Annex A 5.22 verified ISO/IEC 27001:2022
Monitoring and Managing Supplier Services
Keep track of and adapt to changes in how suppliers handle security and service delivery.
record_voice_over
Plain language
Think of this as keeping a close eye on the services your suppliers provide to ensure they are following the security and service rules you both agreed on. If this isn't done, a supplier might change something important, like their security settings, without your knowledge. This could leave the door open for data breaches or service disruptions, which could hurt your business or reputation.

Why it matters
Without monitoring supplier services, unnoticed security changes can lead to data breaches, loss of trust and financial impacts.

Operational notes
Regularly review supplier security reports; trigger deeper evaluations on changes, incidents, or contract renewals to ensure compliance.

Implementation tips
- The procurement manager should include clear security terms in contracts with suppliers. Ensure these terms outline security expectations, how often service reviews will occur, and what happens if standards are not met. This aligns with ISO 27002:2022 guidance and helps ensure suppliers meet agreed security practices.
- An IT manager should regularly monitor supplier performance against contracted security measures. This can be achieved by setting up routine checks and evaluations of supplier systems and processes, verifying they meet requirements laid out in agreements.
- The compliance officer should organise audits of suppliers’ operations. Use external audits when necessary, and complement with internal review of suppliers’ compliance with security practices. Follow the CPS 234 and reference ISO 27002:2022 to ensure comprehensive evaluations.
- The supplier relationship manager should schedule regular meetings with suppliers to discuss and review service reports and incident responses. This promotes open dialogue about any issues and ensures all parties are aligned on security needs.
- IT staff should track any technological changes or upgrades by the supplier that could affect security or service delivery. Update security checks to include these changes and ensure continuity of services as per agreement.
03 - Audit

Audit / evidence tips
- AskRequest service level agreements and any security addendums with suppliers. GoodAgreements reference specific security practices and contain provisions for monitoring and audits.
- AskAsk for records of service reviews or performance assessments conducted on suppliers. GoodDocumentation shows routine monitoring and matches contracted frequency.
- AskRequest logs of meetings and communications with suppliers discussing service changes and security incidents. GoodMeetings and follow-up actions are documented, showing proactive management.
- AskAsk for audit reports or certificates obtained from or about the suppliers. GoodReports indicate thorough audits have been conducted with satisfactory compliance results.
- AskRequire documentation of supplier changes affecting information systems. GoodChange logs detail what was updated and when your organisation was informed.
