TL;DR: Third-party security rises or falls on how well organisations control external access, monitor vendor behaviour, and enforce contract-backed security requirements, according to Zluri's analysis of vendor, operational, compliance, reputational, financial, and strategic risk. The real issue is not vendor count, but whether access, oversight, and offboarding are governed as one lifecycle.
Editorial analysis by NHI Mgmt Group, based on content published by Zluri: “6 Strategies To Improve Third-Party Security”.
Key questions
Q: What breaks when third-party access is not governed as part of identity lifecycle management?
A: Access can outlive the business relationship that justified it, which leaves external identities active after need has ended.
Q: Why do third-party vendors create such high compliance and security risk for organisations?
A: Because a vendor failure can still become your failure in the eyes of regulators, customers, and auditors.
Q: What do IAM teams get wrong about third-party risk management?
A: They focus on vendor approval as a one-time event instead of governing the full lifecycle of access.
Practitioner guidance
- Define third-party identity classes Separate vendors, contractors, and partners by the systems, data, and administrative functions they can reach, then assign explicit owners for each class.
- Tie contracts to access controls Require security clauses that map to concrete controls such as encryption, audit rights, incident reporting, and revocation obligations.
- Review access at renewal and termination Treat renewal, suspension, and termination as mandatory access review events so external accounts do not persist past the business relationship.
Bottom line: Third-party security is fundamentally an access governance problem because external parties create risk through the permissions they hold and the oversight they receive.

Third-party security is access governance, not a side issue in vendor management. Once an external party can touch data or systems, the risk is governed by identity, entitlement, and revocation discipline. That makes vendor security part of IAM architecture, not merely procurement oversight. Practitioners should stop treating third parties as a separate category and govern them as externally held identities.
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: What should security teams do when a vendor relationship ends?
A: They should confirm that access has been revoked, integrations are disabled, data has been returned or deleted, and any downstream dependencies are removed before closure. Offboarding is a lifecycle control, so the relationship is not complete until the identity and access footprint is fully withdrawn.
