AI Vendor Security Questionnaire: 25 Questions Owner-Operators Should Send

Last Updated: June 2026

An AI vendor security questionnaire is a written list of questions. You send it before you sign. It checks how the vendor stores your data. The IBM Cost of a Data Breach Report (2024) found the average breach hit $4.88 million in 2024.

AI Smart Ventures has helped growing firms with AI Adoption and vendor checks since 2015. Most owners think big AI tools are safe. That is not always true.

Key Takeaways

• Breach Cost Baseline – The average breach hit $4.88 million in 2024, per the IBM Cost of a Data Breach Report (2024). A vendor review is the cheapest way to cut that risk.
• Best Time to Ask – Send security questions before you sign. After signing, most vendors will not add deletion clauses or breach timelines.
• Data Processing Agreement – Any vendor that handles personal data under GDPR or CCPA must give you a signed Data Processing Agreement (DPA). Without one, your firm bears the legal risk. Request this before you sign anything.
• Review Time – A clear questionnaire takes under two hours to send. Vendors who cannot reply in 10 business days likely have no formal security records.
• SOC 2 Type II Baseline – SOC 2 Type II from the AICPA means an outside firm checked the vendor’s controls over 12 months. Vendors who refuse to share it under NDA should be cut from your shortlist.

Vendor security is a contract choice. You do not need a security team. You need a list. And you need the will to walk away when a vendor cannot answer.

Why Do Owner-Operators Need to Vet AI Vendors?

Owner-operators sign AI deals fast. Most do not read the data terms. The Verizon 2024 Data Breach Investigations Report found outside vendors caused 15% of all breaches in 2023. That number is up 68% from the year before.

Owner-run firms get hit the hardest. They often have no IT staff and no breach plan. Getting answers in writing before you sign puts you in control.

What Data Questions Should You Send a Vendor?

Data questions cover where your files live and who can see them. Send all eight in writing. Keep each reply on file. A verbal promise has no legal weight.

• Data Storage Location – Where is my data stored? Which country or cloud region?
• Data Access Controls – Which staff can see my data, and when?
• Training Data Use – Is my data used to train your AI models? Can I opt out?
• Data Retention Period – How long do you keep my data after I cancel?
• Data Deletion Rights – Can I request full deletion at any time, with written proof?
• Sub-processors – Do you share my data with outside partners held to the same rules?
• Data Portability – Can I export all my data before I cancel? How quickly?
• Encryption – Is my data locked at rest and in transit using AES-256 or equal?

A vendor who cannot answer all eight in writing has no data policy. That is a sign to look at a different tool.

Which Compliance Questions Protect Your Business?

Compliance questions check if the vendor meets legal rules for your field. For any vendor that touches EU or California data, get a signed DPA first. Do this before you create an account. Without one, your firm may take full blame if the vendor causes a breach.

• DPA Availability – Do you offer a standard DPA? Can I sign it before I start?
• GDPR Status – Are you a registered data processor under GDPR? Who is your EU contact?
• CCPA Compliance – Does your work follow CCPA? How do you handle deletion requests from California users?
• HIPAA Readiness – If I handle health data, do you sign a Business Associate Agreement (BAA)?
• SOC 2 Type II Report – Do you have a current SOC 2 Type II report? Will you share it under NDA?
• Pen Testing – Do you run outside security tests? How often? Will you share a summary?
• Regulation Updates – How do you update your legal stance when laws change?

What Incident Response Questions Should You Ask?

Incident response questions tell you what the vendor will do when a breach occurs. Most owners skip this section. A vendor with no breach timeline leaves you on your own. You will have to manage all customer messages yourself.

GDPR sets a 72-hour notice rule. Ask vendors how fast they move. Ask each vendor for a one-page breach plan before you sign.

• Breach Timeline – How fast do you tell me if my data is in a breach?
• Notice Method – Will you contact me by email, phone, or dashboard?
• Security Contact – Who is my named security contact? Is there a dedicated team?
• Breach Report – Do you give me a written report after a breach?
• Fix Steps – What are you required to do to fix the root cause?

How Do You Score Vendor Answers and Decide?

Give three points for a full written answer with proof. Give one point for a partial reply. Give zero for no answer. Add up the score for all 25 questions. A vendor below 50 out of 75 does not pass.

A tool for meeting notes carries less risk than one that holds payment data. Weight your scores by data type.

What Are the Final Access and Contract Questions?

