As AI agents become essential to enterprise software, seamless and secure communication between them is critical. That’s why Microsoft supports the open Agent2Agent (A2A) protocol, which is now coming to Azure AI Foundry and Copilot Studio.

What A2A Enables

A2A enables intelligent agents to securely exchange goals, share state, and trigger actions across platforms and organizations without relying on a centralized system. This means better interoperability, stronger governance, and greater flexibility for developers and IT leaders alike.

Expert Insight: Why This Matters for Business

“Microsoft’s embrace of A2A is a game changer,” said Art Pugach, Chief Technology Officer. “The ability to allow Copilot Studio and Azure AI Foundry to communicate securely across platforms via an open protocol structure allows for greater flexibility in design while maintaining a secure way to keep customers in control of their data.”

A Step Toward the Future of Composable AI

Microsoft’s investment in open agentic systems reflects a larger shift: enterprise AI is becoming composable, adaptive, and distributed. A2A helps make that vision real by connecting agents securely across clouds, models, and teams.
