TL;DR: Unmanaged vendor access creates a high-risk path into internal systems because third parties often need privileged remote access, and a healthcare study cited by Imprivata found 56% of organisations experienced a third-party related breach in the past year. This is a governance problem, not just an access problem: standing privilege, weak visibility, and manual approvals all widen the blast radius.
Editorial analysis by NHI Mgmt Group, based on content published by Imprivata: “What is vendor privileged access management (VPAM)?”.
By the numbers:
- Over half of organisations, 56%, experienced a third-party-related breach within the past year, according to Imprivata.
- Roughly two-thirds expect the number of data breaches to rise over the next 12 to 24 months, according to Imprivata.
Key questions
Q: What breaks when vendor access is granted without granular controls?
A: All-or-nothing access breaks the principle of least privilege and widens the blast radius of any compromise.
Q: Why do third-party breaches so often involve privileged access?
A: Third-party breaches often involve privileged access because external accounts are frequently granted broad, persistent reach to get work done quickly.
Q: How do security teams know whether vendor access is actually governed?
A: They should be able to answer three questions without delay: who has access, what they can reach, and how quickly access can be removed everywhere it exists.
Practitioner guidance
- Define vendor identities as privileged actors Place third-party users into the same governance model used for high-risk internal admins, with explicit ownership, approval paths, and offboarding obligations for every external account.
- Eliminate standing vendor privilege Grant access only for the approved task window and revoke it automatically at session end, rather than leaving accounts permanently enabled for future maintenance.
- Broker every privileged vendor session Route external access through a secure gateway and vault rather than exposing credentials directly to the vendor or allowing direct administrative logins.
Bottom line: Vendor access becomes a security issue when third parties are granted privileged reach without the same task-level controls applied to internal administrators.

Vendor access is a privileged identity governance problem, not a remote-access convenience problem. The article is describing a control boundary where external users are granted enough reach to maintain, repair, or administer internal systems. That is squarely in PAM and NHI governance territory because the risk comes from who can act, what they can reach, and for how long. The practitioner implication is that vendor identities must be governed as high-risk privileged actors, not as ordinary contractors with a login.
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:
A: After a third-party account is identified as the entry point, organisations should revoke exposed credentials, review all connected access paths, reset affected sessions, and determine whether the same trust relationship exists elsewhere. They should also validate logs, notify internal stakeholders, and tighten vendor controls before restoring normal access. The key objective is to stop lateral movement and prevent repeat exposure through the same relationship.
