In this landmark 99th episode of the Cybersecurity Readiness Podcast Series, Dr. Dave Chatterjee is joined by Denny LeCompte—CEO of Portnox (https://www.portnox.com/) and a former SolarWinds executive—to examine one of cybersecurity’s oldest yet most persistently exploited challenges: access control.

Despite decades of investment in passwords, MFA, and perimeter defenses, breaches rooted in access failures continue to dominate headlines. Drawing on firsthand experience—including lessons learned from the SolarWinds Sunburst breach—LeCompte explains why password-centric security models are fundamentally misaligned with human behavior and modern digital environments.

Together, Chatterjee and LeCompte argue for a decisive shift toward passwordless, device-centric, zero-trust access models that assume human fallibility, eliminate implicit trust, and dramatically reduce attack surfaces. Framed through Dr. Chatterjee’s Commitment–Preparedness–Discipline (CPD) lens, the episode reframes access control not as an IT configuration issue, but as a core pillar of cybersecurity governance, business resilience, and competitive survival.
