For Shojiro Shiratori, Head of the Enabling Technologies Division, Corporate Digital Unit (CDU) at Fujitsu, overall standardization is key to nailing down security along with a range of other benefits. “Standardization has enhanced our provisioning speed,” he says. “It also makes it much easier to control governance for each project. This means that we can deliver our solutions much faster, especially products under development for international customers. And think of the benefits of standardization applied across 120,000 users—we’re beginning to experience significant cost savings.”  

As a cloud-based solution, Microsoft Dev Box creates a beneficial synergy between security enhancements and operational efficiencies. “With Microsoft Dev Box, we have standardization that we’ve never had before,” continues Shiratori. “Thanks to the built-in security, developers no longer deal with firmware updates and other time-consuming tasks.​” 

The CDU complements the secure environment it has created with Microsoft Dev Box by applying the security capabilities in GitHub Copilot.

Transforming the world—with safety and speed

After just one year of Microsoft Dev Box use, Fujitsu has made enormous strides toward the more easily secured, productivity-first development environment it needs to meet its long-term goals. Having introduced GitHub Copilot just six months later, it’s already realizing substantial benefits. The company’s pilot group of 2,400 developers using GitHub Copilot are spending less time to achieve more. As the full development team comes on board throughout 2025, those savings will magnify. “Our developers using Microsoft Dev Box and GitHub Copilot decreased their workload by 20%. Over a year, we expect that to total 375,000 hours saved—a massive benefit for Fujitsu,” says Shiratori.
