Christoph always loved to interact with software systems, even more so in unintended ways. He studied Applied Computer Science in the south of Austria, focusing on the detection of server-side request forgery in his Master’s thesis. As a demo environment for this thesis, he created a small distributed application called “Vogelgrippe” which was then later extended for various other use cases until being renamed to Unguard and finally gifted to the community as an Open-Source playground. Currently, he is working in the Application security team at Dynatrace, where he helps build a wide suite of security-related software.
