The person behind the posts
I’m George Coldham — a Cloud Solution Architect at Microsoft in the Security Solution area, based in Perth (Western Australia). I help teams reduce real-world risk in SaaS and AI-heavy environments, where generative and agentic AI amplify normal human behaviour into security incidents. My work sits at the intersection of threat protection, identity, SaaS, data protection, and automation — with a strong preference for controls that actually survive contact with humans.
Now
Microsoft (ANZ)
Partner with enterprise scale organisations to design and improve security outcomes across threat protection, identity, data, devices and cloud. I focus on the modern control plane: OAuth consent, session/token abuse, unmanaged browsers, and how AI tools accelerate productivity but could enable risky behaviour.
Ongoing
Global Security Community · Perth Global AI Community · Perth Microsoft Security Meetup · Perth GitHub Meetup
I present locally and internationally on emerging security topics, helping practitioners understand how new technologies and AI change risk at scale. I also build and enable professional communities — either by bringing practitioners together directly, or by creating repeatable formats and resources that others can reuse to run sustainable communities.
Always
Automation, demos, and “show me” security
I like security that you can prove. I build small tools and repeatable workflows (often using Microsoft-first approaches) to document configuration, detect drift, and turn tribal knowledge into something you can hand to the next person without a two-hour meeting.
