TL;DR: Third-party cyber risk has shifted into vendor governance, Jscrambler reports, because external access expands the attack surface across the full vendor lifecycle. Vendor access needs monitoring, revocation, and compliance evidence tied together to avoid lifecycle drift.
Editorial analysis by NHI Mgmt Group, based on content published by Jscrambler: “Starting Letter: V”.
Key questions
Q: Why does third-party access create more segmentation risk than internal access?
A: Third-party access often combines external connectivity, broad task scope, and weaker visibility into the requester’s environment.
Q: What breaks when vendor offboarding is not verified?
A: Orphaned access survives.
Q: How should security teams govern vendor access across the third-party lifecycle?
A: Security teams should govern vendor access as a lifecycle, not a one-time approval.
Practitioner guidance
- Define vendor access as a lifecycle-controlled entitlement Record every third-party account, integration, and remote access path in the same inventory used for internal identities so approvals and revocations are visible.
- Tie offboarding to access removal Make vendor contract termination trigger account disablement, token revocation, and data access closure before the relationship is considered complete.
- Reassess third-party access on a fixed cadence Review whether each vendor still needs its current level of access, especially where the vendor handles sensitive data or production support.
Bottom line: Third-party cyber risk is a governance issue because vendor access expands the organisation's effective attack surface.

Third-party cyber risk is a lifecycle control problem, not a supplier questionnaire problem. The article is right to tie risk to selection, monitoring, remediation, and offboarding rather than to a single due diligence moment. Once a vendor can touch systems or data, the merchant is governing an access relationship as much as a commercial relationship, which changes the control model. Practitioners should manage vendors as continuously governed access holders, not one-time approved partners.
A question worth separating out:
Q: What should organisations check before a vendor touches payment data?
A: Organisations should confirm whether the vendor's access, monitoring, and incident obligations align with PCI DSS expectations for a secure cardholder-data environment. They should also verify that the merchant can prove who had access, when access changed, and how access was revoked or limited if risk increased.
