The Defender’s Program for a Post-Mythos World

Written for CISOs of regulated enterprises. The framework can be applied broadly, but the specific recommendations assume a maturity floor. 

In this piece 

• The threat. The capability to discover previously undiscoverable zero-days is now shared across multiple frontier models. The responsible labs gated their releases. The ones who care less did not. The defender consequence is the same either way. 
• The asymmetry. AI-powered attackers operate with infinite parallel agents, sub-minute speed, comprehensive knowledge, and marginal cost approaching zero. Defender teams operate with 514K unfilled positions, 30-minute median triage, six to twelve month onboarding cycles, and flat budgets. 
• The framework. Four areas to rethink: Exposure Management, Secure Architectures, Security Operations, and Cyber Resilience. Using AI for security is no longer a nice-to-have. It is a required thread across all four. 
• Before Friday. Schedule the tabletop with legal, audit, and CAB. Pull the top fifty internet-facing assets into a single ASM view. Stand up an AI-aided code review pilot. None of this requires Glasswing access. 
• The scorecard. Four numbers reported quarterly to the board, one per shift.
