ISO 27701 Requirements Explained: How to Enhance Your Privacy Framework

Privacy is becoming more closely connected to cybersecurity. It makes sense: you can’t govern how data is used if you can’t secure it first. This connection has become impossible to ignore, and more and more regulations like GDPR, CCPA, and LGPD demand accountability for both the security and the privacy of the data you control or manage. 

Yet, managing privacy isn’t straightforward. Different countries, different rules, and different expectations from customers and regulators make it a fragmented landscape. For global organizations, this creates one big question: How do we create a consistent, scalable way to manage privacy risks?

Recognizing this, ISO 27701 was developed as a global privacy standard that helps organizations bridge the gap between cybersecurity and privacy compliance. As the International Association of Privacy Professionals (IAPP) describes, it provides “distinctive guidance for establishing, implementing, maintaining and continually improving a privacy information management system for controllers and processors of personal data.” In other words, ISO 27701 meets the growing demand for a framework that integrates privacy governance directly into ISO 27001’s widely adopted information security management system (ISMS)—without reinventing the wheel.

What is ISO 27701?

ISO 27701, officially titled “Security techniques — Extension to ISO/IEC 27001 and 27002 for privacy information management,” is an international standard published in 2019. It extends the well-known ISO 27001 information security framework to include privacy-specific controls and guidance for managing PII.

If there’s nothing else you come out of this blog with, know this: ISO 27701 is not a typo of someone meaning to type “ISO 27001”. But it is closely connected to it. It’s an extension that builds upon ISO 27001 with the goal of integrating privacy into your existing ISMS.

ISO 27701’s Purpose:

• Helps organizations manage privacy risks.
• Provides guidance for both PII controllers and PII processors.
• Maps privacy controls to global regulations like GDPR, CCPA, and others.

This dual focus on security and privacy reflects the reality that data protection isn’t possible without solid cybersecurity foundations.

What is a Privacy Framework, Anyway?

A privacy framework is a structured approach to managing how an organization collects, processes, stores, and shares personal data. It ensures that privacy risks are identified, mitigated, and continuously managed. 

Three Types of Privacy Frameworks:

• Law-specific frameworks: These are tied directly to specific regulations, like GDPR in Europe or CCPA in California. They’re built to ensure you meet the legal requirements in that jurisdiction.
• Industry-neutral frameworks: These frameworks, like the NIST Privacy Framework, offer flexible, risk-based guidance that can be applied across different industries. They aren’t tied to any single regulation but help organizations manage privacy risks according to their own unique environment.
• Integrated cybersecurity-privacy frameworks: This is where ISO 27701 comes in. Instead of starting from scratch, it builds on existing cybersecurity systems—specifically ISO 27001—and adds privacy controls, creating a seamless connection between securing data and governing its use.

ISO 27701 Requirements: The Essentials

The ISO 27701 certification requirements focus on integrating privacy management into your existing information security management system (ISMS). Here’s a clearer breakdown of what’s involved so you know exactly where to start:

1. ISO 27001 Certification as a Prerequisite

• You must already be certified in ISO 27001 (or implement it in parallel with ISO 27701).

ISO 27001 provides the foundation for information security, and ISO 27701 builds on this to address privacy.

2. Privacy Information Management System (PIMS)

• Establish a PIMS within your ISMS designed to manage personally identifiable information (PII).
• Identify and define the roles your organization plays: PII controller, PII processor, or both.
• Outline responsibilities, including how you handle data subject rights, breach notifications, and privacy risk assessments.

3. ISO 27701 Controls: What’s New?

ISO 27701 introduces 49 additional controls:

• 31 controls for PII controllers (organizations that determine the purpose and means of processing PII).
• 18 controls for PII processors (organizations that process PII on behalf of a controller).
• These are layered on top of the ISO 27002 security controls, expanding them to include privacy-specific objectives.

For example:

• A security control requiring access management under ISO 27001 is expanded to include privacy considerations—like limiting access to PII based on necessity.
• Incident response plans under ISO 27001 are extended to cover privacy breaches and regulatory reporting obligations.

4. Mapping to Privacy Laws: How It Helps

• ISO 27701 includes annexes mapping its controls to privacy regulations like GDPR and CCPA.

This helps organizations understand how their PIMS aligns with global legal requirements, although certification itself doesn’t guarantee compliance with these laws.

Instead, ISO 27701 provides a structured approach to documenting, monitoring, and improving your privacy practices.

5. Examples of ISO 27701 Controls: Key Privacy Functions

These controls go beyond cybersecurity into privacy-specific activities:

• Data Protection Impact Assessments (DPIAs): Ensure that privacy risks are identified and mitigated when new projects or systems process PII.
• Transparency and Communication: Define how you inform data subjects about how their data is collected, used, and stored.
• Managing Third-Party Processors: Apply due diligence and oversight to vendors handling PII.
• Handling Data Subject Rights: Establish processes for responding to data subject requests (access, correction, deletion, portability).
• Consent Management: Maintain records of consent where applicable and ensure mechanisms are in place to withdraw consent.

