AI Governance, Security & Compliance

AI vendor due diligence checklist

23 May 2026 6 min read

When you're considering integrating new AI tools into your small or medium-sized business, it's easy to get caught up in the potential benefits. Improved efficiency, new insights, enhanced customer service – these are all tempting prospects. However, before you sign on the dotted line, it's crucial to remember that AI solutions, like any technology, come with their own set of risks. Neglecting proper due diligence can expose your business to security vulnerabilities, compliance breaches, and unexpected costs.

This isn't about fostering paranoia; it's about intelligent risk management. A structured approach to evaluating AI vendors will help you distinguish between promising innovations and potential liabilities. It ensures that the AI you adopt genuinely serves your business needs without inadvertently creating more problems than it solves. This checklist provides a framework for conducting that essential due diligence, focusing on the critical areas of governance, security, and compliance.

Understanding the AI Solution Itself

Before delving into the vendor, you need a clear picture of the AI solution you're evaluating. This involves more than just understanding its headline features.

  • **Purpose and Functionality:** What exactly does the AI do? How does it achieve its stated goals? Is its purpose clearly defined and aligned with a specific business problem you need to solve? Be wary of vague descriptions or overly broad claims.
  • **Data Inputs and Outputs:** What kind of data does the AI require to function? Where does this data come from (your systems, public sources, third-party feeds)? What kind of data does it produce as output? Understand the sensitivity of this data.
  • **Accuracy and Reliability:** How accurate is the AI's output? Is there a quantifiable measure of its reliability? For instance, if it’s a predictive tool, what's its typical error rate? Are there scenarios where its accuracy might degrade significantly?
  • **Explainability (XAI):** Can the AI’s decisions or outputs be explained in a way that a human can understand? For many business applications, particularly those involving critical decisions or customer interactions, "black box" AI models can be a significant liability from a governance and accountability perspective.
  • **Human Oversight and Intervention:** Is there a clear process for human review, oversight, and intervention when the AI is in use? What are the capabilities and limitations of this human oversight? No AI should operate entirely autonomously in a business context without careful consideration.
  • **Scalability and Performance:** Can the AI solution scale with your business growth? What are its performance metrics under various loads? Will it integrate smoothly with your existing IT infrastructure?

Data Security and Privacy Practices

Data is the lifeblood of most businesses, and AI often interacts directly with it. Robust data security and privacy practices are non-negotiable.

  • **Data Encryption:** Is data encrypted both at rest (stored) and in transit (moving between systems)? What encryption standards are used?
  • **Access Controls:** How does the vendor manage access to your data within their systems? Are robust access controls, multi-factor authentication (MFA), and least privilege principles applied?
  • **Data Storage Location:** Where will your data be stored? Is it within the UK or EEA? If not, what international data transfer mechanisms are in place, and what are the implications for GDPR compliance?
  • **Data Retention Policies:** What are the vendor's data retention policies? How long do they keep your data, and what is the process for data deletion requests once you stop using their service?
  • **Incident Response Plans:** Does the vendor have a clear and established incident response plan in the event of a data breach or security incident? What are their notification procedures, and how quickly would you be informed?
  • **Privacy by Design:** Does the vendor demonstrate a commitment to privacy by design principles throughout the development and operation of their AI solution?
  • **Sub-processors:** Does the vendor use any sub-processors (other third parties) that will also handle your data? If so, have they conducted due diligence on those sub-processors, and do their contracts reflect your data protection requirements?

Compliance and Legal Considerations

Operating in the UK, your business must adhere to a range of regulations. Your AI solutions must support, not hinder, that compliance.

  • **GDPR Compliance:** Does the vendor understand and comply with the General Data Protection Regulation (GDPR)? Can they provide evidence of their compliance, such as independent audits or certifications?
  • **Industry-Specific Regulations:** Are there any industry-specific regulations relevant to your business (e.g., in finance, healthcare, legal)? Does the AI solution meet these requirements, or can it be configured to do so?
  • **Intellectual Property (IP):** Who owns the IP rights to the AI's outputs? If the AI generates content or insights, is there any risk of infringing on third-party IP? What are the vendor's policies regarding your data being used to train their models, and what are the IP implications if it is?
  • **Ethical AI Guidelines:** While not always legally binding, does the vendor have a stated commitment to ethical AI principles? How do they address issues like bias, fairness, transparency, and accountability in their AI development?
  • **Audit Trails:** Does the AI solution provide robust audit trails of its activities, inputs, and outputs? This can be crucial for accountability, troubleshooting, and demonstrating compliance.
  • **Contractual Terms:** Review the terms and conditions meticulously. Pay particular attention to clauses on data ownership, liability, service level agreements (SLAs), termination clauses, and dispute resolution. Seek legal advice if necessary.

Vendor Stability and Support

The best AI solution is only as good as the company behind it. Assess the vendor's long-term viability and their commitment to customer support.

  • **Company Background:** How long has the company been in business? What is their financial stability? Are they well-funded? A start-up might offer innovative solutions but could present a higher risk of going out of business.
  • **Track Record and References:** Can the vendor provide references from similar businesses that are using their AI solution? Are there case studies or testimonials available?
  • **Support and Maintenance:** What level of ongoing support and maintenance do they offer? What are the response times for critical issues? Is support available during your business hours?
  • **Updates and Upgrades:** How frequently is the AI solution updated and improved? What is their roadmap for future development? How are these updates deployed, and is there any potential disruption?
  • **Training and Documentation:** What training resources and documentation are available to help your team effectively use the AI solution?

Cost and Return on Investment (ROI)

Beyond the initial purchase price, the true cost of an AI solution can be complex.

  • **Total Cost of Ownership (TCO):** Beyond the licensing fee, what are the ongoing costs? Include data storage, processing power, integration costs, training, and potential customisation.
  • **Pricing Model Transparency:** Is the pricing model clear and transparent? Are there hidden costs, usage limits, or unexpected fees for exceeding certain thresholds?
  • **Implementation Costs:** What are the costs associated with integrating the AI solution into your existing systems and workflows?
  • **Measuring ROI:** How will you measure the return on investment for this AI solution? What metrics will you use to determine its success? The vendor should be able to help you define these if their solution genuinely delivers value.

Adopting AI can be a transformative step for your SME. By taking a thoughtful, systematic approach to vendor due diligence, you can mitigate risks and ensure that your investment pays off, fostering innovation safely and securely. Don't rush into decisions; a little scrutiny now can save you significant trouble later. If you need help navigating these considerations, particularly with tools like Microsoft Copilot, consider seeking expert advice.
