Welcome to my website. I am a Swiss security engineer and web application firewall expert working at netnea.com . I studied History and Computer Science and graduated with a PhD in Medieval History . I continue this interest with my commitment to the Company of St. George , a medieval reenactment group, that I directed for over ten years.
On this website, you will find links to my work in information technology and also texts and publications around history . Outside of that, there are also two or three interviews and portraits .
I am the author of the ModSecurity Handbook (2ed) and I co-lead the OWASP ModSecurity Core Rule Set (CRS) project that runs on millions of servers globally. Furthermore I serve as the program chair of the Swiss Cyber Storm conference .
