Third-party cyber risk: what employees need to do before a supplier changes

The risk changes when a vendor’s systems, services or data access change.

THE SHORT ANSWER

Third-party cyber risk awareness should help employees recognise when a supplier engagement changes in scope, geography, access, subcontracting or data handling—and trigger the approved reassessment process.

Make the trigger recognisable

A supplier already approved for one service may request new system access, a different processing location or a new dataset. Employees can mistakenly assume the earlier approval covers the change.

Translate third-party risk management requirements into a short list of change triggers. Provide the approved intake route, applicability check or risk review process rather than asking a business employee to assess technical vendor security alone.

Connect procurement, security and business ownership

The business owner needs to recognise change; procurement and third-party risk teams need enough information to assess it; information security and privacy teams may need to review access and data protections.

Rehearse a scenario where a vendor requests confidential reports in a new country or a new AI integration. The right response is to pause the scope change and obtain the required approvals.

Measure timely reassessment

Track whether scope changes are detected before implementation, whether supplier owners know the route and whether incidents involving third parties reach the correct response teams.

Vendor risk is not solved by the contract alone. It requires ongoing ownership and ordinary employee decisions throughout the engagement.

PUT IT INTO PRACTICE

Four actions to take away

  • Define scope-change triggers
  • Provide one clear review route
  • Include AI tools and data location changes
  • Check adoption after onboarding
