AI vendor due diligence questionnaire: [Vendor name]

[Organization name] is reviewing [Vendor name] before using its AI product. Please answer each question in writing and attach supporting documents where they exist. If a question doesn’t apply, say so and explain why. Please don’t answer with marketing material alone. We may follow up with questions or ask for a call.

About the company and the product

  1. Which models power the product? Are they your own or from a third party, and which providers act as subprocessors?
  2. How long has the product been in production, and how many customers like us use it?
  3. How do you notify customers of changes to models, features, terms, or pricing, and how much notice do you give?
  4. What can administrators see of our people’s conversations and activity, and what stays private to each user?

Data handling and privacy

  1. What data do you collect, store, and process on our behalf, and in which countries or regions?
  2. Is our data used to train or improve your models, or anyone else’s? Will you confirm in the contract that it is not?
  3. How long do you keep prompts, outputs, and logs? Can we set the retention period or ask for deletion?
  4. Who at your company and at your subprocessors can access our data, and how is that access approved and logged?
  5. What happens to our data when the contract ends, and how quickly is it deleted?
  6. How do you protect trade secrets and confidential information, and do your terms give you any rights in what we enter or what is produced?

Security

  1. Which independent security reports or certifications do you hold, such as SOC 2 Type II or ISO 27001? Can we see the most recent report?
  2. How is data encrypted in transit and at rest, and who manages the keys?
  3. Do you support single sign-on, multi-factor authentication, role-based access, and audit logs?
  4. How often do you run independent penetration tests, and how do you handle vulnerability reports?
  5. How do you defend against attacks specific to AI, such as prompt injection and data leaking between customers?
  6. If there is a breach or a serious incident, how quickly will you tell us, and what will you tell us?

How the AI behaves

  1. What are the known limitations and failure modes, and which uses do you advise against?
  2. How do you test the product for accuracy and safety? Can you share results for tasks similar to ours?
  3. Can we test it on our own examples before we sign?
  4. Do you keep logs of inputs and outputs that we can review when something goes wrong?

Contract and commercial terms

  1. Do the terms give us ownership of outputs? Do you offer protection if the outputs infringe someone else’s rights?
  2. What uptime, support response times, and service credits do you commit to?
  3. How is pricing set, what usage limits and overage charges apply, and what could change at renewal?
  4. What are your liability limits, and what cyber insurance do you carry?
  5. Can we export our data and settings, and what help do you provide if we leave?

How to use it

  1. Describe the purchase. Name your organization and the vendor, then say what kind of AI you’re buying.
  2. Say what it will touch. Check the data it will handle and how it will be used. The list adds the questions that matter for each.
  3. Copy or download it. Paste the questionnaire into an email or spreadsheet, or download it as a Markdown file. Have your security and legal teams review it, then send it.

AI vendor due diligence, explained

What is an AI vendor due diligence questionnaire?
A list of questions you send an AI vendor before you buy, to learn how it handles your data, how secure it is, how the AI behaves, and what the contract commits it to. The answers help you decide whether to buy and which risks to manage.
What should you ask an AI vendor?
Start with data: where it goes, how long it’s kept, who can see it, and whether it trains their models. Then ask about security reports and certifications, how the AI is tested for accuracy and bias, what controls you have, and what the contract says about ownership, liability, uptime, and exit. The generator above builds these from your answers.
Why does the list change when I check boxes?
The risks depend on what the vendor will touch and how it will be used. Health data adds questions about business associate agreements. Decisions about people add bias and automated-decision questions. Tools that act on their own add questions about approvals and limits.
What are warning signs in a vendor’s answers?
Vague or marketing-only answers, no written commitment on training with your data, no independent security report, refusal to let you test on your own examples, no clear exit terms, and no named person who can answer follow-up questions. Treat repeated evasion as an answer.
Should we ask for SOC 2 or ISO 27001?
They’re common, useful signs that a vendor has security controls independently checked. Ask for the latest report, not only the badge, and read the scope. They don’t cover AI-specific risks, which is why the questionnaire also asks about prompt injection, data separation, and model behavior.
Is this a legal or security review?
No. It is a general starting list. Your security, privacy, and legal teams should review it, and add anything your industry, regulators, or contracts require, before you send it.
