ISO/IEC 27701 vs 27001: What’s the Real Difference?

 

Introduction

As organisations increasingly prioritise data protection and privacy, understanding the difference between ISO/IEC 27701:2019 and ISO/IEC 27001:2022 certifications has become essential. Both standards are internationally recognised and linked to information security, but they serve distinct purposes. This guide explains how each certification supports organisational goals and why choosing the right one matters in today’s compliance landscape.

What ISO/IEC 27001:2022 Certification Focuses On?

  • ISO/IEC 27001:2022 is the global benchmark for establishing, implementing and maintaining an Information Security Management System (ISMS) — addressing risk, controls and information-security practices.

  • It guides organisations in protecting data, systems and networks from security threats, breaches or unauthorised access.

  • The standard emphasises risk-based thinking, leadership commitment, performance evaluation and continual improvement within the ISMS.

What ISO/IEC 27701:2019 Certification Focuses On?

  • ISO/IEC 27701:2019 builds on ISO/IEC 27001 by extending the Information Security Management System to a Privacy Information Management System (PIMS).

  • It provides specific requirements and guidance for managing personal data and privacy controls, helping organisations demonstrate accountability and compliance with privacy expectations.

  • It helps govern consent management, data processing activities, privacy risk assessments, breach response mechanisms and privacy-related documentation.

Key Differences Between the Two Certifications

🔹 Scope of Focus

  • ISO/IEC 27001:2022 centres on information security risks and cybersecurity controls.

  • ISO/IEC 27701:2019 expands that focus to include privacy controls and personal data governance.

🔹 Applicable Areas

  • ISO/IEC 27001 applies broadly to confidentiality, integrity and availability of information.

  • ISO/IEC 27701 adds privacy concepts such as data subject rights, consent management and privacy impact assessments.

🔹 Regulatory Alignment

  • ISO/IEC 27001 supports compliance with cybersecurity regulations and corporate risk frameworks.

  • ISO/IEC 27701 aligns closely with privacy regulations and expectations such as GDPR, data protection laws and organisational privacy policies.

🔹 Certification Outcomes

  • ISO/IEC 27001 results in an ISMS certification, demonstrating robust information-security management.

  • ISO/IEC 27701 leads to a PIMS certification that signifies structured privacy management integrated with the organisation’s ISMS.

Why Both Matter in Today’s Environment?

  • Cybersecurity and privacy governance have become intertwined in modern operations — with data breaches and privacy violations carrying financial, legal and reputational consequences.

  • Organisations that demonstrate both strong information-security controls and robust privacy practices stand out to customers, partners and regulators alike.

  • Choosing the right certification — or combining both — can help manage risk comprehensively and support compliance with multiple regulatory frameworks.

ISO for NGOs & Nonprofits: Proving Impact, Credibility & Governance

Image
Nonprofits and NGOs operate in a space where accountability, trust, and measurable impact define success. Donors, governments, and communities expect transparency, proper fund use, ethical governance, and evidence of results. ISO certifications can provide organizations in this sector with recognized systems that strengthen credibility, governance, and donor confidence. Why ISO Certifications Matter for NGOs & Nonprofits? Many NGOs face skepticism over how funds are used, whether programs deliver promised outcomes, and whether governance is robust. An ISO certification offers independent validation that processes are documented, risks are identified and handled, and internal controls are in place. For many international donors, certification is becoming a part of due diligence — helping NGOs win funding, partnerships, and legitimacy. Relevant ISO Standards for NGOs & Nonprofits Some standards that commonly benefit NGOs include: ISO 9001 for quality management, helping imp...

How to Identify and Address ISO 9001 Non-Conformities

In the world of quality management, adherence to ISO 9001 standards is a critical aspect for businesses striving for excellence. ISO 9001:2015 sets out the criteria for a quality management system and is based on a number of quality management principles including a strong customer focus, the motivation and implication of top management, the process approach, and continual improvement.

ISO certifications in East Germany (German Democratic Republic) and how Pacific Certifications can help

Image
  The German Democratic Republic (GDR), commonly known as East Germany, existed from 1949 until German reunification in 1990. During its existence, East Germany had its own standards organization, the Amt für Standardisierung, Messwesen und Warenprüfung (ASMW), which was responsible for setting national standards. While the ISO (International Organization for Standardization) develops and publishes international standards, individual countries choose how and whether to adopt these standards within their national framework. Since East Germany was a separate entity until 1990, it has interacted with ISO standards differently compared to how modern Germany does today. Post-reunification, Germany has fully integrated into the international standards system, with the Deutsches Institut für Normung (DIN) being the primary national standards body in Germany. DIN is a member of ISO and plays a significant role in the development and adoption of ISO standards within Germany. ISO Standards a...
