A.5.22 Monitoring, review and change management of supplier services
On a regular basis the organization is to monitor, review and evaluate suppliers' security practices and service delivery and to manage changes to them. Purpose (stated in ISO/IEC 27002:2022): keeps security and service delivery at the levels the supplier agreements set. As an Annex A reference control, it is compared with the controls determined in risk treatment (6.1.3 c) and recorded in the Statement of Applicability as included or excluded, with the justification and implementation status (6.1.3 d); implementation guidance is ISO/IEC 27002:2022 5.22.

Clauses 4 to 10 are the management-system requirements: none of them can be excluded when an organisation claims conformity. The 93 Annex A controls are a reference set: one may be excluded with a justification in the Statement of Applicability. Certification bodies assess conformity; the evidence lists here are what auditors commonly ask for, not a list the standard prescribes.
These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.

Common gaps auditors find
- Supplier changes such as moving hosting location or adding sub-processors happen without notice or review
- Assurance reports are filed but exceptions in them are never followed up
- No one is accountable for monitoring security performance of a given supplier
- Supplier incident information is not integrated into the organization's incident process
