ISO/IEC 27701 has been one of the world’s most important privacy standards, helping organizations convert ISO 27001 into a full Privacy Information Management System (PIMS). With the release of ISO/IEC 27701:2025, the standard has undergone a significant overhaul, making it more aligned with global privacy laws and more scalable for modern organizations using cloud, SaaS, AI, and distributed systems. This blog explains EVERY key change from the 2019 version, based on the official 2025 edition, and is designed to rank highly in Google Search and AI Search.
Overview: What Changed in ISO/IEC 27701:2025?
The new 2025 edition is not just an update — it is a full redesign of the standard. Top Highlights
27701:2025 is now a standalone management system standard (no longer an extension of ISO 27001).
New structure aligned with Annex SL (like ISO 27001:2022, ISO 9001:2015, ISO 45001:2018, etc.)
Several 2019 controls removed
New controls added for modern privacy threats
Many controls merged or revised for clarity
Strong focus on privacy-by-design, deidentification, cloud, and subcontractors
More guidance for PII Controllers + PII Processors
Enhanced control mapping with GDPR, ISO 29100, ISO 27018, ISO 29151
1. The Biggest Change: It Is Now a Standalone Standard In 2019:
ISO 27701 was only an extension to ISO/IEC 27001. In 2025, ISO 27701:2025 is a complete management system standard on its own.
Impact on organizations
You can now certify a PIMS without mandatory ISO 27001 certification.
Easier adoption for privacy centric companies not seeking a full ISMS.
More flexibility for cloud providers, SaaS, and data processors.
2. New, Fully Rewritten Structure
The 2025 edition uses the standard Annex SL format, aligned with ISO 27001:2022:
Clause | Topic |
1 | Scope |
2 | Normative references |
3 | Terms & definitions |
4 | Context |
5 | Leadership |
6 | Planning |
7 | Support |
8 | Operation |
9 | Performance evaluation |
10 | Improvement |
What’s new?
A full risk based PIMS lifecycle (planning → operation → evaluation → improvement)
Dedicated risk assessment and risk treatment sections
Dedicated management review requirements
Mandatory PIMS objectives and documented information management
This brings ISO 27701 closer to ISO 27001, ISO 9001, ISO 22301, etc.
3. Major Control Changes (Removed, Added, Mapped)
Annex F of the new standard provides a detailed mapping with ISO 27701:2019. Here are the big takeaways:
A. Controls Removed from 27701:2019
Many controls from 2019—especially those duplicating ISO 27001 content—have NOT been included in 2025. Examples of removed controls
Segregation of duties
Contact with authorities
Contact with special interest groups
Inventory of information assets
Return of assets
Handling of removable media
Management of technical vulnerabilities
Malware controls
Secure development environment
System acceptance testing
Information systems audit controls
Physical security controls (e.g., perimeters, entry, cabling)
Network security and segregation
Cloud service supply chain controls
Why removed? Because 2025 is meant for PIMS only and does NOT repeat controls already in ISO 27001:2022 or ISO 27002.
B. New Controls Added in 27701:2025
Although many controls were removed, several brand-new additions appear, especially in Annex A. Key new control topics
Threat intelligence (modern privacy threat awareness)
Cloud service–specific expectations
Information deletion
Data masking
Data Leakage Prevention (DLP)
Monitoring activities
Secure coding
ICT readiness for business continuity
Physical security monitoring
Why added? They address:
Cloud privacy risks
Multicounty data transfer complexity
AI driven and automated processing risks
Modern cyberprivacy threats like DLP & data exposure
C. Controls That Are Completely New in 2025
Annex A For PII Controllers
New requirements for transparency
New deidentification guidance
Strengthened privacy by-design controls
More detailed privacy impact assessment (PIA) requirements
For PII Processors
New subcontractor obligations
Mandatory customer notifications for jurisdiction changes
Enhanced disclosure, transfer & data return requirements
For Both Controller + Processor
New security controls specific to PII
Mandatory logging, secure authentication, identity lifecycle
Stronger backup & restoration rules
Clear requirements for cryptography & key management
4. New and Detailed Mapping Sections
The 2025 edition contains updated and expanded mappings: Updated mappings include:
Mapping to ISO 29100
Mapping to GDPR Articles 5–49
Mapping to ISO 27018 (cloud PII processors)
Mapping to ISO 29151 (PII protection controls)
Mapping to 27701:2019 (Annex F)
These mappings help with:
GDPR compliance demonstration
Contractual compliance for cloud/subcontractors
Privacy impact assessments
International data transfer compliance
5. Strong Guidance for Risk Assessment & Privacy Impact Assessment
Compared to 2019, the 2025 version introduces:
Clear privacy risk criteria
Mandatory risk owners
Specific risk evaluation requirements
Mandatory privacy risk treatment plan
Mandatory statement of applicability
Well-defined PIA guidance, aligned with ISO 29134
Explicit consideration of risks to PII principals, not just the organization
This makes the 2025 version more stringent and audit friendly.
6. Clean Separation Between Controller & Processor Controls
The New Annex A is fully reorganized:
Table A.1 — Controls for PII Controllers
Table A.2 — Controls for PII Processors
Table A.3 — Security Controls for Both
This separation is clearer, more logical, and reduces overlap.
7. Expanded Guidance Annexes (Annex B)
Annex B nearly doubles the guidance content compared to 2019. It includes deep guidance on:
Privacy notices
Consent management
Transparency
Deidentification techniques
Transfers & disclosures
Temporary files
Data retention schedules
Automated decision making
Cloud subcontractor management
This makes ISO 27701:2025 significantly more practical.
8. A More Modern, Cloud Ready, AI Ready PIMS
The new standard directly supports:
Cloud-based processing
AI/automated decision-making
Multijurisdictional transfers
Distributed supply chains
High scale SaaS providers
Privacy risk assessment for modern systems
Deidentification & data minimization at scale
2019’s version did not fully address these realities.
If your organization processes PII, especially across borders or using cloud platforms, then ISO/IEC 27701:2025 provides a comprehensive, more modern, more globally aligned framework than the 2019 edition.
