Vendor Risk Management: Vetting Third Parties Before They Touch Your Data

A practical framework for vetting, contracting with, and continuously monitoring third-party vendors that touch sensitive company data.

The Weakest Link Is Rarely Internal

A growing share of major breaches originate not in the victim's own systems but through a third-party vendor with access to their data or network. Supply chain risk has become a board-level concern.

Building a Vetting Process

A structured vendor risk program scores prospective vendors on data access scope, their own security certifications, breach history, and contractual accountability before any contract is signed.

Contractual Levers

Breach notification timelines, right-to-audit clauses, and liability allocation should be negotiated as security terms, not left to standard boilerplate legal language.

Ongoing Monitoring

Vetting at onboarding is not enough — vendors should be re-assessed periodically, since their security posture (and the sensitivity of what they access) changes over time.
