Mandating Zero Trust Architecture as a Condition of Cybersecurity Coverage
Joe Jambor
Abstract
The Change Healthcare breach in February 2024 exposed the protected health information of 190 million individuals and cost UnitedHealth Group nearly $3 billion. The breach occurred because two-factor authentication was turned off on a single portal, but was ultimately destructive because once the intruder was inside the system, there was little that could be done to stop them. This Article argues that cybersecurity insurers are uniquely positioned to prevent breaches like this one by driving adoption of Zero Trust Architecture (ZTA), the “never trust, always verify” framework codified in NIST Special Publication 800-207, by requiring its implementation as a condition of coverage. Despite its proven success rate, full ZTA adoption remains critically low, with only ten percent of large enterprises projected to reach a mature Zero Trust posture by the end of this year, as cost, institutional resistance, and legacy technology continue to impede progress. Market incentives alone have failed to move the needle. Drawing on four intersecting bodies of law; the contractual doctrine of conditions precedent in insurance agreements, federal sectoral cybersecurity regulatory frameworks including the FTC Safeguards Rule and HIPAA’s Security Rule, the state insurance regulatory architecture under the McCarran-Ferguson Act, and the rapidly evolving common law standard of reasonable cybersecurity, this Article establishes that insurer-mandated ZTA requirements are legally permissible, practically achievable through a phased implementation framework tailored to enterprises of all sizes, and essential to stabilizing the cyber insurance market while reducing legal liability for insureds.
