Human Firewall 2.0

For twenty years, we've been teaching people how to spot a fake. Artificial intelligence has just made that advice dangerously outdated. Remember when a suspicious email was easy to recognise? The spelling mistakes, the strange wording, the slightly unconvincing request from someone claiming to be your bank? Today, AI can write a flawless email in your boss's style, clone a familiar voice and build an entirely believable digital identity. The clues we've relied upon for decades are disappearing. The problem isn't that people have become less careful. It's that the evidence they've always relied upon is no longer reliable. In Human Firewall 2.0, Rob May argues that cybersecurity has fundamentally become a judgement problem, and that the answer isn't another awareness course or a longer list of things to look out for. It's time to upgrade the way we think. Through ten accessible, thought-provoking conversations, Rob introduces HumanOS, a practical approach to developing better judgement in an age when appearances can no longer be trusted. You'll discover why our natural instincts can work against us, why slowing down at the right moment can be more valuable than another layer of technology, and how to build cultures where people feel confident questioning unusual requests and speaking up when something doesn't feel right. This isn't a technical cybersecurity manual, and you don't need to understand how AI works to benefit from it. It's a book for business leaders, managers, trustees and anyone who wants to make better decisions in a world where technology is becoming extraordinarily good at appearing human. Technology protects systems. People protect decisions. And in the age of artificial intelligence, that distinction has never mattered more.
