ISO 22000 vs ISO 27018
ISO 22000
International standard for food safety management systems
ISO 27018
International code of practice for PII protection in public clouds.
Quick Verdict
ISO 22000 ensures food safety via HACCP and management systems for food chain firms, while ISO 27018 protects PII in public clouds as a 27001 extension for CSPs. Companies adopt them for certification, compliance assurance, and market trust.

ISO 22000 Details
What It Is
ISO 22000:2018 is the international certification standard for Food Safety Management Systems (FSMS). It applies to any organization in the food chain, providing a systematic framework to ensure safe food through hazard prevention, regulatory compliance, and chain-wide communication. It uses a risk-based approach with **two nested PDCA cycles—organizational for governance and operational for HACCP-aligned controls.
Key Components
- Clauses 4-10 follow High-Level Structure (HLS) for integration.
- Core elements: PRPs, hazard analysis, CCPs/OPRPs, traceability, verification.
- Built on Codex HACCP principles and management system discipline.
- Requires certification via accredited bodies with staged audits.
Why Organizations Use It
- Meets customer, regulatory demands; enables GFSI schemes like FSSC 22000.
- Reduces recalls, enhances supply chain resilience and market access.
- Builds trust with stakeholders; integrates with ISO 9001/14001.
Implementation Overview
- Phased: gap analysis, PRPs, hazard control plans, training, audits.
- Scalable for SMEs to multinationals across food sectors globally.
- Involves 6-18 months, internal audits, management reviews for certification.
ISO 27018 Details
What It Is
ISO/IEC 27018 is a code of practice extending ISO/IEC 27001 and ISO/IEC 27002 specifically for protecting personally identifiable information (PII) processed by public cloud service providers (CSPs) acting as PII processors. Published in editions including 2014 and the latest 2019, it addresses cloud-specific privacy risks like multi-tenancy, subprocessors, and cross-border flows via a risk-based control framework.
Key Components
- Approximately 25-30 additional privacy-specific controls mapped to ISO 27001 Annex A themes (organizational, people, physical, technological).
- Core principles: consent/choice, purpose limitation, data minimization, accuracy, retention limits, security, transparency, accountability.
- Integrated into ISO 27001 ISMS; assessed during certification audits via Statement of Applicability—no standalone certification.
Why Organizations Use It
- Accelerates procurement, builds customer trust, aligns with GDPR Article 28, HIPAA.
- Enhances cyber insurance, reduces security questionnaire friction.
- Provides competitive differentiation for CSPs demonstrating privacy stewardship.
Implementation Overview
- Gap analysis, ISMS updates, policy/contract revisions, training, technical safeguards (e.g., encryption, logging).
- Applicable to CSPs of all sizes globally; requires accredited third-party audits as part of ISO 27001 cycles.
