Available on request

  • Independent security assurance

    Evidence found

    A current SOC 2 report or ISO/IEC 27001 certificate is the usual evidence that a supplier operates appropriate security measures.

    A penetration test report, a completed standard questionnaire (SIG, CAIQ, HECVAT) or security documentation shows how the supplier tests and runs its controls.

Article 28(3)

Put processing under a written contract

    No public evidence

    The DPA is where processing instructions, confidentiality, security, sub-processing and audit rights are written down.

Article 28(2) and (4)

Know and control sub-processors

A processor may engage another processor only with the controller’s prior authorisation, must inform the controller of intended changes so it can object, and must flow the same data protection obligations down by contract.

Evidence found

  • Published subprocessor list

    Evidence found

    A current list of subprocessors, with purpose and location, is how a customer knows who else touches its data.

Article 33(2)

Available on request

  • Incident response and notification

Transfer data outside the EU lawfully

Transfers of personal data to a third country need an adequacy decision or appropriate safeguards such as standard contractual clauses, and the controller needs to know where the data goes.

  • Transfer mechanism

    No public evidence

    Transfers outside the EU or UK need a basis such as an adequacy decision (including the EU-US Data Privacy Framework) or standard contractual clauses.

  • Where data is hosted and processed

    Evidence found

    The regions or countries where the service runs and data is stored, from the vendor or its subprocessor list.

Questions buyers ask

Is Stell Engineering GDPR compliant?

CertReports does not decide that. It shows the public evidence that may support each GDPR requirement that reaches vendors: evidence was found or is available on request for use processors that provide sufficient guarantees (Article 28(1)), know and control sub-processors (Article 28(2) and (4)), be told of breaches without undue delay (Article 33(2)), and nothing public was found for put processing under a written contract.

What should I ask Stell Engineering for?

Request security testing and documentation, incident response and notification, data processing agreement, and confirm each is current.

This maps third-party obligations to the vendor evidence that may support them. It is not legal advice and never a statement that a vendor or its customers comply; confirm scope and sufficiency with your counsel or auditor. “No public evidence” means nothing public was found at the last check. Citations link to the official text.

Requirements reviewed 21 Sep 2026. The vendor lists the evidence on its trust centre behind a request or NDA; ask for it.
