Our vision is simple: security should be ambient and autonomous, just like the AI it protects. As organizations accelerate AI adoption, security teams are navigating new blind spots created by the broad distribution of agents, data, and identities across different tools and platforms. Microsoft Security ’s latest updates extend visibility, control, and protection across your expanding ecosystem, from third-party apps like Claude to your cloud environments and multi-cloud infrastructure.
