Vendor Security Reviews That Focus on Real Risk

Build a proportionate third-party review process around data access, service criticality, evidence quality, and ongoing change.

Tier Vendors by Exposure

Assess sensitive data, privileged connectivity, operational dependency, and substitutability. Review depth should follow exposure rather than contract value alone.

Ask for Decision-Useful Evidence

Request current assurance reports, architecture context, material exceptions, and remediation status. Questionnaires are weaker when answers cannot be verified.

Monitor Material Change

Track new integrations, ownership changes, incidents, and expiring evidence. Vendor risk changes after onboarding and needs a proportionate review cycle.

Next Steps

Use this guidance as a starting point, assign clear ownership, and validate the approach against your organization’s systems, risks, and operating constraints.
