Nick Mitropoulos teaches defenders the same detection strategies he used while leading global SOCs and incident response teams, distilling these lessons into SANS SEC555TM: Detection Engineering and SIEM AnalyticsTM, the course he authored and primarily teaches at the SANS Institute, alongside SEC301 and SEC401. As lead instructor, he helps students design resilient pipelines, craft high-fidelity analytics, and validate defenses against real adversary behavior. In addition to his teaching, Nick serves as CEO of Scarlet Dragonfly, where he advises organizations worldwide on security operations, SIEM optimization, and adversary resilience.
