TL;DR: Supplier weaknesses became high-leverage attack paths in the 2024 cyber threat landscape, Black Kite found, with the Cleo File Transfer case showing how one flaw can ripple across many organisations. Shared dependencies now need continuous access review, revocation and monitoring, not just contract checks.
Editorial analysis by NHI Mgmt Group, based on content published by Black Kite: “Lessons Learned from the 2024 Cyber Threat Landscape”.
Key questions
Q: Why do supplier vulnerabilities create such large blast radii?
A: Because many organisations inherit the same external dependency at once.
Q: What are the signs that third-party risk management is not working well enough?
A: A weak program usually shows up as duplicate manual reviews, slow follow-up on vendor issues, and mismatches between questionnaire answers and external risk signals.
Q: What breaks when third-party access is not reviewed continuously?
A: The break is that access stays active long after the business relationship, vendor task, or application purpose has changed.
Practitioner guidance
- Tighten third-party access scope Limit external accounts, integrations, and support channels to the minimum access needed for the exact service relationship.
- Build a supplier offboarding path Ensure every vendor credential, token, API connection, and support permission can be revoked quickly when the relationship changes.
- Monitor shared supplier dependencies Track which business services depend on the same third-party platforms so one compromise cannot surprise multiple teams.
Bottom line: Third-party vendors and shared supply chain services now act as high-leverage attack paths, so governance has to cover access, revocation, and monitoring as well as contracts.

Third-party access is now an identity governance problem, not just a procurement problem. The article is clear that supplier networks and connected vendors are where modern attack paths concentrate. That means IAM and PAM teams have to care about offboarding, scoped access, and continuous review for external identities, not only internal users. Treat third-party risk management as a living access-control discipline, not a contract checklist.
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 respond when a supplier incident is disclosed?
A: Contain the reachable access first, not just the compromised account. Disable or restrict the supplier tokens, service accounts and integrations that can reach critical systems, then verify whether the same trust path exists elsewhere in the environment. The response goal is to stop propagation before the compromise spreads through connected workflows.
