About

I’m an experienced cybersecurity CTO who builds products that turn messy telemetry into clear, automated actions that hold up under real attack conditions. In my capacity as CTO at BullWall, I'm responsible for technology strategy and product direction. I work hands-on with customers facing high-impact ransomware and operational risk, helping security teams prioritize controls that reduce blast radius, constrain lateral movement, and restore control - fast. I hold 20+ years of experience across law enforcement, healthcare, and global enterprise environments, including work with the Danish National Police. Over the past 15 years I’ve served as CTO in security software, leading AI initiatives, threat labs, and research-driven product engineering in close collaboration with demanding SOCs. Core themes • Ransomware containment and operational resilience: limit spread, maintain operations, and recover with discipline. • Detection and response automation: structure events and context so actions are explainable and repeatable. • Secure-by-design delivery: threat modeling, vulnerability management, and compliance-aware engineering (GDPR, NIS2). • Geopolitical threat realism: designing for supply-chain abuse, credential-driven intrusion, and hybrid disruption. I hold a degree from ITU Copenhagen and have completed executive programs at MIT. I advise and speak at international security forums including Europol, Interpol, and NATO, and across critical infrastructure engagements in Europe and Ukraine. I’ve also mentored PhD programs that bridge academic research and operational security.
