Before Audi, Kai worked for more than 12 years in the steel industry at the engineering company SMS Group, where he designed and implemented defensible LANs for enterprise and ICS environments in-house as well as for customers' plants. The steel industry was also where Kai delved into Network Security Monitoring and DFIR, building security monitoring solutions for company and customer sites and performing incident response in Europe, Asia, and the United States.
In the little free time that is left between working in his DFIR job and as a SANS instructor, Kai loves to travel the world, especially mountain regions where climbing, hiking, and skiing look promising.
Kai holds an MA in Computer Science and English and American Literature.
“Kai is a very detailed and expert trainer. He helped me understand what is possible to do at a technical level.” - former ICS515 attendee
