Future-Proofing Healthcare Insurance to Save $50M

How did a large health insurer save $50M over 5 years — and secure its infrastructure for the future? Here’s the story.

In healthcare, reliability isn’t optional — it’s a lifeline. When critical systems age, the risks extend far beyond IT — they reach the members who depend on them. This large health insurer was battling rising mainframe costs and a growing skills shortage that threatened the stability of its entire infrastructure. Partnering with Ensono and adopting Mainframe-as-a-Service, they transformed their approach by cutting costs, upgrading hardware, and freeing their teams to focus on what matters most.

What were the results?

• $50M saved in mainframe costs over 5 years — a 40% reduction
• Hardware upgraded and secured, protecting members and operations
• Teams freed to focus on delivering excellent service to members

Why does this matter? For health insurers, mainframe reliability is directly tied to member outcomes. Mainframe-as-a-Service gives large insurers a proven path to reducing cost and risk simultaneously — without disrupting the systems that millions of members depend on every day.
