Ensono named a Leader by ISG across key Mainframe Services for the U.S. Public Sector

The 2026 ISG Provider Lens™ Mainframe – Services and Solutions report recognizes Ensono as a Leader in the U.S. Public Sector across Mainframe-as-a-Service (MFaaS), Mainframe Technology Consulting, and Application Modernization. 

AI is changing how modernization gets done. It’s no longer about moving off the mainframe—it’s about making it work smarter. That’s why organizations are shifting toward AI-enabled, hybrid approaches that improve performance, resilience, and long-term sustainability across mission-critical systems. 

From optimizing today’s environment to enabling what’s next, Ensono helps public sector agencies modernize with less risk, more flexibility, and real results across regulated, mission-critical environments. 

The ISG Provider Lens™ report evaluates leading providers based on their ability to deliver secure, scalable mainframe services, with a focus on AI adoption, hybrid cloud integration, and resilience for public sector organizations. 

Why Ensono Stands Out:

• Public sector proven: Supporting mission-critical systems across 15 U.S. states 

• Deep mainframe & cloud expertise: Bridging legacy and modern with a balanced approach 

• Flexible modernization paths: Optimize, integrate, or transform without forced tradeoffs 

• AI-driven operations (AIOps + GenAI): Predict issues, reduce downtime, and improve performance at scale 

• Built to scale: Managing millions of MIPS across a growing client base 

“Ensono’s mainframe application modernization business complements its leading MFaaS business, expanding the value the company can provide agencies beyond hosting mainframe environments.”
