Black Hat USA 2026 | Keynote: The End of Rare Defending When Offense Is Cheap

David Weston discusses the shift from stopping rare cyberattacks to building resilient systems capable of withstanding constant, cheap, AI-driven offensive pressure.

What happens when advanced cyberattacks are no longer rare, but routine? In the Black Hat USA 2026 Keynote “The End of Rare: Defending When Offense Is Cheap”, David Weston tackles the growing imbalance between increasingly affordable offensive capabilities and the rising demands placed on defenders to secure complex environments. As AI, automation, and widely available offensive tooling continue to lower the cost of attack, the challenge is no longer how to stop every threat. It's how to build resilient systems that can withstand constant pressure. Walk away with practical insights, a clear picture of the threat-landscape shift, and a concrete case for emergent defense in the AI era.
