NAB Nexus keeping customers safe in an AI driven threat environment 22 June 2026 Australians are operating in a more complex and persistent threat environment than ever before, with scams, fraud and cyber‑attacks increasing in scale, speed and sophistication.  For many Australians, the impact is real. It can affect access to their money, disrupt payments and undermine confidence in services people rely on every day. In response, NAB has launched NAB Nexus, a 24/7 integrated operations hub designed to keep the bank ahead of rapidly evolving AI-enabled threats, protect customers and support critical banking services.  NAB Nexus brings together frontline responders across technology, cyber security, fraud, payments and physical security into a single, always on operation. NAB Group Chief Executive Officer Andrew Irvine said NAB Nexus is integrating all those capabilities into one place so that we can move faster in sharing information and identifying threat actors in real-time. “AI is going to do a lot of great things for how we live and how we work, but at the same time, AI is also going to help criminals and their threats much faster than when it was a human-only environment,” Mr Irvine said. “We know that we need to keep our customers’ money and data safe, and that’s what we intend to do. We’re better when we work together. To mitigate this threat, it must be a team sport.” NAB Chief Security Officer Sandro Bucchianeri said the threat environment had become more complex, persistent and connected, reinforcing the need for a connected, real-time response. “These threats don’t sit neatly in one box. A scam attempt, fraud event, cyber incident or payments issue can quickly intersect. At the same time, new technologies like AI are lowering the barrier for criminals to operate at scale,” Mr Bucchianeri said.  “NAB Nexus gives us a more connected way to see what is happening, make decisions faster and act earlier to help protect customers and keep the bank safe”. The need for stronger resilience is clear. Australians continue to face a growing wave of scams and cybercrime, with combined scam losses reaching $2.18 billion in 2025, and the Australian Signals Directorate (ASD) receiving more than 84,7000 cybercrime reports in FY2024 – 25.  The ASD has warned that cybercrime continues to challenge Australia’s economic and social prosperity, with critical infrastructure an attractive target because it underpins essential services.   NAB has invested more than $900 million in FY25 in fraud, scams, cyber and financial crime protections, including investments in AI and advanced analytics to strengthen detection and threat disruption. NAB Nexus is designed to support a threat environment that doesn’t stop at the end of the working day. Operating 24 hours a day, 365 days a year, the hub supports continuous monitoring, faster handover and more coordinated response.  For further information on how to protect yourself from fraud, scams and cybercrime visit nab.com.au/security.
