ISO 27701 Certification in UK

ISO 27701 certification addresses a specific accountability gap that exists between an organisation’s stated data protection policies and demonstrable compliance with UK GDPR obligations. The UK GDPR requires organisations to implement appropriate technical and organisational measures to protect personal data, but the regulation does not prescribe specific frameworks or controls. ISO 27701 fills this gap by providing a structured, internationally recognised framework whose implementation can be independently verified through third-party certification audit. For UK organisations subject to ICO enforcement, ISO 27701 certification provides objective evidence of a systematic approach to privacy management.

Regulatory Alignment with UK GDPR and the Data Protection Act 2018

The UK General Data Protection Regulation, as retained and amended by the Data Protection, Privacy and Electronic Communications (Amendments etc.) (EU Exit) Regulations 2019, establishes the primary data protection framework for UK organisations. ISO 27701 maps directly to key UK GDPR obligations, including the lawfulness of processing (Article 6), data subject rights (Articles 15–22), data protection by design and by default (Article 25), security of processing (Article 32), and records of processing activities (Article 30). The Annex mapping tables within ISO 27701 explicitly identify the correspondence between specific PIMS controls and GDPR provisions, enabling organisations to use the standard as a structured compliance tool.

For UK financial services organisations regulated by the Financial Conduct Authority (FCA) or the Prudential Regulation Authority (PRA), ISO 27701 certification complements existing regulatory obligations under SYSC (Senior Management Arrangements, Systems and Controls) and operational resilience requirements. The ICO has acknowledged the relevance of ISO 27701 in demonstrating accountability under the UK GDPR’s accountability principle (Article 5(2)), which requires controllers to be able to demonstrate compliance with the data protection principles. Third-party certification through CertPro’s licensed audit process provides an independent, documented record of compliance that meets the ICO’s accountability expectations.

ISO 27701 Certification in UK Financial Services and Fintech

UK financial services organisations and fintech firms process substantial volumes of personally identifiable information, including customer financial data, transaction records, credit information, and identity documents. ISO 27701 certification in the UK financial services sector provides a standardised mechanism for demonstrating to regulators, institutional clients, and counterparties that PII processing activities are governed by a certified management system. For fintech firms operating under FCA authorisation—including payment institutions, electronic money institutions, and regulated investment platforms—ISO 27701 certification supports compliance with both the UK GDPR and sector-specific FCA data protection expectations.

London’s position as a leading global financial centre means that many UK-based financial institutions process personal data across multiple jurisdictions, including EU member states where the EU GDPR applies. ISO 27701 certification conducted by CertPro addresses cross-border data transfer obligations, including the requirements of UK International Data Transfer Agreements (IDTAs) and Standard Contractual Clauses (SCCs) for transfers to third countries. Fintech companies processing open banking data under the Payment Services Regulations 2017 can use ISO 27701 certification to demonstrate compliance with the data protection conditions attached to third-party provider authorisation by the FCA.

ISO 27701 Compliance for UK Technology and SaaS Providers

UK technology companies and Software-as-a-Service (SaaS) providers frequently act as PII processors under the UK GDPR, processing personal data on behalf of their clients as data controllers. ISO 27701 certification is increasingly demanded by enterprise clients, public sector procurement frameworks, and institutional buyers as a condition of contract for technology suppliers processing personal data. The UK government’s Digital Marketplace and Crown Commercial Service procurement frameworks reference data protection standards including ISO 27701 as relevant certification for suppliers bidding on public sector contracts.

For SaaS providers headquartered in the UK but serving clients across the EU, ISO 27701 certification addresses the dual compliance burden of the UK GDPR and EU GDPR simultaneously. The certification demonstrates to EU-based controller clients that the UK SaaS processor operates a certified PIMS meeting equivalent data protection standards, which is relevant to the UK’s adequacy decision from the European Commission. Technology firms in sectors such as HR software, healthcare technology, legal technology, and marketing platforms process particularly sensitive categories of personal data and benefit from the specific controls addressing special category data processing within the ISO 27701 framework.

