Case Study: US-Based Financial Institution achieves $10M savings and 50% increased mainframe capacity with Ensono

Mainframe modernization yields $10M savings and 50% increased capacity

US-Based Financial Institution, a long-established U.S. financial services provider, needed to maintain a secure, reliable mainframe environment while addressing a shortage of processing capacity that was slowing overnight batch runs and limiting access to key applications. The organization also wanted to modernize without moving away from its existing mainframe-based workflows, and it turned to Ensono for mainframe services support and modernization expertise.

Ensono implemented a mainframe modernization program that included transferring 34 in-house IT staff into Ensono, reducing software spend, and increasing mainframe capacity by nearly 50%. This cut nightly batch processing from about 9–10 hours to just 2–3 hours, improved availability for users, and created a more reliable environment compatible with future cloud initiatives. Over three years, Ensono helped deliver $10 million in combined savings, including $7 million on system software and $2.5 million on application software.
