-and-replace. No architectural gamble. Just continuous, compounding value from a single unified suite.

The mainframe wasn’t left behind. It was ready first.
