TPRM at machine speed: why calendar-based reviews are breaking

TL;DR: Manufacturing suppliers and service providers now create a machine-speed risk surface because they connect to internal systems, host data, and keep operations running, while one manufacturer cut vendor risk assessments to less than 2 weeks, according to Safe Security. Calendar-based review cycles no longer match the speed of third-party exposure, and TPRM has to become continuous rather than periodic.

Key questions

Q: What breaks when third-party risk reviews are still run on a calendar instead of on change events?

A: Calendar-based reviews miss the moments when vendor access actually changes, such as new integrations, new credentials, or wider data reach.

Q: Why do third-party vendors complicate identity governance more than internal users?

A: Third-party vendors complicate governance because their access is often tied to contracts, projects, and temporary business needs rather than stable employment.

Q: How can security teams know whether third-party risk management is working?

A: Look for evidence that inventory, review, monitoring, and revocation are all connected.

Practitioner guidance

• Define a vendor access inventory Record every supplier and service provider with internal connectivity, the systems they touch, the credentials they use, and the business owner accountable for them.
• Replace annual reviews with event-driven reassessment Trigger reassessment when a vendor gains new systems, changes scope, requests new credentials, or crosses a higher-risk data boundary.
• Tighten offboarding for third-party identities Require revocation of tokens, API keys, service accounts, and other vendor-held credentials as a formal exit step, not an informal follow-up.

Bottom line: Third-party risk becomes materially harder to govern when suppliers can change internal exposure faster than scheduled reviews can detect it.
