From Shadow APIs to Shadow AI: How the API Threat Model Is Expanding Faster Than Most Defenses
Security Boulevard, Wednesday, February 18th, 2026
The shadow technology problem is getting worse. Over the past few years, organizations have scaled microservices, cloud-native apps, and partner integrations faster than corporate governance models could keep up, resulting in undocumented or shadow APIs.
We're now seeing this pattern all over again with AI systems. And, even worse, AI introduces non-deterministic behavior, autonomous actions, and machine-to-machine decision-making. Put simply, shadow AI is much, much riskier than shadow APIs. And it's a problem we must deal with immediately.
