AI-assisted attacks are compressing attack timelines from months to hours, rendering traditional perimeter-based security models obsolete. The core argument is that enterprises must shift from breach prevention to breach readiness by defining a Minimum Viable Digital Enterprise (MVDE) — the critical subset of systems that must remain operational during an attack. EDR-integrated microsegmentation (using existing tools like CrowdStrike, Microsoft Defender, or SentinelOne) enables rapid containment of lateral movement, shrinking blast radius and buying defenders time. The piece calls on CISOs to assess breach readiness, define their MVDE, and build SOC procedures that quarantine breaches before they reach crown-jewel systems.
