Third-Party Security Management Toolkit

Vendor security fails in most organizations not at due diligence but afterward. The questionnaire comes back, the contract is signed, and nothing happens again until a customer, auditor or incident forces it. This toolkit makes the post-signature lifecycle the center of the work.

The workbook has nine working tabs: instructions, vendor inventory, criticality assessment across six scored factors, security evidence across twelve evidence types, risk assessment using likelihood times impact, remediation with validation, exceptions with approval and expiry, a review calendar with a twelve-month forecast, and a dashboard in which nothing is typed. It works in Excel 2010 or later and in Google Sheets.

The implementation guide explains every calculation, gives a six-week rollout plan, and shows how to actually read vendor evidence: SOC 2 scope, opinions, exceptions and complementary user entity controls; ISO 27001 scope statements; penetration test letters; and what to focus on for managed IT providers, payroll and HR platforms, cloud hosting, payment processors and AI tools.

Aligned to NIST CSF 2.0 GV.SC, NIST SP 800-161 Revision 1, CIS Controls v8.1 Control 15 and ISO/IEC 27001:2022 supplier controls.
