Case Study: a leading telecommunications provider achieves seamless mainframe access with Macro 4 Tubes for z/OS

How an IBM Session Manager user migrated to Tubes for z/OS in a single afternoon

A leading telecommunications provider with over 30 million customers faced a critical business challenge when IBM Session Manager, the software used by 35,000 employees to access mainframe applications, was withdrawn from the market. They needed to find a 100% compatible replacement to eliminate the catastrophic risk of service interruption and ensure seamless access for thousands of users and robotic processes.

The vendor, Macro 4, implemented its Tubes for z/OS solution as a direct, no-risk replacement. The implementation was remarkably swift, taking just one afternoon with no complex configuration or changes needed, which minimized disruption and cost. The solution provided uninterrupted, user-friendly access to over 3,000 mainframe applications, ensuring business continuity and operational efficiency. Macro 4 delivered a seamless transition that required no user training and freed the company's internal team to manage the entire migration without external consultants.
