What carries over from ISO/IEC 27001 to ISO/IEC 27701
Your ISMS is most of the way to a PIMS. The clauses are shared, ISO/IEC 27701 asks you to document the information security programme you run — your ISMS is exactly that — and its 29 security controls are ISO/IEC 27001 controls applied to PII. The new work is privacy itself: your controller and processor roles, a privacy policy, privacy risk that weighs the consequences for people, and the 49 controller and processor controls.
Of the 103 clauses and controls ISO/IEC 27701 asks for: 38 to reuse, 22 to extend and 43 new.
- 38 Reuse Use what you have: the same process or document, with its scope widened.
- 22 Extend Keep what you have and add the new standard’s content.
- 43 New Nothing you have covers it: new work.
Do I need to rewrite my policies?
No. Keep your security policy set: ISO/IEC 27701 expects security policies related to PII processing (A.3.3), and yours can carry them. Add a privacy policy with privacy commitments — or a clearly marked privacy section of an integrated policy — and the privacy procedures your controller and processor duties need, such as handling requests, retention and disposal, and engaging subcontractors.
The management system, clause by clause
Both follow the harmonised structure that ISO management-system standards share, so clauses 4 to 10 line up by number. Each row says what ISO/IEC 27701 asks for and what to do with what your ISMS already has.
| Clause | Your ISO/IEC 27001 | ISO/IEC 27701 asks for | What to do |
|---|---|---|---|
| 4.1 Context | Internal and external issues that affect what the ISMS is meant to achieve — including, since the 2024 amendment, whether climate change is relevant. | Issues that affect the PIMS, including whether climate change is relevant, and whether the organisation acts as a PII controller (alone or jointly), a PII processor or both. | Extend Add the privacy laws and contracts that apply, and decide where you act as a PII controller (alone or jointly) and where as a processor. |
| 4.2 Interested parties | Who has a stake in information security, what they require, and which of those requirements the ISMS will address. | Who has a stake in the organisation’s handling of PII — the people it relates to, customers, regulators, processors — and what they require. | Extend Keep what your ISMS has here, and add what ISO/IEC 27701 asks for. |

Controls: ISO/IEC 27701 Annex A, against ISO/IEC 27001 Annex A
Table A.3 of ISO/IEC 27701 applies 29 ISO/IEC 27001 controls to PII processing, so those carry straight over. Tables A.1 (controllers) and A.2 (processors) are privacy controls; only some have a security counterpart.

A route from ISO/IEC 27001 to ISO/IEC 27701
-
Roles and scope
- Map your processing and decide, for each activity, whether you act as PII controller (alone or jointly) or processor
- List the privacy laws and contracts that apply
- Set the PIMS scope and how it relates to the ISMS scope
-
Gap assessment
- Go through this page clause by clause
- Table A.3 security controls: confirm your ISMS covers PII processing
- Tables A.1 and A.2: check the controller and processor controls that apply to you
-
Governance
- A privacy policy approved by top management
- Responsibility for the PIMS and its reporting assigned
- Privacy objectives set and measured
-
Risk
- Extend the risk method to privacy risks and their consequences for people
- Privacy impact assessments for new or changed processing (A.1.2.6)
- Document your ISMS as the information security programme, and write the Statement of Applicability against ISO/IEC 27701 Annex A
-
Controls
- As controller: purposes, lawful basis, consent, rights, privacy by design, transfers
- As processor: customer instructions, help with their obligations, subcontractors, return and disposal, disclosure requests
-
Run and check
- Operate the PIMS and keep its records
- An internal audit covering both roles
- A management review with the PIMS inputs
-
Certification
- Ask your certification body about auditing the PIMS with the ISMS, and whether it is accredited for the 2025 edition
Certification and audits
- Since the 2025 edition, ISO/IEC 27701 is certified on its own: you don’t need ISO/IEC 27001 first, and the two certificates are separate.
- Integrated audits are common when both systems share processes. Ask your certification body whether it is accredited for ISO/IEC 27701:2025, since accreditation was still being extended after publication.
- Certification to ISO/IEC 27701 shows a working privacy management system. It is not certification of compliance with any particular privacy law.
Common pitfalls
- Calling yourself “the processor” for everything, when you are a controller for your own staff, customers’ billing contacts and marketing.
- Rating privacy risks only by their consequences for the organisation.
- Reusing the ISMS Statement of Applicability instead of writing one against ISO/IEC 27701 Annex A.
- Working from the 2019 edition, which extended ISO/IEC 27001 and 27002, instead of the standalone 2025 one.
- Treating a PIMS certificate as proof of GDPR or DPDP Act compliance.
