Cloud Solution Architect @ Microsoft | Zero Trust & Identity at Enterprise Scale | International Speaker, Educator & Community Founder

George Coldham is a Cloud Solution Architect at Microsoft, working with enterprise and public-sector organisations to design and operate secure cloud and identity architectures at scale. His work focuses on Zero Trust, identity as the modern security control plane, and the practical realities of securing SaaS, cloud platforms, and emerging AI systems in complex environments. George specialises in helping organisations reduce real-world risk without undermining productivity or user experience. Alongside his technical role, George is an experienced international speaker, educator, and community organiser. He regularly presents at industry conferences, bootcamps, and meetups, translating complex security concepts into practical guidance for practitioners and decision-makers. George is the founder of Global Security Community, the lead organiser of the Perth Microsoft Security Meetup, and an organiser within the global AI and developer community. He brings a practitioner-led, evidence-based perspective to his talks, drawing on real customer scenarios rather than vendor theory or marketing narratives. His speaking topics include Zero Trust beyond the marketing slides, identity-driven security, cloud and SaaS security in practice, and designing security architectures for humans as well as systems.
