When familiarity creates blindness: Rethinking insider threat, leadership influence and the future of trusted workforces

In this episode, we explore one of the most overlooked vulnerabilities in today’s organisations: the way familiarity, comfort and trust can blind leaders to emerging insider-related risks.Drawing on recent NPSA research and Pentagram Advisory’s insights, we unpack why insider threat often feels “unlikely,” how the psychological contract shapes behaviour long before policies do, and why point-in-time checks provide only the illusion of safety.We examine the cultural resistance to insider threat programs, the language barriers that shape organisational acceptance, and the leadership blind spots that allow early warning signs to go unnoticed.Most importantly, we discuss how shifting from blind trust to informed trust can strengthen culture, governance and accountability — and what it takes to build a truly trusted workforce in an evolving threat landscape.If your organisation is reassessing its people-related risks, workforce suitability, or insider threat maturity, this episode provides a clear, practical lens to recalibrate assumptions and enhance preparedness.
