On May 16, 2025, an EF3 tornado struck St. Louis. The warning sirens never sounded. The independent after-action report found cascading failures: untested alert systems, a single-point-of-failure repeater, unclear ownership between agencies, a 22-year-old emergency plan, and siloed teams who couldn't coordinate under pressure. Every failure maps directly to what we see in identity incident response today. Drawing from the official investigation, IR Readiness Scorecard data showing 99% of organizations score "Not Ready," and the compressed attack timelines of AI-accelerated threats, this session explores what disaster response teaches us about rebuilding identity infrastructure.
