Third-party risk becomes material through dependencies the enterprise does not control

Govern the dependency, not only the vendor

Third-party risk arises when an external organization supports an outcome the enterprise remains accountable for. Contracts may transfer work, but not customer, regulatory or continuity consequence. Exposure depends on criticality, substitutability, access and concentration�not vendor spend alone.

The inventory should connect providers to business services, data, locations, fourth parties and recovery requirements. Ownership and platform dependencies reveal when several vendors share one failure point. Criticality is validated with process owners rather than assigned centrally from broad categories.

Due diligence follows risk: financial strength, security, resilience, conduct, capacity and legal obligations. Evidence must match the actual service and geography. Contract rights cover performance, incidents, audit, data, continuity, subcontracting and exit, but rights without operational alternatives offer limited protection.

Ongoing monitoring combines service data, control evidence, market signals and changes in scope. Thresholds trigger remediation, capacity protection or exit. Joint exercises test communication, recovery and decision authority before disruption.

The enterprise should maintain tested transition options for critical relationships, including data portability and knowledge transfer. Governance succeeds when external capability is used deliberately, residual dependence is explicit and failure can be contained without surrendering the customer promise.
