ModSecurity Masterclass

The Key to ModSecurity and the OWASP ModSecurity Core Rules with Christian Folini

This two-day course will help you set up an Apache webserver and install ModSecurity together with a tight ruleset. We will configure the server and talk about every single detail of the configuration to give you an expert understanding of how your server works and behaves.

We prefer small class sizes and never overbook. This course is also available as an on-site option.

Contact us if you'd like to attend this course! Future dates will be announced here.

He brings more than ten years experience in this role, specialising in Apache / ModSecurity configuration, DDoS defense and threat modeling.

Christian is a frequent committer to the OWASP ModSecurity Core Rules project, vice president of Swiss Cyber Experts (a public private partnership), member of the committee of the Swiss Cyberstorm conference and many other things.
