Case Study: Largest Mutual Life Insurance Company achieves a fully managed mainframe transformation with Ensono

Insurance Provider Takes First Step Towards a Digital Transformation

The Largest Mutual Life Insurance Company, one of the largest mutual life insurers in the U.S., faced aging infrastructure, an outdated data center, and growing mainframe staffing concerns as it began exploring outsourcing for the first time in its 150+ year history. The company needed a cost-effective way to modernize IT operations while preserving its strong people-first culture, and it turned to Ensono for help, including managed services support.

Ensono implemented a two-phase approach: first providing Remote Infrastructure Management to stabilize the environment, then moving to a fully managed solution with new equipment and a nearby data center for latency-sensitive applications. Ensono also interviewed staff and rebadged more than half of the mainframe team, helping the client transition operations in four months, stabilize its mainframe environment, and gain early financial flexibility.
