Fraud doesn't always announce itself with obvious warning signs. Quite often, it shows up wrapped inside something that feels routine — a purchase you've made before, a link that looks legitimate, a message that arrives at just the wrong moment. Nothing feels suspicious, so your guard stays down. By the time questions start forming, the transaction is already done.

My guest today is Iremar Brayner. He's spent more than 15 years working in fraud prevention and risk management across payments, retail, ride-hailing, fintech, and digital marketplaces. In his role at G2A, he leads fraud strategy for one of the world's largest digital entertainment platforms, where speed, approval rates, and loss prevention are constantly pulling against each other.

We discuss why scams continue to work despite smarter tools, how "friendly fraud" complicates the picture, and why digital goods create very different risk patterns than traditional retail. We also get into automation, AI-driven decisions, and what it really looks like to manage fraud in real time.
