In this episode of The Defender’s Log, host David Redekop sits down with DNS and DDI expert Andreas Taudte, who brings more than 16 years of experience in network security, DNS architecture, and threat mitigation.

Together, they unpack the real challenges organizations face with DNS, from evasion techniques and tunneling threats to the growing complexity of legacy systems and hybrid networks. Andreas explains why DNS predictability is essential, how DDI (DNS, DHCP, IPAM) has evolved, and what enterprises must do to build resilient, zero-trust-aligned network foundations.

This conversation is packed with real-world stories, practical insights, and actionable strategies for anyone responsible for securing modern infrastructures. If you touch networking, cybersecurity, or cloud architecture; this deep dive is for you.
