Vendor Security Assessment Pack — 50-Question NIST-Mapped Questionnaire (Excel + Guide)

Assess any vendor's security in one sitting — without building the questionnaire yourself.

The Vendor Security Assessment Pack gives you a complete, ready-to-send third-party security questionnaire: 50 questions across 10 sections, covering governance, access control, data protection, network security, logging & monitoring, incident response, business continuity, physical security, personnel security, and compliance & audit.

Every question is mapped to the frameworks your auditors and customers actually use:

• NIST SP 800-53 Rev. 5
• ISO/IEC 27001:2022 Annex A
• SOC 2 Trust Services Criteria
• PCI DSS v4.0.1 (only where the requirement genuinely applies)
• NIST CSF 2.0

It scores itself. Vendors answer Yes / Partial / No / N/A. Critical questions carry double weight, N/A answers are excluded fairly, and the Score Summary tab produces a weighted score, a suggested risk tier (Low / Medium / High / Critical), and a per-section breakdown that shows exactly where a vendor is weakest.

Reviewer guidance is built in. Each question includes a "What good looks like" note — the specific evidence a strong answer should produce — so reviews stay consistent no matter who runs them.

What's inside

• Vendor_Security_Assessment_Workbook.xlsx — instructions, the full 50-question assessment with response dropdowns and automatic scoring, and the Score Summary dashboard.
• Vendor_Security_Assessment_Guide.docx — a step-by-step administrator guide: how to run an assessment, how scoring and tiers work, and reviewer tips.

Who it's for: companies onboarding SaaS, cloud, or IT vendors that need a defensible security review; security & compliance leads building a third-party risk management (TPRM) process; consultants who need a client-ready questionnaire today, not next month.

License: single-organization license — use the pack for your own vendor assessments, unlimited times. Templates support your security program; they are not legal or audit advice and do not guarantee any audit outcome.
