As global data privacy regulations evolve, organizations are increasingly turning to ISO/IEC 27701 as a unified and internationally applicable framework to manage privacy risks and ensure legal compliance. Unlike laws such as the GDPR, which are geographically limited, ISO/IEC 27701 serves as a universal privacy management system that organizations of all sizes and industries can adopt.
This article explores how to apply ISO/IEC 27701 in real-world contexts, focusing on how organizations can use it to meet their obligations as data controllers and data processors.
Why Context Matters in Applying Privacy Standards
Every organization handles personal data differently depending on its size, industry, and jurisdiction. While legal frameworks like the GDPR specify what must be done to protect personal data, ISO/IEC 27701 provides the how—offering detailed operational guidance applicable globally.
Instead of juggling multiple regional laws, organizations can streamline compliance through ISO/IEC 27701 by embedding privacy within their existing Information Security Management Systems (ISMS).
Understanding Roles: Data Controllers vs. Data Processors
One of the central distinctions in ISO/IEC 27701—and in most data protection laws—is between:
- Data Controllers: Organizations that determine the purpose and means of processing personal data.
- Data Processors: Entities that process data on behalf of a controller, following their instructions.
This separation is critical because ISO/IEC 27701 assigns different responsibilities and accountability measures to each.

What Is a Privacy Information Management System (PIMS)?
At the heart of ISO/IEC 27701 is the PIMS (Privacy Information Management System)—an extension of ISO/IEC 27001. It is designed to help organizations protect personally identifiable information (PII) and meet global privacy expectations.
Examples of PII include:
- Names, dates of birth, and ID numbers
- Email addresses and phone numbers
- IP addresses, device IDs, and location data
To apply a PIMS, organizations must assess what PII they collect, how it’s stored, how it’s processed, and what mechanisms are in place to protect it.
Implementing ISO/IEC 27701: Key Steps
✅ 1. Assess Your Context
- What PII do you handle?
- Are you a data controller, data processor, or both?
- What legal jurisdictions apply to your operations?
✅ 2. Establish Privacy Governance
- Define internal policies and assign privacy roles.
- Establish training programs for staff who handle sensitive data.
- Create privacy notices that are transparent and compliant.
✅ 3. Build the PIMS Framework
- Use ISO/IEC 27701 to extend your ISO/IEC 27001 system.
- Incorporate controls from ISO/IEC 27002 as part of your privacy plan.
- Identify risks related to PII and establish mitigation strategies.
✅ 4. Fulfill Controller and Processor Responsibilities
If you are a Data Controller:
- Create privacy notices and inform individuals of their rights
- Enable subject access requests (DSARs) and data deletion options
- Ensure privacy by design and by default is embedded in systems
If you are a Data Processor:
- Follow only the instructions given by the controller
- Assist with DSARs as needed
- Notify stakeholders of cross-border data transfers

Real-World Example: Controller-Processor Relationship
Imagine a company, Erin Ltd, outsources its payroll processing to a third-party provider.
- Erin Ltd is the Data Controller: They decide who gets paid and how much.
- The payroll provider is the Data Processor: They execute the payments and store employee data.
Under ISO/IEC 27701:
- Erin Ltd must maintain privacy notices, provide access to personal data, and ensure lawful processing.
- The processor must only act on Erin Ltd’s instructions and help with any privacy-related requests.
Final Thoughts
Applying ISO/IEC 27701 effectively requires more than technical controls—it demands a context-aware, governance-first approach. By understanding your organization’s role, the data it handles, and the applicable privacy obligations, you can create a privacy-resilient infrastructure that meets international standards.
Whether you’re a startup managing user profiles or a multinational dealing with cross-border data flows, ISO/IEC 27701 offers a scalable and universal approach to data privacy management.
