FAQs

Does ISO 27001 require supplier or vendor risk assessments?

Yes. ISO 27001:2022 Annex A control 5.19 requires organizations to identify, assess, and manage information security risks introduced by suppliers. Clauses 6.1 and 8.2 extend this into the core risk assessment process, placing vendor risk squarely inside ISMS scope. 

How often should you reassess supplier risk under ISO 27001?

ISO 27001 doesn't set a fixed schedule. Most organizations review high-risk (Tier 1) suppliers annually, medium-risk suppliers every two years, and low-risk suppliers on a lighter cycle. Reassess immediately after a breach, ownership change, or expanded system access, regardless of the regular schedule. 

Which ISO 27001 Annex A controls cover supplier risk?

Five Annex A controls govern supplier management: 5.19 (information security in supplier relationships), 5.20 (security terms in supplier agreements), 5.21 (ICT supply chain risk), 5.22 (monitoring and review of supplier services), and 5.23 (security for cloud services). 

Do all vendors need the same level of ISO 27001 risk assessment?

No. ISO 27001 uses a risk-based approach. Vendors handling sensitive data or supporting critical systems need deeper due diligence and more frequent review, while low-access suppliers, such as office vendors, need only lighter, periodic checks.
