Hi there, I'm Martin

I work as a Senior Cyber Security Engineer at KION Group and am Co-Founder & CTO at MainDefense GmbH.

My day-to-day work sits between incident response and systems architecture: investigating incidents, connecting detection to decision, and building the platforms that do the heavy lifting.

What I work on

• Agentic response & security platforms - Architecting autonomous analysis and incident response systems, focused on the harnesses and guardrails that make them safe to run.
• Incident response & forensics - Active incident handling (SANS FOR508), detection engineering, and turning post-mortems into actual engineering fixes.
• IT & OT deception - Leading product architecture at MainDefense for our deception platform DeepSea and PhishEye.
• Pragmatic governance - Translating technical risk for leadership and building a modern, AI-enabled ISO 27001 ISMS.
