Introduction

On 14 October 2025 the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) published the second edition of ISO/IEC 27701:2025 — Information security, cybersecurity and privacy protection — Privacy information management systems — Requirements and guidance. The revised standard transforms privacy from an extension of information security into a fully standalone, certifiable Privacy Information Management System (PIMS).

Background / Context

First published in 2019 as an extension to ISO/IEC 27001, ISO/IEC 27701 provided organisations with a structured approach to document, manage and demonstrate privacy controls for both controllers and processors. The 2025 edition responds to rapid regulatory change, the proliferation of AI and automated processing, cloud-first architectures, and increasingly complex cross-border data flows by elevating privacy governance into a distinct management discipline.

What changed — headline overview

• Stand‑alone PIMS: ISO/IEC 27701:2025 contains its own management system clauses (Clauses 4–10), enabling organisations to implement and certify a PIMS independently of an ISO/IEC 27001 ISMS.
• Controller & processor parity: Expanded, clearer guidance for both personal data controllers and processors with dedicated control objectives and implementation guidance.
• AI, digital ecosystems & cloud: Explicit coverage of privacy risk in AI/ML, automated decision‑making, cloud services and large‑scale data processing.
• Governance & leadership: Stronger emphasis on embedding privacy in leadership, strategic planning, performance metrics and continual improvement cycles.
• Regulatory alignment: Designed to align with global privacy frameworks (GDPR, CCPA, LGPD and others) and to be integrable with ISO 9001, ISO/IEC 27001 and ISO/IEC 42001.

Technical details & structure

The 2025 edition reorganises material so organisations can treat privacy as a complete management system. The standard draws on existing normative requirements and guidance found in ISO/IEC 27701:2019, ISO/IEC 27001:2022 and ISO/IEC 27002:2022, but repackages those elements into a self‑contained PIMS. Notable structural elements include:

• Management system clauses (4–10) tailored for PIMS.
• An Annex listing control objectives for controllers and processors and a companion annex with best‑practice implementation guidance.
• Backwards compatibility annexes to assist organisations and auditors in mapping 2019 implementations to the 2025 edition.

Timeline of events

• 2019 — ISO/IEC 27701 published as an extension to ISO/IEC 27001.
• 2024–2025 — Revision work, Final Draft International Standard (FDIS) and balloting stages.
• 14 October 2025 — ISO/IEC 27701:2025 published as the second edition.
• 2025–2028 (expected) — Accreditation bodies, certification bodies and organisations plan transition windows and certification availability; bodies typically provide transition timelines that can span up to three years.

Main changes — detailed breakdown

Standalone management clauses

By including its own clauses, the new standard allows organisations without an ISMS to adopt PIMS as a primary management system while still enabling straightforward integration with existing ISO standards for organisations that prefer combined management systems.

Enhanced risk management orientation

Privacy risk assessment and treatment are now explicitly described as PIMS responsibilities rather than being dependent on ISMS processes. The 2025 edition clarifies risk owner roles, risk acceptance criteria, and links to organisational risk appetite.

Controller and processor controls

Annexes now separate control objectives and controls for controllers and processors. Processors receive expanded implementation guidance to help demonstrate contractual and technical measures required by modern data protection law.

AI and automated processing

The 2025 text calls out privacy considerations in AI systems (data provenance, consent, fairness and explainability) and recommends layered controls where model development, data pipelines, and deployment environments intersect with personal data.

Governance, KPIs and continual improvement

Expect clearer requirements for leadership commitment, privacy performance metrics, privacy impact assessment processes, and management review routines focused on privacy outcomes.

Transition, certification and accreditation — practical guidance

• Transition rules: Formal transition rules and certification processes are set by accreditation bodies and are expected to be published following the ISO release. Historically, ISO revisions follow a transition period of up to three years, but organisations should confirm timelines with their certification bodies and national accreditation bodies.
• Preparation steps: Conduct a gap analysis against the 2025 clauses, update PIMS scope and documentation, map existing ISO/IEC 27701:2019 controls to the 2025 Annexes, and pilot privacy KPIs and governance changes.
• For organisations without ISO/IEC 27001: The standalone PIMS option opens certification to entities that previously could not obtain ISO/IEC 27701 without an ISMS—this will require readiness planning focused purely on privacy management instead of information security prerequisites.

Impact and scope

ISO/IEC 27701:2025 reshapes the privacy certification ecosystem by:

• Enabling a broader set of organisations (including privacy‑first service providers and data‑centric businesses) to pursue standalone privacy certification.
• Increasing the demand for qualified auditors and consultants with privacy management expertise — raising potential market pressure on certification timelines.
• Helping organisations translate regulatory obligations into auditable management practices, potentially simplifying multi‑jurisdictional compliance.

Response & mitigation advice for organisations

1. Start with a targeted gap assessment against the published 2025 clauses.
2. Update the PIMS scope and governance — clarify controller vs processor responsibilities.
3. Map controls and evidence to the new Annex structure and adopt measurable KPIs.
4. Strengthen AI/data pipeline controls — provenance, consent records, model governance and vendor oversight.
5. Engage your certification body early to understand transition timelines and accreditation expectations.

Expert commentary

Privacy professionals and certification bodies have welcomed the change. Making privacy an independent, certifiable management discipline underscores the maturity of privacy practice and enables organisations to treat privacy risk on par with other enterprise risks.

Outlook

Expect a phased market response: early adopters and privacy‑first vendors will pursue certification in 2026, while many organisations will use the three‑year transition window to align governance and evidence. Over time, ISO/IEC 27701:2025 should help standardise privacy assurance and reduce friction in cross‑border data exchanges.
