# Vendor security assessment questionnaire (free template)

A security questionnaire you can send to a SaaS vendor or supplier today: numbered questions grouped by area, a short Lite version for low-risk vendors, the framework each area maps to, and a CSV with answer and evidence columns.

 [See the 75 questions](#questionnaire) [Download CSV](https://www.helprange.com/vendor-security-assessment-questionnaire.csv)

**Short answer:** a vendor security assessment questionnaire (often just "security questionnaire") is how you check a supplier before it gets your data. This template has **75 questions in 14 areas** – governance and certifications, subprocessors, people, access, encryption, development, infrastructure, vulnerability management, logging, incidents, continuity, privacy, AI and physical security. The **31 questions marked Lite** are the short version for low-risk vendors. Every area shows the NIST CSF 2.0 categories and CSA Cloud Controls Matrix domains it relates to.

The questions are our own wording. Only the topic areas follow public frameworks (sources at the bottom); nothing is copied from the licensed SIG or CAIQ questionnaires.

## How to use it

1. **Tier the vendor.** No access to personal or confidential data: send the Lite questions. Stores your customer data or runs a critical process: send the full version and ask for evidence.
2. **Ask for the SOC 2 Type II report or ISO 27001 certificate first.** If it is current and covers the product you are buying, only send the questions it does not answer (usually data location, subprocessors, breach notification time, deletion at exit and AI use).
3. **Require evidence for every Lite question** – a policy, a report page, a screenshot of a setting. The CSV has Answer, Evidence and Notes columns.
4. **Score and decide.** Yes / Partial / No / N/A, weighted by what the vendor will do for you. Record accepted risks and the review date (at least yearly for critical vendors).

** Red flags**
- No independent report or certification for a vendor that will hold your data
- SOC 2 scope that excludes the product you are buying
- MFA not enforced for staff with production access
- No commitment to a breach-notification time

## Frameworks this template is based on

| Framework | What we used |
|---|---|
| [NIST Cybersecurity Framework (CSF) 2.0](https://nvlpubs.nist.gov/nistpubs/CSWP/NIST.CSWP.29.pdf) | Published 26 February 2024. Six functions – Govern (GV), Identify (ID), Protect (PR), Detect (DE), Respond (RS), Recover (RC) – and their categories (e.g. PR.AA identity and access control, GV.SC supply-chain risk). Free and public. |
| [CSA Cloud Controls Matrix (CCM) v4.1 and CAIQ](https://cloudsecurityalliance.org/research/cloud-controls-matrix) | 197 control objectives in 17 domains (A&A, AIS, BCR, CCC, CEK, DCS, DSP, GRC, HRS, IAM, IPY, IVS, LOG, SEF, STA, TVM, UEM); the CAIQ is the yes/no questionnaire built on it. Free for internal use; commercial use needs a CSA licence, so we map to domains only. |
| [Shared Assessments SIG (Lite and Core)](https://sharedassessments.org/sig/) | The Standardized Information Gathering questionnaire, widely used in financial services. It is a licensed product: we only used its broad risk areas (governance, third parties, access, application security, incident management, resilience, privacy) as a checklist of topics – no SIG questions are reproduced. |
| [ISO/IEC 27001:2022, Annex A](https://www.iso.org/standard/27001) | 93 controls in four themes: organisational, people, physical and technological. Ask for the certificate and the Statement of Applicability rather than re-asking every control. |
| [AICPA SOC 2 – Trust Services Criteria](https://www.aicpa-cima.com/topic/audit-assurance/audit-and-assurance-greater-than-soc-2) | Security (required), availability, processing integrity, confidentiality and privacy. A recent SOC 2 Type II report answers most questions in areas 1–11; use the questionnaire for the gaps. |

FAQ

## Security questionnaires – questions

What is a vendor security assessment questionnaire?

A list of questions a company sends to a supplier before sharing data with it or relying on its service. It covers governance and certifications, subprocessors, people, access control, encryption, secure development, vulnerability management, logging, incident response, continuity, privacy and – increasingly – AI. The answers and evidence feed the vendor risk assessment.

Is a vendor risk assessment questionnaire the same thing?

Mostly. "Vendor risk assessment questionnaire" is the broader term: besides security it may cover financial health, compliance, ESG and operations. This template is the security part; for company, financial and contract checks use the vendor due diligence checklist and combine the two.

Should I use the Lite or the full version?

Tier your vendors first. Low-risk vendors with no access to personal or confidential data: the Lite questions are enough. Vendors that store customer data or run a critical process: the full version plus evidence (SOC 2 report, ISO 27001 certificate, penetration test summary).

Do I need a questionnaire if the vendor has a SOC 2 report?

Ask for the report first. A current SOC 2 Type II report with no relevant exceptions answers most of areas 1–11, so send only the questions it does not cover – typically data location, subprocessors, breach notification time, deletion at exit and AI use. Check that the report's scope matches the product you are buying and read the complementary user entity controls.

How is this different from SIG or CAIQ?

SIG (Shared Assessments) and CAIQ (Cloud Security Alliance) are standard questionnaires with hundreds of questions; SIG is licensed and CAIQ needs a licence for commercial use. This template is shorter, written in plain English and free to use – each area lists the NIST CSF 2.0 categories and CCM domains it relates to, so you can line answers up with a vendor's completed CAIQ or SIG.

How should answers be scored?

Use Yes / Partial / No / Not applicable, require evidence for every Lite question, and weight areas by what the vendor will do for you – a payroll provider's data protection answers matter more than its physical security. A "No" on MFA, encryption, breach notification or deletion at exit is usually a blocker for vendors that hold personal data.

Can I use and edit this template?

Yes – copy it, edit it and send it to your vendors. It is a practical starting point, not legal or audit advice; adapt it to your regulator's expectations (for example DORA or NIS2 for EU financial and essential entities).
