Secure & Simple — Podcast for Consultants and vCISOs on Cybersecurity Governance and Compliance

In this Secure and Simple Podcast episode, host Dejan Kosutic (CEO of Advisera) interviews Andrew Gault (CEO of ZeroTier) about Zero Trust as a strategy and mindset rather than a single technology, shifting away from perimeter-based security to “default deny” with continuous verification. Gault outlines core layers such as identity for users and devices, policy-based scoring, encryption, and ongoing monitoring to reduce lateral movement when breaches occur. They discuss extending zero trust principles to suppliers by issuing vendor identities managed centrally, governance needs like documented access policies, change management, and least privilege, and challenges such as shared credentials and the ongoing effort to keep permissions current. The conversation also covers non-human identities for AI agents, service accounts, ownership and lifecycle management, audit expectations under SOC 2 and ISO 27001, vendor lock-in tradeoffs, and using inventories and exception reduction as practical KPIs.
