ISO 27701:2025: What Changed and Who Needs It
ISO/IEC 27701:2025 can now be used as a standalone privacy information management standard. Here is what that means and how it relates to the DPDP Act and the GDPR.
In this article
ISO/IEC 27701 is the international standard for privacy information management. It helps organisations manage personal data in a structured, auditable way. The 2025 edition, published in 2025, brings an important change: it can now be used as a standalone privacy information management standard.
For companies that handle personal data across borders, including many Indian technology and services firms, this makes the standard easier to adopt. This guide explains what changed, who benefits and how the standard relates to laws such as India’s DPDP Act and the EU’s GDPR.
1. What changed in the 2025 edition
The earlier edition was built as an extension of ISO/IEC 27001. To use it, an organisation generally needed an information security management system in place first, and the privacy requirements were added on top. That suited companies that already held ISO 27001, but it was a barrier for organisations that wanted to start with privacy.
The 2025 edition can be used on its own. An organisation can build a privacy information management system without first implementing ISO 27001, although the two still work well together. This makes the standard more accessible to privacy teams, and it reflects how important privacy has become as a discipline in its own right.
| Question | Earlier edition | ISO/IEC 27701:2025 |
|---|---|---|
| Relationship to ISO 27001 | Built as an extension of it | Can be used as a standalone standard |
| Starting point | Usually an existing ISMS | Can start directly with privacy |
| Who it suits | Mainly ISO 27001 holders | Any organisation managing personal data |
| Use with ISO 27001 | Required in practice | Optional, and still a good fit |

2. Who benefits
Three groups gain most from the change. First, organisations that care mainly about privacy and do not yet hold ISO 27001. They can now adopt a recognised privacy framework directly, rather than building a full security management system first.
Second, organisations that process personal data on behalf of others, such as SaaS providers, outsourcing firms and service providers. Their customers increasingly ask how they protect personal data. A recognised privacy management system answers that question in a form procurement teams understand.
Third, organisations that already hold ISO 27001. They can still integrate the two, sharing risk methods, internal audits and management reviews. The standalone option simply gives more flexibility in how the systems are structured.
3. How it relates to the DPDP Act and the GDPR
ISO/IEC 27701 is not a law, and certification does not mean an organisation complies with any particular law. What it offers is a structure that supports legal compliance. It asks you to understand the personal data you process, define roles and responsibilities, assess privacy risks, put controls in place, respond to the rights of individuals and keep improving.
Those habits map well onto the core ideas of data protection laws in general terms. India’s Digital Personal Data Protection Act expects clear notices, valid consent or other lawful grounds, security safeguards, breach handling and responses to the rights of individuals. The GDPR has similar themes, with its own detailed rules. A well-run privacy information management system makes it easier to meet these duties and to show the evidence.
Use the standard as the backbone, then map each legal requirement onto it. Where a law sets a specific rule, such as a breach notification deadline or a particular notice requirement, record it as a requirement in your system and check that your controls meet it. Always confirm the exact legal text rather than relying on the standard alone.
A practical first step is a gap review against the standard. Start with your data inventory, your roles as controller or processor (Data Fiduciary or Data Processor under the DPDP Act) and your existing privacy controls. The gaps you find become your plan.
Plan who will run the system day to day. A privacy information management system needs an owner, a regular review rhythm and support from the teams that handle personal data. Without that, even a good design fades after the first audit.
