Reduce exposure introduced by suppliers, partners, and outsourced services by assessing risk, setting requirements, monitoring changes, and managing security incidents across the supply chain.

Many critical services depend on third parties (SaaS, managed services, software suppliers). This use case ensures the business understands and manages that dependency risk.

Outcomes

  • Reduced risk from vendor breaches and insecure integrations
  • Clear security requirements in procurement and contracts
  • Faster impact assessment when a supplier issue emerges
  • Better continuity planning for critical third-party dependencies

Typical scope

  • Security due diligence and onboarding requirements
  • Continuous monitoring of supplier risk signals and material changes
  • Contractual controls (e.g., breach notification, audit rights)
  • Third-party incident coordination and reporting
