I am John Kischel, Senior Cybersecurity Consultant and Speaker with a clear focus on security architecture.
My focus is on the secure design of complex IT systems, ranging from identity and Active Directory to networks and infrastructure, as well as modern security concepts. In doing so, I combine deep technical understanding with a holistic architectural perspective to identify risks early on and develop sustainable security solutions.
Alongside my work, I share my knowledge in talks, podcasts, and technical deep dives.
My ambition: Understand the system. Engineer the security.
