3 of 3 questions
Question 1

What must the manufacturer publish?

Since the regime took effect on 29 April 2024, the manufacturer must publish the minimum length of time for which security updates will be provided for the product and an end date. The information must be available without prior request, in English, free of charge, in an accessible, clear, and transparent form, and in language understandable without prior technical knowledge.

The published information must cover the update-capable product hardware and software categories described by Schedule 1 paragraph 3, including specified associated software used for the product's operation, user operation, or services. Use product names and model identifiers that let a customer match the notice to the item they own. If the manufacturer extends the minimum and creates a new , it must publish the new period as soon as practicable; it must not shorten the period after publication.

  • State a calendar end date, not only a duration such as 'three years'.
  • Explain what a means for the product without hiding the answer in technical release notes.
  • Make the information reachable without an account, support request, payment, or personal-data submission.
  • On a qualifying invitation to purchase on the manufacturer's own website or a free website under its control, publish the period alongside or with equal prominence to the product's main characteristics.

Question 2

How should teams control the published information?

Assign the notice to a product owner who can reconcile engineering support plans, third-party component commitments, and customer-facing copy. Keep the approval, product and software mapping, first-publication date, later versions, page captures, and change rationale.

PSTI sets no universal minimum number of years. The manufacturer chooses the period, but the published end date and the in the statement of compliance should agree. Review any proposed change against the current Regulations and preserve the earlier public record.

  • Check the notice during launch approval and after model, firmware, service, supplier, or end-of-life changes.
  • Keep redirects working if the notice moves, and retain a stable way to identify the supported model.
  • Separate security-update commitments from warranty, feature updates, general customer support, and product lifetime.

Question 3

What does publication not prove?

A visible end date does not by itself prove that the product is in scope, that the chosen date is operationally supportable, or that the manufacturer meets the password and vulnerability-reporting requirements. It also does not replace the statement-of-compliance, supply-chain, investigation, notification, remediation, or record duties.

If a manufacturer relies on a standards or labelling deemed-compliance route, keep evidence of the exact condition, covered product, version or label, and validity period. Do not describe a general ETSI assessment or expired scheme label as automatic PSTI compliance.
