ISO/IEC 27018:2025 for DPOs
What does ISO/IEC 27018:2025 require of a DPO?
The ISO/IEC code of practice for a public cloud provider acting as PII processor, third edition (August 2025), realigned to ISO/IEC 27002:2022: public cloud PII guidance on 13 ISO/IEC 27002:2022 controls (policy and responsibility split, PII contact, media transfer records, compromised credentials and customer-managed access, breach determination, independent evidence, awareness, disposal, customer account log-on, backup, logging, cryptography information, PII in testing) and 25 Annex A controls under the ISO/IEC 29100 principles, now marked informative (principal rights, instruction-only processing, no marketing use, temporary files, disclosure notification and records including the reason, sub-contractor disclosure, breach notification, policy retention, return and disposal, confidentiality, hardcopy, restoration logs, media, encryption in transit, user IDs, contract measures, sub-contractor contracts, pre-used storage, data location, intended destination). Under ISO/IEC 27018:2025, which defines 38 controls, a DPO's work is deciding which controls you own outright, which you share and which belong to another team, then holding the evidence for the first group.
Which ISO/IEC 27018:2025 controls land on the DPO
Data Protection Officers oversee privacy compliance, manage data subject rights requests, conduct privacy impact assessments, and serve as the point of contact with data protection authorities. The role is mandatory under GDPR for many organisations.
ISO/IEC 27018:2025 defines 38 controls across 5 domains that directly affect the DPO role. Understanding which controls fall within your ownership, which are shared, and which are owned by other teams is the foundation of effective compliance management.
What a DPO is accountable for under ISO/IEC 27018:2025
Advising the organisation on data protection obligations and best practices
Managing data subject access requests (DSARs) and privacy complaints
Conducting data protection impact assessments (DPIAs) for new processing activities
Maintaining records of processing activities and data flow maps
Serving as the liaison with data protection supervisory authorities

Challenge 3
Keeping privacy notices and consent mechanisms current across all channels
Challenge 4
Responding to DSARs within regulatory timeframes at scale
Challenge 5
Assessing privacy implications of AI and automated decision-making systems
