TL;DR: Third-party and fourth-party access often becomes a blind spot because organisations cannot consistently see what vendors touch, when they touch it, or whether their own controls extend downstream, according to Imprivata. The governance gap is not remote access itself, but the lack of lifecycle control, auditability, and minimum necessary access across the vendor chain.
Editorial analysis by NHI Mgmt Group, based on content published by Imprivata: “Best practices: Eight great ways to help mitigate vendor access risks”.
Key questions
Q: What breaks when third-party remote access is not tightly scoped?
A: When vendor access is not tied to a specific purpose and expiry, organisations lose control over who can reach sensitive systems, what they can touch, and how long the access remains valid.
Q: Why do fourth-party relationships increase remote access risk?
A: Fourth-party relationships add another actor whose access may be invisible to the organisation even though it can still affect production systems and sensitive data.
Q: What are the signs that vendor access governance is failing?
A: Common signals include long-lived support privileges, unclear ownership of vendor accounts, inconsistent offboarding, and access paths that reach multiple systems without segmentation.
Practitioner guidance
- Map the vendor access chain Inventory direct third-party access and any pass-through fourth-party reach, then tie each relationship to a named business purpose, data set, and owner.
- Replace broad remote access with task-scoped sessions Grant access only for the approved support task, keep the permissions minimum necessary, and set an explicit expiry that matches the work order.
- Enforce contractual pass-through obligations Require vendors to impose your security requirements on their own suppliers, including audit rights, liability terms, and evidence of downstream controls.
Bottom line: Third-party remote access becomes a fourth-party governance issue when organisations cannot see, constrain, and evidence downstream use of external access.

Third-party remote access becomes a fourth-party governance problem the moment access is delegated without end-to-end accountability. The article is right to push beyond the vendor boundary, because pass-through obligations and subcontracted support create identity risk that conventional third-party reviews often miss. The relevant governance question is not whether a vendor is trusted in principle, but whether the organisation can prove who actually exercised access across the chain. Practitioners should treat indirect access as a governed identity relationship, not a technical exception.
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.
- 43% of security professionals are concerned about AI systems learning and reproducing sensitive information patterns from codebases, according to the State of Secrets in AppSec.
A question worth separating out:
Q: How should security teams handle third-party NHI access offboarding?
A: Treat third-party NHI access as a lifecycle event with an owner, expiry condition, and revocation test. If the business relationship changes, the credential should not remain valid by default. The offboarding process must remove access from OAuth apps, service accounts, and integration tokens together.
