Cyber Assurance, Turned Into How Software Gets Built.
AIEOS is built by Dr John Mackenzie — a cyber assurance and secure-AI specialist with 30 years across technology, governance and business. He has advised 14 billion-dollar enterprises, assessed risk across assets exceeding US$300 billion, and hardened critical infrastructure across power, water and gas.

Who Is Dr John Mackenzie?
A Brisbane-based cyber assurance and advisory specialist — and a hands-on AI engineer. His 30 years span 18 years in commercial banking, manufacturing operations, Commonwealth advisory to the resources sector, enterprise cyber GRC at scale, and now secure-AI engineering.
His posture is deliberately an assurance one, not a design one: making sure what actually gets built and deployed meets the bar — without becoming a handbrake on delivery. That is exactly the job AIEOS does for AI-built software.
Assurance At Real Scale.
Evidence Before You Call It Done.
John treats cyber assurance as a defensibility problem — not whether a control existed, but whether proportional evidence existed before failure, and whether the sequence of decisions would survive regulatory and forensic review.
For AI, he built the discipline he calls AI Lineage & Chain of Custody — tracing which model, prompt, dataset, tool, agent and human touched an output, when, and under what authority, so AI-assisted decisions stay attributable and defensible rather than opaque.
AIEOS is that discipline turned into how software gets built. An AI workforce — with every unit of work scoped to a testable bar, assured at the right gates, and reaching Done only with recorded evidence: independent review, a human decision on the record, and a tamper-evident journal. Governance that paces delivery instead of throttling it.
He Researches Why Governance Fails.
Most practitioners apply frameworks. John has spent years publishing original research on why framework-compliant organisations still fail catastrophically — six independent papers and three books, including Black Snow and HACKED!.
