You built for speed. They exploit at speed. Streaming architecture closes the batch pipeline attack surface. It introduces a new one: the speed paradox. An agent that receives real-time context, decides in milliseconds, and acts immediately has no natural friction. If an adversary triggers a wrong decision, the harm propagates at machine speed—faster than any human can intervene. This talk exposes the speed paradox as an attack surface, demonstrates how an adversary exploits the governance gaps in streaming AI infrastructure, and presents the architectural mitigations that close them: action intent events, policy-as-code enforcement, and immutable audit trails embedded in the event stream. Attendees leave with a governance framework—define boundaries, embed enforcement, instrument accountability, assign ownership—that doubles as both defense and adversary detection.
