I’m Karl.

I currently serve as Head of Incident Response at Germany’s second-largest public authority, where I lead and coordinate the response to high-impact security incidents in complex, highly regulated environments. My work spans strategic incident leadership, hands-on technical analysis, and the design of resilient security and response processes at scale.

My background combines deep practical experience in incident response with offensive security research and secure systems engineering. I focus on understanding real-world attacker behavior, improving detection and response capabilities, and building reliable tooling for security operations.

This GitHub account is a professional workspace where I publish selected tools, scripts, and research projects related to cybersecurity, automation, and secure infrastructure. Some projects remain private due to operational, legal, or compliance requirements.

  Strategic and operational leadership of incident response for large public-sector environments.

• Offensive Security & Threat Research
