+# Private AI lab access restrictions create offense-defense imbalances in government cyber capability through unilateral deployment decisions without accountability structures
+
+Anthropic's decision to restrict Mythos access due to its 'unprecedented ability to quickly discover and exploit security vulnerabilities' created a concrete governance gap: NSA (offensive cyber) received access while CISA (civilian defensive cyber) did not. This is not merely a commercial decision—it's a cyber governance decision made without any accountability structure. CISA's mission is precisely the civilian infrastructure defense that Mythos threatens, yet the agency was excluded from the 40+ organization restricted testing cohort. The pattern reveals a governance vacuum: there is no mechanism ensuring that defensive operators get access commensurate with the threat that offensive capabilities create. Private labs' unilateral access restriction decisions are making strategic cyber governance choices—who gets which capabilities, when—without any policy framework or oversight. This is distinct from voluntary safety constraints (which can be overridden by customers) or legislative ceilings (which apply to statutory scope). This is information asymmetry within government created by private deployment decisions, where the lab's security calculus produces offense-defense imbalances as a side effect.

 Mythos evaluation occurred while Anthropic negotiates Pentagon deal, creating direct tension between safety evaluation findings (first model to complete end-to-end attack chains) and customer capability demands (military procurement). The timing demonstrates how voluntary safety frameworks face pressure when primary customer specifically wants the capability that safety evaluation flags as concerning.

+The CISA/NSA Mythos access asymmetry reveals a third failure mode beyond customer override: private labs' access restriction decisions create strategic capability imbalances within government. NSA (offensive) received Mythos access while CISA (defensive) did not, despite CISA's mission being precisely the civilian infrastructure defense that Mythos threatens. This is governance through omission—no mechanism exists to ensure defensive operators get access commensurate with offensive threat.