ISO 27701 certification requirements establish the specific obligations that UK organisations must satisfy to achieve and maintain certification. These requirements span documentation, governance, technical controls, and operational procedures across the full scope of the PIMS. Meeting ISO 27701 certification requirements demonstrates that an organisation has systematically addressed privacy risks, established accountable governance structures, and implemented controls proportionate to the nature and volume of PII processing activities. CertPro’s certification audit evaluates conformance with these requirements through document review, interviews, and technical testing.

ISO 27701 requires organisations to maintain documented information across several key areas of the PIMS. Mandatory documentation includes the PIMS scope statement, privacy policy, records of processing activities (RoPAs) as required under UK GDPR Article 30, data protection impact assessment (DPIA) procedures and completed assessments for high-risk processing, and documented privacy risk assessment and treatment processes. Organisations must also maintain documented procedures for handling data subject access requests (DSARs) and other data subject rights requests, as well as documented procedures for data breach notification in accordance with UK GDPR Articles 33 and 34.

The Statement of Applicability (SoA) required under ISO 27001 must be extended under ISO 27701 to include the additional privacy-specific controls from the standard’s Annexes B and C. The extended SoA must document which PIMS controls are applicable to the organisation’s role as a PII controller, PII processor, or both, with justification for any controls that have been excluded from scope. Maintaining comprehensive, accurate, and accessible documentation is essential for audit success; CertPro’s Stage 1 audit evaluates the completeness and suitability of documented information before the substantive Stage 2 conformance assessment proceeds.

ISO 27701 requires demonstrated top management commitment to the PIMS, including the assignment of specific privacy roles and responsibilities. UK organisations must designate a Data Protection Officer (DPO) where required under UK GDPR Article 37—mandatory for public authorities, organisations engaged in large-scale systematic monitoring, or those processing special category data at scale. Even where a DPO is not legally mandated, ISO 27701 requires clear assignment of responsibility for privacy management within the organisation’s governance structure. Top management must review the PIMS at planned intervals to ensure its continuing suitability, adequacy, and effectiveness.

ISO 27701 requires organisations to establish, implement, and maintain a privacy-specific risk assessment methodology that identifies risks to PII subjects—not just organisational risks—associated with processing activities. This PII-focused risk assessment extends the information security risk assessment required under ISO 27001, incorporating privacy-specific threat scenarios such as unauthorised disclosure, excessive data collection, unlawful purpose limitation, and inadequate data subject rights fulfilment. The risk treatment process must document selected controls, residual risks, and the rationale for treatment decisions, with evidence of management approval for the risk treatment plan.

Technical control requirements under ISO 27701 address the implementation of privacy-protective measures within information systems and processing environments. These include data minimisation controls ensuring only necessary PII is collected, pseudonymisation and encryption controls protecting PII at rest and in transit, access controls restricting PII access to authorised personnel on a need-to-know basis, and retention controls implementing defined retention periods with secure deletion procedures. For UK organisations processing biometric data, health data, or other special categories under UK GDPR Article 9, enhanced technical controls addressing the heightened risk profile of such data are required.

• ✓Documented PIMS scope statement aligned with actual PII processing activities
• ✓Extended Statement of Applicability covering ISO 27701 Annex B and Annex C controls
• ✓Records of Processing Activities (RoPAs) meeting UK GDPR Article 30 requirements
• ✓Privacy risk assessment and treatment documentation with management approval
• ✓Data Protection Impact Assessment (DPIA) procedures and completed assessments
• ✓Data subject rights fulfilment procedures (DSARs, erasure, rectification, portability)
• ✓Data breach notification procedures aligned with UK GDPR Articles 33 and 34
• ✓Third-party processor agreements incorporating UK GDPR Article 28 requirements
• ✓Staff privacy awareness training records and competency assessments
• ✓Internal audit programme covering PIMS controls and privacy obligations
• ✓Management review records demonstrating top-level PIMS oversight
• ✓Privacy by design and default procedures integrated into system development lifecycle

