UK PSTI Product Security Applicability Test

Applicability Test decisions under UK PSTI Product Security should be written in operational language: who is in scope, what must happen, what evidence proves it, and when escalation is needed.

Use this guide to turn official requirements into scope, evidence, owner, and review decisions. This guidance is practical, source-linked, and should be validated against current legal and policy requirements before implementation.

Overview

This page helps you determine which UK PSTI Product Security duties apply by checking whether the product is a relevant connectable product. In practice, that means asking two simple questions: can it connect to the internet or a network, and is it not an excepted product? If the answer is yes, the product is in scope and the page helps you map the duty, owner, evidence, and review path.

Section 1

What should the UK PSTI Product Security Applicability Test decide?

Start by deciding whether the product is a relevant connectable product. Under the Act, that means a product that is either internet-connectable or network-connectable, and that is not an excepted product. If it is in scope, then work out which manufacturer, importer, distributor, statement of compliance, vulnerability disclosure, password, support-period, or OPSS enforcement duty is triggered.

Keep the legal source, product-scope decision, manufacturer/importer/distributor role, statement of compliance, and technical evidence together so OPSS-facing records are reviewable.

Define the exact Applicability Test trigger and the business process it affects.
Record which role, product, system, customer group, or data flow is in scope.
Attach the source-linked rule, the owner, and the evidence field before approving the control.
Escalate uncertainty when the facts depend on thresholds, exemptions, cross-border activity, vulnerable users, or enforcement-sensitive wording.

Section 2

Who should own the UK PSTI Product Security applicability test, and what evidence should prove the decision?

Ownership should sit with the team that controls product design, supply-chain placement, importer/distributor checks, or customer security information, with legal and product-security review.

Evidence should show relevant-connectable-product scope, default-password controls, vulnerability disclosure channel, minimum support period, statement of compliance, supply-chain role checks, and OPSS notice response readiness.

Name one accountable owner and one reviewer for the Applicability Test workflow.
Keep source screenshots or source links, decision notes, implementation tickets, and approval records together.
Use dated evidence for deadlines, notices, risk assessments, contracts, user journeys, and regulator-facing records.
Review the evidence after product changes, new markets, new vendors, enforcement updates, or material changes in the source text.

Section 3

Which edge cases should teams check before relying on a UK PSTI Product Security applicability test decision?

Most PSTI mistakes happen at the boundary between manufacturer, importer and distributor duties, excepted products, bundled products, support-period statements, and evidence that does not match the shipped product.

Use this section before UK market placement, importer onboarding, distributor acceptance, or support-period publication so the evidence matches the actual product and supply-chain role.

Check whether the rule changes for minors, consumers, business users, public-sector bodies, regulated sectors, high-risk services, or cross-border transfers.
Separate binding law, regulator guidance, consultation material, standards, and enforcement commentary in the evidence record.
Do not rely on a previous answer if the data categories, user interface, vendor role, or contractual flow changed.
Track unresolved assumptions in an open-questions section and route legal interpretation points for review.

Section 4

How should teams operationalize the UK PSTI Product Security applicability test with proportionate controls?

Use a compact PSTI workflow that captures product scope, role, password control, vulnerability disclosure route, support-period information, statement-of-compliance approval, and OPSS escalation path.

The output should be a product-scope note, statement-of-compliance pack, supplier attestation, customer-facing support-period notice, or OPSS response record.

Create a short intake question that identifies the Applicability Test scenario.
Map the answer to a required action, evidence field, owner, reviewer, and review date.
Link related artifact pages with descriptive anchors so users can move from scope to deadlines, controls, penalties, and templates.
Update the workflow when official source material changes or when internal evidence shows recurring exceptions.