These controls often overlap with ISO 27701 cyber security best practices—such as access control, encryption, and breach management—but they’re refined to address privacy nuances.

By integrating these requirements, ISO 27701 helps organizations align their security and privacy efforts, creating a unified framework for protecting PII while meeting diverse regulatory expectations.

ISO 27701 Certification: Steps to Get Certified

1. Baseline with ISO 27001

Ensure your organization has an ISO 27001-certified ISMS. If not, implement it alongside ISO 27701.

2. Conduct a Privacy Gap Assessment

Evaluate your current privacy practices against ISO 27701 requirements. Identify gaps where controls or processes are missing.

3. Implement PIMS Controls

Deploy privacy-specific controls based on your role as a PII controller, processor, or both.

4. Train Your Team

Educate staff on privacy risks, data protection obligations, and compliance processes.

5. Internal Audit and Review

Assess your PIMS and ISMS to ensure readiness for audit and certification.

6. Engage a Certification Body

Work with an accredited certification body to audit and certify your ISO 27701 compliance.

ISO 27701 vs Other Privacy Frameworks: Do You Need More?

This is where things get interesting. ISO 27701 integrates privacy with cybersecurity, but it isn’t the only option. Depending on your regulatory landscape, you might need additional privacy frameworks.

Organizations in highly regulated sectors (e.g., healthcare, finance) or in regions with stringent data protection laws (like the EU) often layer multiple frameworks to cover all bases. While ISO 27701 provides strong foundational privacy controls and integrates with ISO 27001, it doesn’t dictate how to handle specific privacy outcomes or maturity levels.

ISO 27701 vs NIST Privacy Framework:

• ISO 27701 is certifiable and globally recognized, ideal for organizations needing external validation through audits. It’s tightly bound to ISO 27001, making it a strong fit for businesses already focused on cybersecurity and looking to extend into privacy.
• NIST Privacy Framework (PF) is a flexible, risk-based model. It isn’t certifiable but offers guidance on managing privacy risks across different tiers of organizational maturity. It enables companies, especially U.S.-based ones, to tailor privacy programs without the structural overhead of an ISMS.

The key distinction is that ISO 27701 is prescriptive and certifiable, while NIST PF is adaptable and focused on outcomes. This means NIST allows more flexibility in defining what “good privacy management” looks like, whereas ISO 27701 offers a structured pathway tied to globally recognized security practices.

For U.S.-centric companies or those in dynamic industries (like tech or healthcare), NIST PF is often favored for its adaptability. Yet, pairing it with ISO 27701 gives organizations a balanced approach: the certifiable rigor of ISO and the flexible governance of NIST.

ISO 27701 vs GDPR-Specific Frameworks (e.g., BS 10012):

• BS 10012 is a GDPR-centric privacy framework designed as a standalone Personal Information Management System (PIMS). It is well-suited for UK and EU organizations focused solely on GDPR compliance, without the need for a broader ISMS.
• ISO 27701 supports GDPR compliance, but it’s designed to scale globally across multiple privacy regimes. It doesn’t embed specific regulatory timelines (like GDPR’s 72-hour breach notification rule) but provides a structured framework that maps to various laws.

The choice between the two hinges on your scope:

• If you’re operating primarily in the EU or UK and need a streamlined GDPR compliance approach, BS 10012 could suffice.
• If you’re managing global data flows and need to balance cybersecurity with privacy, ISO 27701 offers broader flexibility with international recognition.

Some organizations adopt both, using ISO 27701 as the overarching privacy and security framework and BS 10012 as a GDPR-specific layer.

Should U.S. Organizations Rely on ISO 27701 Alone?

While ISO 27701 privacy controls map to laws like GDPR and CCPA, U.S. companies may face sector-specific requirements. Many adopt ISO 27701 alongside the NIST Privacy Framework to cover both bases: formal certification (ISO) and flexible risk management (NIST).

Common Misconceptions About ISO 27701

1. It’s a Standalone Privacy Framework:

False. It’s an extension of ISO 27001.

2. ISO 27701 Guarantees Legal Compliance:

Not exactly. It provides a framework to manage privacy risks, but regulators judge compliance against laws, not standards.

3. It’s Only for GDPR:

Incorrect. ISO 27701 controls are jurisdiction-neutral and can be mapped to multiple privacy laws globally.

Should You Pursue ISO 27701 Certification?

If you’re already ISO 27001 certified, ISO 27701 is a natural next step to bolster your privacy framework. It offers international recognition, aligns cybersecurity with privacy, and provides assurance to stakeholders. But it may not cover every regulatory nuance.

For many U.S. organizations, combining ISO 27701 with flexible tools like the NIST Privacy Framework offers the best of both worlds: certification and risk management.
