Fujitsu Accelerates Developer Productivity and Security Across 120,000 Users with Microsoft Dev Box and GitHub Copilot

Fujitsu, a multinational technology and professional services company with over 120,000 employees, faced significant operational inefficiencies in its development environment. The company's previous approach required operations teams to purchase and configure physical devices for each developer and project, with developers spending approximately one week fine-tuning configurations for each new assignment. This manual hardware-centric model created delays, increased security vulnerabilities, and limited flexibility for a globally distributed workforce managing complex, confidential projects across multiple client and nation-specific compliance standards. To maintain competitive advantage while accelerating time-to-market, Fujitsu required a cloud-based platform that could deliver both speed and security without compromising developer productivity.

Fujitsu deployed Microsoft Dev Box, cloud-based developer workstations that eliminated hardware procurement and configuration overhead, combined with GitHub Copilot, an AI-powered coding assistant, and Microsoft Entra ID for identity governance. Microsoft Dev Box enabled project-specific, customizable environments while maintaining standardized security policies across the entire developer base. GitHub Copilot accelerated coding cycles by automating repetitive tasks such as testing, validation, and error resolution, allowing developers to focus on innovation. Microsoft Entra ID provided seamless single sign-on and granular access controls, ensuring only authorized personnel could access each project's resources. The cloud-based infrastructure eliminated weeks of setup time per developer per project, reduced information leakage risk through isolated virtual environments, and standardized governance across diverse compliance requirements.

After one year of Microsoft Dev Box deployment and six months with GitHub Copilot, Fujitsu's pilot group of 2,400 developers achieved measurable results that will scale significantly as full enterprise adoption continues throughout 2025. The combined solution has reduced developer workload by 20%, with expected annual savings reaching 375,000 developer hours as the platform rolls out organization-wide. Standardized provisioning accelerated deployment speed, reduced security configuration complexity, and eliminated firmware update burdens for development teams. By centralizing identity management and project governance, Fujitsu lowered information leakage risk while delivering faster solutions to international customers, demonstrating that intense security standards need not compromise operational velocity or developer productivity.
