Supplier Assurance Questions

Government Guidance2026UK National Cyber Security Centre

What does it cover?

UK government guidance describing areas organisations may examine when assessing suppliers and their technical/security posture.

Key points

01Supplier assurance can include governance, incident recovery, cloud configuration, privileged access, bespoke software security, data handling, testing and certification.
02Buyers are encouraged to consider whether certification scope actually covers the service they use.
03Supplier risk may need to be reconsidered as technology, data and operating conditions change.

Why it matters. Lornets interpretation.

Enterprise scrutiny is fundamentally about whether technical claims relevant to the customer can be substantiated by evidence that is current and in scope.

This is the Lornets reading of the source, not a finding of the source itself.

What it does not establish

01The questions are guidance rather than one mandatory universal procurement checklist.
02Different buyers and sectors may require materially different evidence.
03NCSC guidance does not mean every enterprise customer will request every listed assurance area.
