NAB’s AI build-out has been aggressiveIn April 2026, the bank launched its first dedicated AI Science team, led by George Mathews, with a mandate to design and evaluate agentic AI systems that can operate safely inside one of the most heavily regulated industries on earth. The AI agents cut that to approximately 1 minute, a 97% reduction in review time. By March 2026, agentic AI applications for customer workflows had reportedly hit a 90% adoption rate across the bank’s divisions. Why security testing for agentic AI is differentAgentic AI systems are designed to take actions autonomously, processing documents, initiating workflows, interacting with customers, sometimes chaining multiple steps together without waiting for human approval at each stage. If an agentic AI hallucinates, it might already be three steps into executing something nobody asked for.
