The RSA Conference is the largest and most prestigious gathering of cybersecurity professionals in the world. A keynote slot at RSA is one of the most coveted platforms in the industry — reserved for the thinkers and builders who are genuinely shaping the direction of security. Stuart McClure's 2012 keynote, "Securing the Unsecurable," was a landmark moment in his career and a defining statement about the security challenges facing a world of proliferating connected devices.
The unsecurable in question were the embedded systems, industrial controls, and specialized computing platforms that had never been designed with security in mind. By 2012, these systems were increasingly networked — bringing both productivity and unprecedented attack surface. Stuart's thesis was that the security industry's existing playbook — signatures, perimeters, reactive defense — was fundamentally inadequate for this challenge, and that what was needed was a new approach grounded in mathematical models of system behavior.
This was the intellectual foundation that Stuart was simultaneously turning into a company: Cylance, founded the year before, was building the AI-native security platform that would prove the argument. The keynote at RSA 2012 was both a diagnosis of the problem and an implicit demonstration that a solution was being built.
Stuart's ability to communicate complex technical arguments to mixed audiences of practitioners, executives, and policymakers — developed through years of briefing boards, testifying to Congress, and writing the foundational text of the industry — was on full display at RSA 2012. The keynote is widely remembered as one of the most compelling security presentations of its era.
