Mainframe-as-a-Service

Get more value from the mainframe you depend on. Ensono combines flexible mainframe hosting, management and support with three delivery models designed to strengthen resilience, improve connectivity to the rest of your environment and create a practical modernization path.

Let’s talk

Run the Mainframe for Today. Make it More Valuable for Tomorrow.

Ensono’s Mainframe-as-a-Service (MFaaS) changes who runs the platform, not what it does. It brings specialist expertise and established operational practices to keep critical systems running, while creating a foundation to evolve and modernize the environment around your priorities

Why Choose Managed Mainframe Services?

Reduce Costs and Operational Complexity

Avoid the cost and complexity of another mainframe hardware refresh, while simplifying software, licensing, maintenance and day-to-day operations. Ensono provides clearer accountability and more predictable costs, reducing the operational burden on your team and freeing up resources for higher-value priorities.

Add Expertise Across Your Wider Environment

Ensono combines deep mainframe expertise with cloud, application, data and security capabilities. This helps your teams address issues across platform boundaries and improve the environment you have, with the full estate in view to make evidence-based decisions about where modernization can create value.

Build Resilience into the Way the Environment is Run

Resilience is built into the operating model, not left to an SLA. Proactive monitoring, AI-assisted operations, and experienced specialists help identify and address potential issues before they cause disruption. The result is earlier intervention, faster recovery and continuous improvement in how the environment is run.
