ISO/IEC 27018:2019 Code of Practice for Protection of Personally Identifiable Information (PII) in Public Clouds is issued by International Organization for Standardization (ISO) / International Electrotechnical Commission (IEC) and applies most commonly in Global. This page covers who typically pursues it, what drives the decision, and when it's worth the investment.
Who ISO 27018 Applies To
ISO 27018 is most relevant to:
- Saas
- Enterprise
- Cloud Providers
Industries That Pursue ISO 27018
Teams working in the following sectors regularly engage with ISO 27018:
- Technology
- Healthcare
- Finance
- Cloud Services
- Professional Services
Common Drivers
Organizations typically pursue ISO 27018 for one or more of:
- Customer or enterprise procurement: prospects or existing customers require it as part of security review and vendor onboarding.
- Regulatory obligation: ISO 27018 audits are formally required and gated by regulators or auditors.
- Risk reduction: the control framework surfaces real gaps — access management, change control, incident response — that would eventually bite without structure.
- Market signal: many buyers now treat the framework as a trust shortcut; achieving it accelerates sales cycles.
Where It Applies
ISO 27018 is recognised in Global. If you sell outside those regions, confirm whether buyers will accept ISO 27018 or whether a locally-recognised alternative is required.
Alternatives and Adjacent Frameworks
If ISO 27018isn't the right fit, buyers in the same space typically also accept:
Decision Checklist
- Is a customer or regulator asking for it in writing?
- Will the audit output be used repeatedly across prospects, or just once?
- Do you have the budget and six-month calendar required to see the process through?
- Could an adjacent framework (ISO 27001 or ISO 27017) satisfy the same ask more cheaply?
