Complete a vendor risk assessment questionnaire online — Any format, any framework
Need to complete a vendor risk assessment questionnaire online? Auto-fill answers from your SOC 2 and policies. Works with custom vendor assessments, third-party risk forms, and supplier evaluations.

Every enterprise buyer has one. A vendor risk assessment questionnaire — sometimes called a third-party risk assessment, supplier evaluation, or vendor security review. Whatever they call it, it's standing between you and a signed contract.
The format varies wildly. One buyer sends a 50-question Word doc. Another sends a 200-question Excel with 12 tabs. A third uses an OneTrust portal with dropdown fields. But the underlying questions are 70% the same.
Here's how to complete any vendor risk assessment questionnaire online — regardless of format or framework.
What is a vendor risk assessment questionnaire?
It's a security and compliance evaluation that companies send to their vendors before purchasing. The goal: verify that you won't become a security liability.
Every company's version is different, but they all cover the same core areas:
| Area | % of questions | What they want to know |
|---|---|---|
| Security controls | 25–35% | Encryption, access control, monitoring, patching |
| Compliance & certifications | 15–20% | SOC 2, ISO 27001, GDPR, HIPAA, industry-specific |
| Data handling | 15–20% | Where data is stored, retention, deletion, classification |
| Incident response | 10–15% | Detection, notification timelines, forensics capability |
| Business continuity | 8–12% | DR plan, RTO/RPO, backup strategy |
| Third-party risk | 5–10% | Your own vendor management, sub-processors |
| HR & physical | 5–10% | Background checks, training, facility security |
If you've completed any DDQ, SIG, CAIQ, or VSAQ before, you've answered most of these questions already. The problem is that the answers are trapped in past questionnaire responses, and every new buyer asks them in a slightly different way.
How to complete any vendor risk assessment online
1. Upload your documents once (10 minutes)
Go to FillBase and upload:
- SOC 2 Type II report — Your single most valuable document. Covers security controls, access control, incident response, and monitoring.
- 3–5 security policies — Information Security, Data Retention, Incident Response, Access Control, Business Continuity. These fill gaps the SOC 2 doesn't cover in detail.
- Past completed questionnaires — These are critical. They contain practical, detailed answers written in the format buyers expect. Upload 2–3 past DDQs or vendor assessments.
This is a one-time setup. Every future vendor risk assessment draws from the same knowledge base.
2. Submit the questionnaire (1 minute)
Upload whatever format the buyer sent — Excel, Word, PDF, or exported CSV from a portal. FillBase handles:
- Multi-tab Excel workbooks with different section structures
- Word documents with tables, nested lists, or free-form questions
- PDF forms with fillable fields
- Custom layouts with merged cells, conditional sections, and multi-part questions
3. Get AI-generated, source-cited answers (automatic)
For each question, the AI:
- Searches your knowledge base for relevant information
- Constructs an answer that addresses the specific phrasing of the question
- Cites the source document and section
- Assigns a confidence score
The AI doesn't regurgitate template answers — it reads the question, finds the relevant facts in your documents, and composes an answer that addresses what was asked. "Describe your encryption at rest approach, including algorithms and key management" gets a different answer than "Do you encrypt data at rest? Y/N."
4. Review flagged items (10–20 minutes)
Focus on:
- Low-confidence answers — Questions your documents don't cover. Answer these once and they're stored for future assessments.
- Company-specific details — SLA numbers, specific vendor names, insurance coverage amounts.
- Conditional questions — "If you answered Yes to Q12, describe..." — these sometimes need context the AI flags.
5. Export and submit (1 minute)
Get the completed assessment back in the original format. No copy-pasting between tools.
The compounding effect
Here's what most vendors miss: every vendor risk assessment you complete makes the next one faster.
- Assessment #1: 70–80% auto-filled. 15–20 minutes of review.
- Assessment #3: 80–85% auto-filled. 10–15 minutes of review.
- Assessment #5: 85–92% auto-filled. 8–12 minutes of review.
- Assessment #10: 90–95% auto-filled. 5–10 minutes of review.
This happens because your knowledge base grows with every correction and manual answer. The 50 most common security questions get locked in after 2–3 assessments. Industry-specific questions fill in over the next few.
Handling different buyer platforms
Buyers use different platforms to send vendor risk assessments. Here's how FillBase fits into each workflow:
| Platform | Workflow |
|---|---|
| Email (Excel/Word/PDF) | Upload directly to FillBase, complete, export, reply |
| OneTrust | Export questionnaire as Excel → complete in FillBase → import answers back |
| ProcessUnity | Export as CSV/Excel → complete → import |
| Whistic | Export → complete → import (or share your Whistic profile + completed responses) |
| ServiceNow VRM | Export → complete → import |
| Custom portal | Most portals offer export. If not, screenshot/copy questions into a spreadsheet |
Direct portal integrations are on our roadmap. For now, the export/import workflow adds ~5 minutes.
Vendor risk assessments are accelerating
Third-party risk management is getting stricter:
- SOC 2 requirement spreading — More mid-market buyers (not just enterprise) now require vendor security assessments
- Continuous monitoring — Annual assessments are shifting to quarterly or real-time
- Regulatory pressure — DORA, NIS2, SEC cyber rules are forcing companies to assess all vendors
- AI-specific assessments — New questions about AI model training, data usage, and bias are appearing in 2026 assessments
If you're a SaaS vendor, the volume of vendor risk assessments you receive will only increase. Building a strong knowledge base now saves exponentially more time later.
Frequently asked questions
Can I complete a vendor risk assessment online for free? Yes. FillBase's free tier includes 200 requirements per month — enough for 1–2 typical vendor assessments.
What if the assessment has industry-specific questions (HIPAA, PCI-DSS, etc.)? Upload your industry-specific compliance documentation. For HIPAA: your BAA template and HIPAA security policies. For PCI: your SAQ or AOC. The AI uses whatever you provide.
How does FillBase handle "evidence upload" requests? FillBase completes the questionnaire answers. When the buyer asks for supporting documents (SOC 2 report, certificates, policies), you attach those separately. FillBase can tell you which documents to include based on the questions asked.
My buyer uses a portal and doesn't allow export. What do I do? Copy the questions into a spreadsheet (most portals let you at least view them), complete in FillBase, then paste answers back. It's not ideal — direct integrations are coming — but it still saves significant time vs. answering each question manually.
Can multiple team members contribute? Yes. FillBase works through Slack — when the AI encounters a question it can't answer (e.g., HR policy details), it pings the appropriate person for input. Their answer gets added to the knowledge base automatically.
Complete your next vendor assessment in minutes
You shouldn't spend 8 hours answering the same security questions you answered last month for a different buyer. Sign up for FillBase, upload your SOC 2, and complete your next vendor risk assessment online in a single sitting.
