TL;DR: Third-party risk management now sits at the intersection of cybersecurity, compliance, and identity governance as vendor access to cloud, SaaS, and outsourced services expands the enterprise attack surface, according to SecurEnds. The security issue is not vendor presence itself, but unmanaged permissions and weak lifecycle controls that let third parties outlive their legitimate access window.

Editorial analysis by NHI Mgmt Group, based on content published by SecurEnds: “Third Party Risk Management (TPRM) – Complete Guide & Software Overview”.

Key questions

Q: What breaks when third-party access is not offboarded cleanly?

A: The organisation loses control of who can still reach sensitive systems after the business need has changed.

Q: Why do third-party identities create so much risk in industrial environments?

A: Third-party identities create risk because they often bridge operational systems, shared workstations, and external support platforms with broader privileges than internal users would receive.

Q: How can IAM teams tell whether vendor access is too broad?

A: Vendor access is too broad when the identity can reach systems or data outside the task it was hired to perform, especially if the permissions are permanent or reused across multiple services.

Practitioner guidance

  • Build a complete vendor identity inventory Record every external account, integration, token and contractor identity with owner, system scope and business purpose.
  • Tie access approval to explicit lifecycle checkpoints Require onboarding, recertification and offboarding events for every third-party identity so access cannot persist after the business need ends.
  • Enforce task-scoped least privilege for vendors Limit third-party permissions to the minimum functions and data sets needed for a specific contract, project or support obligation.

Bottom line: Third-party risk management now functions as identity governance because external vendors, contractors and SaaS providers are granted access paths that must be owned, scoped and removed.

Third-party risk management is now a form of identity governance, not a separate control domain. The article describes vendors, contractors and SaaS providers as actors that receive access, permissions and lifecycle treatment inside the enterprise. That means the decisive question is who can do what, for how long, and under whose ownership. Security teams that still treat TPRM as procurement due diligence will keep missing the access layer that actually creates exposure. The practitioner conclusion is simple: vendor risk becomes governable only when it is managed as identity.

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 organisations do when vendors connect through SaaS and APIs?

A: They should govern those connections as identities, not as simple integrations. That means assigning an owner, scoping the permissions, reviewing the access on a schedule, and removing the account or token when the business relationship ends. Otherwise the integration becomes a durable access path rather than a controlled dependency.
