3/ We’re also helping customers secure and govern their agents at scale. Over 50M agents are now in A365, up 30% QoQ. We are bringing together Windows + Agent 365 so agents can work within secure boundaries on-device using MXC. Agents like OpenAI Codex, Anthropic Claude Code, and Meta Muse are all adopting it. And with Perception, we’re separating intelligence from authority, enforcing identity, permissions, monitoring and containment outside the model itself. We’re encouraged by the feedback from preview customers.
