TL;DR: Third party risk management programs fail when organisations treat vendor oversight as a one-time review instead of a lifecycle discipline spanning onboarding, monitoring, and offboarding, according to SecurEnds. The real governance gap is not visibility alone but whether access, accountability, and review processes stay aligned as vendor relationships change.

Editorial analysis by NHI Mgmt Group, based on content published by SecurEnds: “How to Start a Third Party Risk Management Program”.

Key questions

Q: What breaks when vendor risk management is only a point-in-time review?

A: The programme loses track of access, accountability, and control drift after onboarding.

Q: When should organisations re-evaluate third party risk rather than rely on annual reviews?

A: They should re-evaluate whenever the vendor relationship changes in a material way, such as access scope, service dependency, contract status, or compliance posture.

Q: How do organisations know their external risk management program is actually working?

A: A working program shows that internet-facing assets are discovered quickly, assigned to owners, and remediated before they become easy targets.

Practitioner guidance

  • Define vendor lifecycle stages Map onboarding, active use, review, renewal, and offboarding into one governed workflow so every vendor has a clear state and owner.
  • Build a centralized vendor inventory Maintain one source of truth for vendor access, data handling, service criticality, and business owner so risk tiers can be assigned consistently.
  • Separate assessment from approval Require a documented review outcome before access is granted, but also require ongoing review triggers when the vendor relationship changes.

Bottom line: Third party risk management fails when governance stops at approval and never follows the vendor through its full lifecycle.

Vendor lifecycle control is the real unit of third party risk governance. A vendor risk programme fails when it treats onboarding as the main event and monitoring as a support function. The article correctly shifts attention to the full relationship arc, where risk changes with access scope, service dependency, and contract status. That means governance must follow the relationship from approval through disengagement, or the control model will always lag reality.

A few things that frame the scale:

  • 92% of organisations expose NHIs to third parties, raising concerns about supply chain security, according to the Ultimate Guide to NHIs.

A question worth separating out:

Q: Who should own vendor lifecycle governance across security and procurement?

A: Ownership has to be shared, but accountability cannot be vague. Security should govern risk evaluation, procurement should manage commercial terms, and legal should define obligations, while a named business owner remains responsible for the vendor’s ongoing need and access. Without explicit ownership, vendor governance becomes fragmented and unenforceable.
