Threat modeling often fails in fast-paced teams spaghetti diagrams, generic threats, models no one reads. I’ve been there. This talk is my journey from theory-heavy modeling threats in Europe to fast, focused practices that teams actually use. No STRIDE deep dive here, just real stories, quick wins, and simple habits that made threat modeling part of delivery, not a blocker. Not perfect. Not exhaustive. Just useful enough to catch what matters, when it matters.
