Built-in AI Security Is a Sensor, Not a Solution

The McKinsey breach didn't happen at the model layer. No jailbreak, no prompt injection. The vulnerability was exposed API documentation, 22 unauthenticated endpoints, and SQL injection hidden in JSON key names. An AI agent found it in two hours. The most dangerous finding — 95 writable system prompts — could have silently corrupted every answer the platform delivered. Built-in AI security is one sensor. Securing AI means seeing across the full stack: model, infrastructure, data, identity, integrations. Not just the layer your provider happens to own.