The last five questions cover access and contract terms. Get these answers from a legal contact at the vendor. Not a sales rep. A sales rep cannot make binding promises. Get all five replies in writing. Do this before you sign.

• Single Sign-On (SSO) Support – Do you support SSO through Okta or Azure Active Directory?
• API Access – If I link your tool via API, is access tracked and logged?
• Role Controls – Can I set what each team member can see or do inside the tool?
• Liability – If a breach starts in your systems, what is your legal duty? Do you carry cyber insurance?
• Data at Cancellation – What happens to my data if I cancel or your company closes?

Frequently Asked Questions

What is an AI vendor security questionnaire for owner-operators?

An AI vendor security questionnaire is a written checklist. You send it to vendors before you sign. It covers data storage, breach notice, and compliance checks. It takes under two hours to finish. Written replies give you a record of the vendor’s security stance. Keep these on file. They can serve as proof if a dispute comes up. Verbal promises from a sales call cannot.

How many questions should the questionnaire include?

A practical questionnaire covers 20 to 30 questions. These span five areas: data handling, compliance, breach response, access controls, and contract terms. Fewer than 20 questions misses sub-processor rules. It also misses breach timelines. More than 30 questions can lower reply rates for smaller accounts. Twenty-five questions is the right number. It gives full coverage. It also gets a real reply from the vendor’s security team.

Do I need a lawyer to send this questionnaire?

You do not need a lawyer to write or send these questions. Each one is factual. No legal writing is needed. You do need a legal review before you sign. Get a lawyer to check the vendor’s answers on liability and DPA terms. A one-hour review costs $150 to $500. That fee is worth it for any AI contract that holds customer data.

What is a Data Processing Agreement and why does it matter?

A Data Processing Agreement is a legal contract. It defines how a vendor handles personal data under GDPR and CCPA. Without one, a regulator may hold your firm fully at fault. This can happen even if the breach starts in the vendor’s system. Any vendor that handles EU or California data must give you a signed DPA. Request it before you create an account.

What does SOC 2 Type II mean for a growing firm?

SOC 2 Type II is an outside audit of a vendor’s security controls. A certified accounting firm runs it over 12 months. It confirms those controls worked the whole time. The report covers access, privacy, and security in one place. Ask for a copy under NDA before you sign. A vendor who will not share it should be dropped from your list.

How long should a vendor take to respond to the questionnaire?

A vendor with written security policies should reply in 5 to 10 days. Vendors that take more than 10 days may have poor records. Watch for vendors who send a different form. That is a sign they are avoiding your questions. A fast and clear reply shows good readiness. A slow or vague reply means you should slow down your review.

What happens if a vendor scores below the passing cutoff?

If a vendor scores below 50 out of 75, you have three options. First, ask for written plans to fix the gaps. Do this before you sign. Second, add contract terms to cover weak areas. Third, choose a different vendor. Most small firms have little deal power. For them, switching tools is the safest path. This is true when gaps show up in data handling or breach response.

What US regulations apply to AI vendor security?

US firms that handle health data must follow HIPAA. They need a Business Associate Agreement (BAA) from any vendor that processes that data. Firms with California customers must follow CCPA. This applies when sharing personal data with vendors. The NIST AI Risk Management Framework is a free guide for AI vendor risk. It works for firms of any size.

Can I use this questionnaire at contract renewals?

Yes. Send it at each renewal. A vendor’s security stance can change between terms. They may add new AI features. They may also get acquired. Send the questionnaire at least 60 days before renewal. That gives you time to review and to negotiate. If the answers differ from your first review, treat the renewal as a full new check.

Is a vendor’s privacy policy the same as a security questionnaire?

No. A privacy policy is a public doc for users. It rarely covers encryption details. It also skips sub-processor lists, breach timelines, and liability limits. A security questionnaire asks the vendor to commit to exact details in writing. Review the privacy policy first. Then send the questionnaire. Use it to confirm the details match what you heard in sales.

Executive Summary

An AI vendor security questionnaire helps you vet any AI tool before your data enters a vendor’s system. It covers 25 questions across five areas: data handling, compliance, breach response, access, and contract terms. The IBM report puts the average breach at $4.88 million. Outside vendors are a growing source of that risk. A pre-contract review is the best step for firms with no IT team. Any vendor who cannot give written answers in 10 days should not hold your data. The same goes for vendors with no signed DPA or no SOC 2 report.

What Should You Do Next?

This week, list each AI tool your firm uses that holds customer data. For any tool where you lack a signed DPA, send the questionnaire before your next renewal date.
