Overview
Third-party cyber risk is now an uptime problem, not just a vendor-management problem. The dangerous supplier is not always the least secure one; it is the one the business cannot operate without and cannot substitute fast enough.1,2,3 For Level 3 organizations, the practical response is a six-part operating model: map the service chain, score substitutability, design graceful degradation, plan by outage horizon, contract for operability, and treat cyber insurance as a financial backstop rather than a continuity control.4,5,3,6
Scope statement: This is a selective operationalization playbook for the handful of third parties that can materially interrupt critical services. It is not a call to expand generic third-party risk management across the full supplier estate.