ISO 27701 draws a clear distinction between the obligations of PII controllers and PII processors, reflecting the corresponding distinction in the UK GDPR between data controllers and data processors. PII controller requirements, set out in Annex B of ISO 27701, address obligations including the identification of a lawful basis for processing, the provision of privacy notices to data subjects, the management of data subject rights, and the governance of third-party processors through appropriate contractual arrangements. UK organisations acting as controllers must demonstrate that each processing activity has a documented lawful basis under UK GDPR Article 6 (and Article 9 for special category data).

PII processor requirements, set out in Annex C of ISO 27701, address the specific obligations of organisations processing personal data on behalf of controllers. These include requirements to process PII only on documented instructions from the controller, to notify the controller of any security incidents affecting PII, to support the controller’s fulfilment of data subject rights requests, and to provide the controller with all information necessary to demonstrate compliance with Article 28 of the UK GDPR. Many UK technology companies, cloud service providers, and outsourced service providers act as both controllers and processors for different categories of processing, requiring them to implement controls from both Annex B and Annex C of ISO 27701.

ISO 27701 certification cost in the UK varies based on multiple organisational and audit-specific factors. Understanding the cost structure enables UK organisations to plan appropriately for certification investment and to evaluate the total cost of certification across the three-year certification cycle. ISO 27701 certification costs typically include audit fees for Stage 1, Stage 2, surveillance, and recertification audits, as well as internal costs associated with PIMS establishment, staff training, and documentation development. CertPro provides fixed-scope audit pricing based on defined organisational parameters, enabling accurate cost planning without variable or unexpected charges.

Factors Affecting ISO 27701 Certification Cost

The primary factors affecting ISO 27701 certification cost in the UK include organisational size (measured by number of employees and sites), complexity of PII processing activities, number of systems within scope, and whether the organisation is being certified as a PII controller, PII processor, or both. Organisations processing high volumes of sensitive or special category data typically require more extensive audit programmes, reflecting the increased complexity of their PIMS control environments. Multi-site organisations, including organisations with offices across multiple UK cities such as London, Manchester, Edinburgh, and Birmingham, require audit programmes that address privacy management consistency across all sites within scope.

The existing ISO 27001 certification status of an organisation significantly affects ISO 27701 audit cost. Organisations with a current, mature ISO 27001 certification require a smaller additional audit investment for ISO 27701 certification, as the ISMS controls are already assessed and the ISO 27701 audit focuses on the privacy-specific extension elements. Organisations pursuing ISO 27001 and ISO 27701 certification concurrently for the first time will incur a larger combined audit programme cost but benefit from integration efficiencies in audit planning and execution. CertPro offers integrated ISMS and PIMS audit programmes for organisations pursuing simultaneous certification.

Three-Year Certification Cycle Cost Planning

ISO 27701 certification cost planning must account for the full three-year certification cycle, including initial certification audit fees, annual surveillance audit fees in years one and two, and recertification audit fees in year three. Surveillance audit fees are typically 30–50% of the initial Stage 2 audit cost, reflecting the more focused scope of surveillance activities compared to the comprehensive initial conformance assessment. Organisations should also budget for internal costs including staff time for audit participation, corrective action implementation, and maintenance of PIMS documentation and records throughout the certification cycle.

For UK organisations using ISO 27701 certification to meet contractual requirements from enterprise clients or public sector procurement frameworks, the cost of certification should be evaluated against the commercial value of the contracts for which certification is a prerequisite. Many UK technology firms and service providers find that ISO 27701 certification directly enables access to enterprise and public sector contracts that would otherwise be unavailable, providing a measurable return on the certification investment. CertPro’s fixed audit pricing model enables accurate cost-benefit analysis without uncertainty about final audit costs.

