Panel Discussion: From threat-intel to tested defense, the adversary simulation playbook

13:15-14:00 PDT | Friday, Aug 7th 2026 | DEF CON Creator Stage 3, Las Vegas Convention Center
Panel Discussion

Panel with: Cheryl Biswas

Abstract

Knowing who is coming for you is only half the fight. The real work is turning that knowledge into defenses that actually works. This panel walks through the full playbook, from raw threat intelligence on state-sponsored actors and other adversaries, to emulating their tradecraft, to validating whether your defenses can really stand up to it.


Our panelists bring hands-on experience across adversary simulation, threat intel, and purple teaming to talk about what it takes to move from a report on paper to a tested, measurable defensive posture. The panel will dig into how to prioritize the threats that matter to your organization, how to faithfully replicate real adversary behavior instead of chasing generic checklists, and how red and blue working side by side turns every simulated attack into a lasting defensive victory. Whether you are defending against nation-state operators or opportunistic criminals, the goal is the same! Stop guessing about your defenses and start proving them. Join us for a practical conversation about closing the gap between intelligence and action.
