Platform / Supplier assurance

Understand the AI behind the service you buy.

Buying AI does not remove responsibility for how it is selected, configured and used. Teams need a proportionate way to ask suppliers for the facts and evidence their own governance depends on.

External AI assurance

See supplier questionnaires, buyer assurance, corrective actions and time-limited specialist review in a hypothetical workspace. All organisations, people and systems shown were created for demonstration, and no client data appears.

AI governance does not stop at the edge of the organisation. EU AI Fit connects suppliers to the systems and components that depend on them. A secure questionnaire lets a supplier respond without entering the client workspace, and the response remains pending until an authorised reviewer checks it.

The reviewer records available evidence, gaps, conditions, actions and a reassessment date. Buyer assurance has a different purpose: each answer is tied to a system, owner and evidence reference, then reviewed before a locked response pack is supplied.

Where additional judgement is needed, an independent specialist receives a frozen snapshot rather than unrestricted access. Credentials, independence, sources, decisions, limitations and attestation are retained. Material change makes the opinion visibly out of date instead of silently rewriting history.

Why this matters

A vendor questionnaire becomes obsolete as soon as the product changes.

AI suppliers, products, models and sub-processors change at different speeds. An answer stored only in email is difficult to connect to the systems that rely on it or to revisit when the supplier announces a material update.

EU AI Fit keeps the supplier response, evidence and reviewer decision linked to affected systems, including conditional approval and follow-up actions.

Who it is for

The teams responsible for selecting, operating and challenging third-party AI.

  • Procurement and supplier-management teams
  • System owners relying on third-party AI
  • Security, privacy and compliance reviewers
  • Suppliers responding without needing a workspace account

How the work moves

Connect supplier facts to a controlled use decision.

  1. 01

    Map the dependency

    Connect the supplier, product, model/version and relevant sub-services to every affected AI system.

  2. 02

    Request the right facts

    Issue a secure, time-limited questionnaire scoped to the use and evidence required.

  3. 03

    Review the response

    Evaluate answers and supporting material, record limitations and open targeted remediation.

  4. 04

    Approve with control

    Approve, approve conditionally or decline, then set a review date and material-change triggers.

In this scenario

A supplier changes the foundation model behind a customer feature

The commercial product name stays the same while the underlying model and data-handling terms change.

The product and model are separately linked, so the change can trigger reassessment for each relying system.

The supplier is asked only for the new facts and evidence. Existing accepted material remains in the history rather than being overwritten.

The team can explain the basis and conditions of continued use without restarting an unrelated generic questionnaire.

What is retained

A supplier decision with conditions that can be revisited.

The supplier-assurance workflow connects each answer and condition to the systems that depend on it.

  • Supplier, product and model register
  • Dated questions, responses and evidence
  • Reviewer findings and limitations
  • Approval or conditional-approval decision
  • Remediation actions and reassessment triggers
