GDPR and ISO Standards – How Do ISO Standards Support Compliance with Data Protection Regulations?

Data protection is one of the biggest challenges facing modern organizations. The introduction of GDPR (General Data Protection Regulation) across the European Union has forced companies to adhere to high data protection standards. Proper management of personal data is not only a legal obligation but also a key element in building trust among customers and business partners.

ISO standards are a set of international management guidelines that support companies in effectively implementing systematic solutions, including those related to personal data protection. Their application helps to streamline processes, enhance the security of information and personal data, and meet regulatory requirements in a more comprehensive and efficient manner.

GDPR – Key Obligations for Companies

GDPR (General Data Protection Regulation) is an EU regulation introduced to protect the personal data of EU citizens. These regulations apply to all organizations processing personal data of individuals within the EU, regardless of their location.

The main obligations under GDPR include:

• Implementing a risk-based approach: Adopting strategies based on risk analysis.
• Informing data subjects: Notifying individuals about the processing of their personal data.
• Establishing and properly documenting internal policies: Creating internal policies for managing the data protection system.
• Securing data against breaches: Implementing measures to protect data from unauthorized access or leaks.
• Fulfilling the rights of data subjects: Ensuring rights such as the right to erasure (the "right to be forgotten") or the right to access personal data are upheld.
• Implementing appropriate technical and organizational measures: Putting in place the necessary safeguards to protect processed data.

GDPR is not merely a collection of legal requirements – it also represents a change in the approach to handling personal data.

“GDPR introduces a culture of conscious information management, including personal data, within organizations.”

– emphasizes Attorney Tomasz Osiej, President of the Board at Omni modo.

How Do ISO Standards Support Data Protection?

ISO standards, developed by the International Organization for Standardization, represent a collection of best management practices that can help organizations meet GDPR requirements.

In the context of personal data protection, the following standards are particularly important:

• ISO 9001 – a quality management standard that enables the standardization of processes and documentation, providing a solid foundation for the implementation of further ISO standards.
• ISO 27001 – a standard focused on information security management, covering the identification and minimization of risks related to data.
• ISO 27701 – an extension of ISO 27001 dedicated to personal data protection and adapted to the requirements of privacy regulations.

Implementing these standards helps companies effectively manage risk, protect personal data, and fulfill their legal obligations. The adoption of ISO standards not only supports regulatory compliance but also increases the maturity of an organization’s information management and data security practices.

Mandatory Nature of GDPR vs. Voluntary Nature of ISO – Key Differences

GDPR is a fundamental legal instrument whose implementation is mandatory for all organizations processing the personal data of EU citizens. Violations of GDPR can result in heavy financial penalties – up to 20 million euros or 4% of a company’s global annual turnover.

On the other hand, ISO standards are voluntary; however, they are highly regarded worldwide as a benchmark for high-quality management. ISO 27701, as a standard dedicated to data protection, provides tools that support compliance with privacy regulations.

As Łukasz Kowalski, Managing Director of Certiget, emphasizes: 

“ISO standards are collections of best practices that – when properly implemented – help build lasting resilience and an effective organizational culture.”

Which ISO Standard Should You Choose for Your Organization?

The choice of the appropriate ISO standard depends on the nature of your organization’s activities and its specific needs. If the goal is to streamline processes and improve management, starting with ISO 9001 is advisable—a universal standard that can serve as the foundation for further enhancements.

Companies handling sensitive information, such as personal data or trade secrets, should consider implementing ISO 27001, which offers comprehensive information security management. For organizations that require advanced protection of personal data—especially when collaborating with international partners—the optimal solution is to combine ISO 27001 with ISO 27701. It is important to note that ISO 27701 certification is only available for organizations that already hold an ISO 27001 certificate.

When choosing an ISO standard and implementing a management system, the involvement of experts knowledgeable in both ISO standards and GDPR regulations is crucial. Partnering with experienced advisors, such as Omni Modo, ensures that both aspects are addressed with the necessary diligence, thereby minimizing the risk of non-compliance.

As Łukasz Kowalski, Managing Director of Certiget, points out:

“A lack of a comprehensive approach among consultants often leads to problems with ensuring GDPR compliance. Therefore, it is worth choosing partners who not only understand the requirements of ISO standards but also grasp the applicable legal regulations in the industry.”

 

ISO Certification – Confirmation of Compliance and Quality

ISO standards, used by organizations to build management systems, are typically subject to certification. This process is carried out by independent auditors from certification bodies and concludes with the awarding of an ISO certificate, which formally confirms compliance with the specific standard’s requirements. The certificate is valid for three years, during which the organization must undergo surveillance audits to verify the ongoing compliance and effectiveness of the implemented processes.

Importantly, a certification audit is not a punitive control but rather an independent assessment of the management system. Its goal is not only to confirm compliance but also to identify areas for improvement. Implementing and certifying ISO standards increases the trust of customers, business partners, and regulators, and in some industries, it is even a prerequisite for cooperation.

ISO 27701 certification, as an extension of ISO 27001, underscores a high level of personal data protection—especially important for organizations processing large amounts of data or operating in regulated sectors such as finance, healthcare, or e-commerce.

The choice of a certification body, just like selecting a consultant to support the implementation of an ISO standard, should be a well-informed decision. Experience, accreditation, and approach to certification are key factors – reputable certification bodies stand out for their reliability, objectivity, and high standards. Their primary role is to independently assess compliance with standards; however, the way an audit is conducted can influence how an organization identifies potential areas for further development.

Certification bodies can be divided into global, international, and local, with or without accreditation. At Certiget, you will find the Catalog of ISO Certification Bodies from around the world. Click to search for a partner that suits your needs, or simply contact Certiget directly

Summary

ISO standards provide indispensable support in meeting GDPR requirements. They facilitate the implementation of effective data protection processes, enhance customer trust, and minimize the risk of data breaches. Additionally, they can help organizations demonstrate compliance with GDPR, for example during regulatory inspections.

Collaborating with experts who combine knowledge of ISO standards and GDPR regulations is essential for successfully implementing management systems that ensure compliance with both legal regulations and best practices in data protection.
