Atos and Microsoft have expanded their strategic partnership to accelerate the adoption of agentic AI across Atos’ global operations, with the technology services company deploying Microsoft 365 Copilot to its entire workforce of 56,000 employees in 54 countries.

The rollout marks one of the largest enterprise-wide deployments of Microsoft’s AI workplace tools to date and positions Atos among the earliest global organizations to adopt the newly available Microsoft 365 E7 platform, which combines Microsoft 365 Copilot, Microsoft 365 E5 security and compliance capabilities, and Microsoft Agent 365 for AI agent governance.

As part of the initiative, Atos will embed AI capabilities into everyday productivity applications, such as Outlook, Teams, Word, Excel, PowerPoint, and SharePoint. The company is also adopting Microsoft Copilot Studio and Microsoft Foundry to build and manage AI agents for internal operations, business functions, and customer-facing services.

The deployment is designed to support Atos’ broader strategy of bringing agentic AI into regulated and mission-critical environments while maintaining strong security, compliance, and governance controls. The company said it plans to manage approximately 19,000 AI agents through a centralized framework using Microsoft Agent 365, providing oversight across user-driven agents, autonomous agents, and partner ecosystem agents.

According to Atos, the deployment represents a cornerstone of its AI transformation strategy, which focuses on agentic AI, digital sovereignty, and cybersecurity. The company intends to use its own implementation as a blueprint for helping customers adopt AI at scale across highly regulated industries, including defense, healthcare, financial services, and public administration.