ISO 27701 certification delivers measurable operational, commercial, and regulatory benefits for UK organisations that process personal data. The certification provides an internationally recognised credential that demonstrates systematic privacy management to regulators, clients, and counterparties. Beyond the certification credential itself, the process of implementing and maintaining a PIMS aligned with ISO 27701 requirements produces tangible improvements in an organisation’s data governance practices, privacy risk management capabilities, and operational resilience in the event of a data breach or regulatory investigation.

• ✓Provides independent, third-party evidence of UK GDPR and Data Protection Act 2018 compliance for ICO accountability purposes
• ✓Enables access to enterprise procurement frameworks requiring demonstrated privacy management certification
• ✓Strengthens contractual position with EU-based clients affected by UK-EU data transfer requirements
• ✓Reduces the risk of ICO enforcement action by demonstrating systematic approach to data protection
• ✓Supports cross-border data transfer compliance for organisations operating across UK and EU jurisdictions
• ✓Provides competitive differentiation in markets where privacy certification is a procurement differentiator
• ✓Establishes a documented, auditable record of privacy governance for regulatory submissions and due diligence
• ✓Integrates privacy management into existing ISO 27001 ISMS, reducing duplication of governance effort
• ✓Improves internal data governance through structured RoPA maintenance, DPIA procedures, and rights fulfilment processes
• ✓Demonstrates data protection accountability to data subjects, building trust in the organisation’s privacy practices

ISO 27701 certification reduces an organisation’s exposure to ICO enforcement action by demonstrating that privacy management is systematic, documented, and independently verified. The ICO’s enforcement policy acknowledges the relevance of certification and approved codes of conduct as factors demonstrating compliance accountability under the UK GDPR. In the event of a data breach or data subject complaint, an organisation with ISO 27701 certification can present its certified PIMS as evidence that appropriate technical and organisational measures were in place at the time of the incident, which is a relevant mitigating factor in ICO investigations and penalty determinations.

The ICO has the power to issue fines of up to £17.5 million or 4% of global annual turnover (whichever is higher) for serious infringements of the UK GDPR. For UK organisations processing significant volumes of personal data, the potential cost of enforcement action substantially exceeds the cost of ISO 27701 certification. Maintaining a certified PIMS with documented evidence of ongoing compliance activities provides a defensible record that can materially influence enforcement outcomes. The structured incident response and breach notification procedures required by ISO 27701 also ensure that organisations meet the 72-hour breach notification requirement to the ICO under UK GDPR Article 33.

ISO 27701 certification provides direct commercial advantages for UK organisations competing for enterprise and public sector contracts. The UK government’s procurement frameworks, including the Crown Commercial Service Digital Outcomes and Specialists framework and the G-Cloud marketplace, increasingly reference data protection certification requirements for suppliers processing personal data on behalf of public authorities. ISO 27701 certification provides a recognised credential that satisfies these procurement requirements, enabling certified organisations to bid for and win contracts that may be unavailable to non-certified competitors.

In the private sector, enterprise organisations in financial services, healthcare, and professional services increasingly require ISO 27701 certification from third-party suppliers processing personal data under data processing agreements. For UK technology firms, SaaS providers, and outsourced service providers, ISO 27701 certification reduces the length and complexity of supplier due diligence processes by providing an independently verified assessment of privacy management maturity. This accelerates the commercial relationship from initial procurement evaluation to contract execution, providing a measurable commercial benefit from certification investment.

• ✓Regulatory and Enforcement Risk Reduction
• ✓Commercial and Procurement Advantages

ISO 27701 certification addresses sector-specific data protection challenges faced by UK organisations across multiple industries. While the standard’s requirements are applicable to any organisation processing personally identifiable information, the practical implementation of PIMS controls varies significantly between sectors based on the nature of data processed, the regulatory environment, and the relationship between organisations and the data subjects whose information they process. CertPro’s audit methodology incorporates sector-specific risk considerations for UK financial services, technology, public sector, and healthcare organisations.

