As a freelance trainer and consultant, I support companies in secure software development. This includes the creation and evaluation of software architectures, for example by means of threat analyses, the development of secure code and the finding of vulnerabilities through penetration tests in real hand and head work (TAH - Tool Assisted Human). I help not only to write secure development processes, but to implement them in a feasible way. But what good is the best process if the knowledge is missing? To counter this, I give various trainings, among others for software developers and architects, which are as exciting and entertaining as they are instructive and whose contents are implementable in everyday work.
