TL;DR: Third-party access governance weakens when vendor identities get broad network reach and persistent credentials, Securden notes. Vendor access needs tighter scoping, visibility, and offboarding to keep entitlement tied to the work, not just the connection.
Editorial analysis by NHI Mgmt Group, based on content published by Securden: “Best Practices for Securing Third-Party Access to Corporate Networks”.
Key questions
Q: Why do long-lived vendor credentials increase security risk?
A: Long-lived vendor credentials extend the time an attacker can exploit a stolen or abandoned account.
Q: What do security teams get wrong about third-party access oversight?
A: They often track vendor access as a procurement issue instead of a lifecycle control.
Q: What breaks when third-party access is handled like ordinary VPN access?
A: The control model breaks because a VPN only proves connectivity, not entitlement to privileged actions.
Practitioner guidance
- Define named third-party identities Replace shared vendor accounts with named, role-specific identities so every session can be tied to a person and a contract scope.
- Set access expiry to contract reality Link permissions to project end dates, procurement records, or service agreements so vendor access expires when the work does.
- Require phishing-resistant MFA for all vendors Use strong MFA methods for every external account, with certificate-based or key-based authentication for privileged sessions.
Bottom line: Third-party access becomes a governance issue when external identities inherit broad network reach and persistent credentials.

Third-party access is an identity lifecycle problem, not a network convenience problem. External users need access because business operations require it, but that access must be governed as a named identity with a clear start, scope, and end. When organisations treat vendor connectivity as an exception path, they create persistent trust that outlives the work. The practitioner implication is to manage third-party access with the same lifecycle discipline used for any other high-risk identity population.
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: How should organisations compare secure brokering with traditional VPN access for vendors?
A: Traditional VPN access gives broad network trust, while secure brokering mediates access to specific systems and keeps the session visible. The difference matters because third-party governance depends on limiting reach and preserving accountability, not just getting a remote user connected. For vendor access, brokering is the tighter control model.
