RES IT, a RES Group company, has been mentioned in Gartner’s The State of the IBM Mainframe in 2026, published on April 16, 2026. The report examines developments in the IBM mainframe market and the strategies organizations are adopting to optimize the operating costs of their core platforms.
According to Gartner, after years of predictions that the mainframe would eventually be phased out, many organizations are changing course. Mainframe exit initiatives are declining, while investment in modernization is growing to make these environments more resilient and sustainable. Mainframes remain strategic for applications built around stable, long-running processes with stringent security and data integrity requirements.
The report mentions RES IT among the companies with expertise in ISV swap projects – migrations between solutions from different software vendors -and MIPS usage optimization. RES IT is cited alongside major international IT services providers including DXC, Eccox, GTSG and Kyndryl. These projects help organizations demonstrate that mainframe environments can be managed more efficiently and sustainably. They can also strengthen confidence in the platform among non-technical stakeholders.
An Important Mention for RES Group
For RES IT and the wider RES Group, this mention represents significant recognition of the expertise developed in the mainframe field. It also confirms the company’s role as a specialized partner for organizations seeking to govern, modernize and optimize their mainframe environments without necessarily embarking on radical, high-risk transformation programs.
Federico Bonelli, CEO of RES IT, commented:
“In recent years, we have engaged with Gartner to assess our position against leading competitors in the market. We are proud to see that, according to independent expert analysis, our quality and reliability stand alongside those of the most prominent players in the international market.”
For many years, RES IT has supported organizations in managing complex information systems through a pragmatic model focused on operational continuity, cost efficiency and maximizing the value of existing technology assets. As the mainframe is increasingly viewed not simply as a legacy of the past but as a cornerstone of hybrid IT, the ability to improve costs, performance and operational sustainability is becoming more strategically important.
The mention in the Gartner report reinforces the relevance of this model. Modernization does not always mean replacement: it means identifying where to intervene to deliver tangible, measurable benefits aligned with business requirements.
