Passionate developer building open-source cybersecurity tools used worldwide.

I'm Théo Geffe, an IT developer based in the Grand Duchy of Luxembourg. I work at CIRCL — the Computer Incident Response Center Luxembourg — the national CERT responsible for cybersecurity incident response.
My work sits at the intersection of web development and cybersecurity. My flagship project, rulezet-core, is co-copyrighted with CIRCL and EU-funded under the FETTA project. Its live version — rulezet.org — indexes over 122,000 detection rules.
Highly adaptable and deeply motivated, I was publicly recognized for my hard work on rulezet releases at the hack.lu workshop. Outside of code, I'm a passionate drummer and sports enthusiast.
