What you will be able to do

  • Match the depth of a vendor security review to the sensitivity of the data the vendor touches.
  • Collect the minimum evidence needed to judge a vendor's security posture, such as a current audit report.
  • Confirm contractual commitments for breach notification and data deletion before signing.
  • Maintain a vendor inventory with risk ratings and review dates.

Right-size the review

Match effort to exposure. A vendor holding customer records deserves more scrutiny than a scheduling tool that stores nothing sensitive.

Key takeaways

  • Review effort should be proportionate to exposure — a vendor holding customer records deserves more scrutiny than one that stores nothing sensitive.
  • A current security summary, audit report, or trust page is a practical substitute for a lengthy custom questionnaire.
  • Breach notification and data deletion terms should be confirmed in the contract, not assumed.
  • Every reviewed vendor should be added to an inventory with an assigned risk rating and a renewal date.
