SGS Thailand BlogSeptember 14, 2026
Personal data is now one of the most sensitive and valuable assets an organization manages. Customers, employees, business partners, and regulators increasingly expect organizations to handle personal data responsibly, transparently, and securely.
Having a privacy policy is no longer enough. Organizations need to show that privacy is managed through a clear system, with defined responsibilities, risk controls, documented evidence, and continual improvement.
This is where ISO/IEC 27701 becomes highly relevant.
ISO/IEC 27701 is an international standard for a Privacy Information Management System, also known as PIMS. The latest version, ISO/IEC 27701:2025, sets requirements and provides guidance for establishing, implementing, maintaining, and continually improving a PIMS.
Why ISO/IEC 27701 matters
Organizations today collect and process personal data across many business activities, including sales, human resources, customer service, marketing, digital platforms, supply chains, and third-party services.
This creates privacy risks such as:
- Collecting more personal data than necessary
- Using personal data for unclear purposes
- Giving access to people who do not need it
- Losing control over data shared with vendors
- Failing to define responsibilities clearly
- Being unable to show evidence of privacy controls
- Facing trust issues after a data breach
ISO/IEC 27701 helps organizations manage these risks in a structured way. It helps turn privacy from a policy statement into an operating system for governance, accountability, controls, and improvement.
According to ISO, ISO/IEC 27701 helps strengthen data privacy and protection capabilities, supports compliance with privacy regulations such as PDPA and GDPR, builds trust with partners, clients and regulators, aligns with ISO/IEC 27001, and facilitates evidence-based privacy management.
How ISO/IEC 27701 connects with ISO/IEC 27001
ISO/IEC 27001 focuses on information security management. ISO/IEC 27701 focuses on privacy information management.
In simple terms:
- ISO/IEC 27001 helps protect information.
- ISO/IEC 27701 helps manage personal data and privacy.
Together, they help organizations strengthen both Data Security and Data Privacy.
ISO confirms that ISO/IEC 27701 aligns with existing ISO/IEC 27001 systems to streamline implementation. The earlier ISO/IEC 27701:2019 version was described as an extension to ISO/IEC 27001 and ISO/IEC 27002 for privacy information management, before being replaced by the 2025 version.
For organizations that already have ISO/IEC 27001, ISO/IEC 27701 can be a practical next step to extend information security governance into privacy governance.
Who should consider ISO/IEC 27701?
ISO states that ISO/IEC 27701 is suitable for any organization that collects, processes, stores, or controls personally identifiable information, including public, private, and not-for-profit organizations.
It is especially relevant for organizations that:
- Handle customer, employee, user, patient, member, or partner data
- Operate digital platforms, applications, or online services
- Work with cloud providers, outsourced service providers, or data processors
- Need to strengthen PDPA or GDPR readiness
- Want to build trust with enterprise clients or international partners
- Already have ISO/IEC 27001 and want to add privacy governance
- Need a clearer framework for privacy risk and accountability
Recommended target audiences include:
- CIOs, CISOs, CTOs, and IT leaders
- Data Protection Officers
- Legal and compliance teams
- Cybersecurity and IT security teams
- ISO management system owners
- Digital transformation project managers
- Quality, risk, and governance managers
- Senior leaders responsible for customer trust and business resilience
Business benefits of ISO/IEC 27701
- Builds trust with customers and partners
Customers and business partners want confidence that personal data is handled responsibly. ISO/IEC 27701 helps organizations demonstrate that privacy is managed through a structured and recognized system.
- Supports privacy risk management
The standard helps organizations identify, assess, and manage privacy risks related to the collection, use, storage, transfer, and processing of personal data.
- Strengthens governance and accountability
ISO/IEC 27701 helps organizations define privacy roles, responsibilities, controls, and evidence. This supports clearer ownership and better decision-making.
- Supports regulatory readiness
ISO states that ISO/IEC 27701 supports compliance with global privacy regulations such as GDPR. In Thailand, organizations can use the standard to support a more structured approach to personal data management under PDPA, while still seeking appropriate legal guidance for specific compliance obligations.
- Integrates with existing information security systems
Organizations with ISO/IEC 27001 can use ISO/IEC 27701 to extend their information security management system into privacy management.
How to start implementing ISO/IEC 27701
Organizations should not start with documents only. They should start by understanding their personal data, privacy risks, and current control gaps.
A practical starting roadmap includes:
- Identify what personal data the organization collects, uses, stores, shares, or deletes.
- Clarify whether the organization acts as a data controller, data processor, or both.
- Review current policies, procedures, contracts, and technical controls.
- Compare the current system against ISO/IEC 27701 requirements.
- Integrate privacy controls with existing information security controls.
- Define roles, responsibilities, and process owners.
- Train employees on privacy awareness and handling personal data.
- Review third-party and vendor privacy obligations.
- Conduct internal audits and management reviews.
- Improve the system continuously based on risks, incidents, and business changes.
5 common mistakes when starting ISO/IEC 27701
- Treating privacy as a legal task only Privacy involves legal, IT, HR, operations, business development, marketing, procurement, and leadership teams.
- Having a policy but no operating evidence A privacy policy is useful, but organizations also need evidence that controls are implemented, reviewed, and improved.
- Not clarifying controller and processor roles Unclear roles can create confusion in contracts, responsibilities, data handling, and accountability.
- Separating privacy from information security Privacy and security are closely connected. Personal data cannot be managed responsibly without proper security controls.
- Ignoring third-party privacy risks Cloud providers, outsourced IT providers, agencies, consultants, and other vendors may process personal data. Organizations need appropriate oversight and control.
ISO/IEC 27701 as a business advantage
Privacy is no longer only about avoiding penalties. It is about trust.
Organizations that can demonstrate responsible data handling may be better positioned in business negotiations, supplier qualification, enterprise customer requirements, and digital trust conversations.
Conclusion
ISO/IEC 27701 provides a structured way for organizations to manage personal data, strengthen privacy governance, and demonstrate accountability. It is especially valuable for organizations handling sensitive or large volumes of personal data, working with third parties, or seeking stronger alignment with privacy expectations such as PDPA and GDPR.
For organizations that want to move beyond a privacy policy and build a practical privacy management system, ISO/IEC 27701 offers a clear and internationally recognized framework.
A good starting point is to assess current privacy practices, identify gaps, and build a practical roadmap that connects Data Security, Data Privacy, risk management, and business trust.
