Christian Folini

Welcome to my website. I am a Swiss security engineer and web application firewall expert working at 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.

People know me for my comprehensive set of 12 Tutorials about ModSecurity and the Core Rule Set. All released under Creative Commons license. I also teach ModSecurity and Core Rule Set courses and I consult companies who want to integrate ModSecurity and the Core Rule Set into their services or products, also in high security setups. If that is of interest to you, then please get in touch.

Lately, I’m running a blog about my work as election worker.
