What is Vendor Management?

Third-party risk management has become increasingly critical as organizations rely on dozens or hundreds of SaaS tools, cloud providers, and outsourced services. A single vendor breach can expose an organization's data regardless of its own security posture. Effective vendor management programs include several phases: pre-engagement due diligence (reviewing SOC 2 reports, security questionnaires, and penetration test results), contractual protections (data processing agreements, SLAs, breach notification requirements, right-to-audit clauses), ongoing monitoring (tracking vendor security ratings, reviewing updated compliance reports annually, and monitoring for breaches), and offboarding procedures (ensuring data return or destruction). SOC 2 auditors evaluate vendor management controls extensively because service organizations often rely on sub-service organizations. ISO 27001 addresses supplier relationships through specific Annex A controls. GDPR requires data controllers to ensure processors provide sufficient guarantees of appropriate technical and organizational measures.
