Zero-Day Exploit

A zero-day exploit is an attack that takes advantage of a software flaw before the vendor knows about it or has issued a fix. This matters for AI governance because enterprise AI systems often depend on underlying software libraries, cloud platforms, and open-source components that may contain unknown vulnerabilities, exposing your organization to compromise before patching is even possible. Your compliance and risk teams need to understand zero-day risk when assessing AI system resilience, third-party dependencies, and incident response plans.
