TL;DR: Third-party cyber risk management now sits at the intersection of vendor access, identity governance, and continuous monitoring, because vendor, SaaS, cloud, and IT partner connections extend the attack surface and create legitimate access paths for abuse, according to SecurEnds. Periodic assessments are no longer enough; governance has to follow access, dependencies, and offboarding across the full vendor lifecycle.
NHIMG editorial — based on content published by SecurEnds: third-party cyber risk management and vendor access governance
Questions worth separating out
Q: How should security teams manage third-party cyber risk in practice?
A: Security teams should treat third-party cyber risk as a continuous identity and access problem.
Q: Why do vendor integrations increase enterprise security risk?
A: Vendor integrations increase risk because they create legitimate access paths into internal systems, often across multiple applications and data stores.
Q: What breaks when third-party offboarding is weak?
A: When offboarding is weak, vendor credentials, integrations, and support access can remain active long after the business relationship ends.
Practitioner guidance
- Inventory every external identity and integration Build a complete list of vendor accounts, API keys, support roles, and SaaS connections, then assign each one an owner, purpose, and revocation path.
- Tie access reviews to active third-party entitlements Review not just the vendor relationship but the live permissions, token scope, and remote access paths that relationship still enables.
- Automate monitoring for posture drift and exposed credentials Track changes in vendor security posture, integration settings, and credential exposure continuously rather than waiting for the next questionnaire cycle.

SecurEnds' full guide covers the operational detail this post intentionally leaves for the source:
- Vendor risk scoring workflow that maps access, data sensitivity, and business criticality into a prioritisation model.
- Continuous monitoring methods for vendor posture, security ratings, and threat signals across connected ecosystems.
- Offboarding steps for revoking access, removing integrations, and verifying that data handling has ended.
- Automation use cases for questionnaire handling, evidence collection, and anomaly alerting in larger vendor programmes.

Third-party cyber risk is an identity governance problem before it is a vendor management problem. The article correctly treats external access as a security issue, but the control boundary is identity, not procurement. Once a vendor account, integration token, or support channel exists, it must be governed like any other privileged non-human identity. The practitioner conclusion is that vendor security posture only matters if access lifecycle control exists on the buyer side.
A few things that frame the scale:
- 91.6% of secrets remain valid five days after the targeted organisation is notified, showing a critical gap in remediation procedures, according to Ultimate Guide to NHIs.
- Only 20% of organisations have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them, according to Ultimate Guide to NHIs.
A question worth separating out:
Q: Who is accountable when a vendor causes a cyber incident?
A: Accountability sits with both sides, but the buying organisation remains responsible for governing the access it granted. Security, IAM, procurement, and the business owner all need clear ownership for onboarding, monitoring, and revocation. If no one owns the full lifecycle, third-party risk becomes an inherited control gap.
