Harm Griffioen is a cybersecurity researcher-practitioner and founder with 11 years of experience bridging academia, government, and entrepreneurship. Holding a PhD from TU Delft, he researches and teaches cyber threat intelligence and network security while leading GriffinGuard to translate research into operational defenses. His background includes hands-on threat analysis at the Dutch Ministry of Defence and doctoral work at Hasso Plattner Institute, giving him practical insight into adversary behavior and intelligence workflows. Known for combining rigorous academic methods with applied security engineering, he routinely brings AI, networking, and advanced analytics into threat investigations. Based in South Holland, he’s equally comfortable lecturing courses as he is building tools that close the gap between research and real-world cyber operations.
