Web Application Firewall – Friend of your DevOps pipeline?

Web Application Firewalls (WAF) often raise concern about false positives, latency and other potential production problems. In addition, it is often said, that DevOps and WAF do not fit together. That is a pity since the WAF helps to protect us from web application attacks, like those described by the OWASP Top Ten. But what if you could ensure that introducing and using a WAF went smoothly?

I will show how to integrate a WAF with WAF testing automation into a continuous integration (CI) pipeline. This pipeline ensures that developers receive early and often feedback about their WAF, saves them time and headaches down the line. In fact, DevOps, testing and automation only make sense if all components are part of the process.

Needless to mention, I as an [OWASP Core Rule Set (CRS)](https://coreruleset.org) developer and enthusiast introduced the CRS to [Puzzle ITC](https://www.puzzle.ch/) when I joined them in 2019! By providing YAML templates, we want to make it easy for developers to introduce WAFs into projects.
