EY launched enterprise-scale agentic AI embedded across its entire Assurance division — 130,000 professionals conducting 160,000 audits in 150+ countries — making it one of the largest single deployments of agentic AI in professional services. The multi-agent framework runs on Microsoft Azure, Foundry, and Fabric, integrated into EY Canvas, the firm's global audit platform that processes 1.4 trillion journal-entry lines per year. The rollout handles task orchestration, risk identification, and real-time access to accounting standards guidance, with full end-to-end coverage of all audit activities targeted by 2028. EY was named to the inaugural Frontier Firm AI Initiative, one of 14 organizations recognized for deploying advanced AI at enterprise scale.
