The Browser Blind Spot: Rethinking Enterprise Security

The browser has quietly become the most critical—and most overlooked—attack surface in cybersecurity. In this episode of the Brilliance Security Magazine Podcast, host Steven Bowcut talks with John Carse, Field CISO at SquareX, about the company’s groundbreaking Browser Detection and Response (BDR) technology and why legacy tools like EDR and Secure Web Gateways can’t see today’s browser-native threats.John draws on his two decades of global cybersecurity experience—spanning the U.S. Navy, JPMorgan, Expedia, and Dyson—to explain emerging risks like Syncjacking, Polymorphic Extensions, and the coming wave of AI-powered browser agents. He also shares practical steps for CISOs to reduce risk from Shadow SaaS and unmanaged devices.If you think your browser is safe, this episode will make you think again.
