AI is changing how access decisions are made. Identities now include users, services, workloads, and AI agents operating at machine speed, exposing gaps between identity and network controls. This session introduces the Access Fabric as a unifying model that connects identity signals with device, data, and network context to deliver consistent, adaptive access for any identity, employee or AI. We will also explore how Microsoft is applying this Access Fabric internally, including the security and operational benefits achieved by unifying identity and network access.
