Greig Arnold is a Partner in Cyber Security who brings a practitioner’s mindset to the evolving challenges of cyber risk, resilience, and emerging technology. His perspective is shaped by more than a decade of hands‑on experience as a CISO and CIO defending security capabilities, complemented by extensive experience advising organizations on complex cyber transformations.
Greig’s work explores how modern threat dynamics—particularly insider threat—are reshaping enterprise risk. Drawing on real‑world operational experience, he helps organizations understand human‑centric risk across employees, third parties, and digital identities, and design detection, governance, and response models that reflect how environments actually operate, not how they are diagrammed.
A central theme of Greig’s thought leadership is operationalizing artificial intelligence securely and responsibly. He advises leaders on embedding cyber risk management, resilience, and accountability into AI adoption so innovation can scale without introducing unmanaged exposure. His focus is on making AI security practical, measurable, and defensible in production environments.
By combining practitioner insight with strategic advisory depth, Greig offers a grounded, credible voice in cybersecurity—helping organizations move from theory to execution while maintaining trust, resilience, and momentum in a rapidly changing digital landscape.
