AI works in cybersecurity when the problem is scale — classifying dark web content, detecting reuse patterns across billions of credentials, parsing stealer logs. It fails when the problem is judgement: autonomous incident response in critical infrastructure, zero-day detection drowning in base-rate false positives. Most "AI-powered" products are rules and regex under a dashboard. Buy outcomes, not labels — and keep humans in the loop where mistakes have physical consequences.