ISO 27701 in UK Public Sector Organisations

UK public sector organisations—including local authorities, NHS trusts, government departments, and arm’s-length bodies—process substantial volumes of sensitive personal data including health records, social care data, benefit entitlement data, and civil registration information. Public sector organisations are subject to the UK GDPR and the Data Protection Act 2018, with additional obligations under sector-specific legislation such as the Health and Social Care (Safety and Quality) Act 2015 and the NHS Data Security and Protection Toolkit requirements. ISO 27701 certification provides a structured framework that complements the NHS DSPT, enabling public sector bodies to demonstrate GDPR accountability through an independently certified management system.

Public authorities are required to appoint a Data Protection Officer under UK GDPR Article 37(1)(a), and ISO 27701 certification provides a structured framework for the DPO to oversee and evidence the organisation’s privacy management activities. The standard’s requirements for documented risk assessments, DPIA procedures, and internal audit programmes align closely with the expectations of the ICO’s accountability framework for public sector organisations. ISO 27701 certification can also support public sector organisations in demonstrating compliance with the Cabinet Office’s Government Functional Standard GovS 007 on Security and the National Cyber Security Centre’s Cyber Essentials requirements.

ISO 27701 for UK Healthcare and Life Sciences Organisations

Healthcare and life sciences organisations in the UK process health data, which constitutes special category data under UK GDPR Article 9, subject to enhanced processing restrictions and requiring explicit identification of a Schedule 1 condition under the Data Protection Act 2018 in addition to a UK GDPR Article 9 condition. ISO 27701 certification provides a framework for managing health data processing activities with the rigour required by both the ICO and sector-specific regulators including the Care Quality Commission (CQC) and the Medicines and Healthcare products Regulatory Agency (MHRA). Clinical research organisations and pharmaceutical companies processing patient data in clinical trials must also meet Good Clinical Practice (GCP) data governance standards, which ISO 27701 supports.

For private healthcare providers, medical technology companies, and digital health platforms operating in the UK, ISO 27701 certification signals to NHS commissioning bodies, private hospital groups, and insurance companies that health data is managed to a certified, audited standard. The integration of ISO 27701 PIMS controls with clinical information system security controls creates a unified governance framework that addresses both patient safety and data protection obligations. CertPro’s audit programme for healthcare sector organisations incorporates the specific control requirements applicable to special category data processing and the enhanced accountability obligations that apply to health data controllers.

ISO 27701 Certification in London and Major UK Business Centres

London’s status as a global technology, financial services, and professional services hub means that a disproportionate number of UK organisations requiring ISO 27701 certification are headquartered in or operate significant operations from the capital. London-based financial institutions, technology scale-ups, legal and professional services firms, and media organisations all process significant volumes of personal data and face demanding client and regulatory expectations regarding privacy management. ISO 27701 certification in London addresses the specific requirements of organisations operating in one of the world’s most concentrated business environments, where privacy management capability is frequently a condition of commercial relationships with major institutions.

Beyond London, UK technology hubs including Manchester, Edinburgh, Bristol, Cambridge, and Leeds are home to significant concentrations of technology and fintech organisations that require ISO 27701 certification to access enterprise markets. Manchester’s Northern Powerhouse digital economy, Edinburgh’s financial services and fintech cluster, and Cambridge’s life sciences and deep technology community each represent significant ISO 27701 certification demand from organisations seeking to demonstrate privacy management maturity to institutional clients, venture capital investors, and regulatory authorities. CertPro conducts ISO 27701 certification audits across all major UK business centres, with audit programmes structured to reflect the specific operational contexts of organisations in each location.

The relationship between ISO 27701 and UK GDPR compliance is direct and extensively documented within the standard itself. ISO 27701:2019 includes a normative Annex (Annex D) that maps each PIMS control to specific provisions of the EU GDPR, and this mapping is equally applicable to the UK GDPR given the substantial equivalence of the two regulatory frameworks following the UK’s implementation of the GDPR into domestic law through the Data Protection Act 2018. The mapping enables UK organisations to use ISO 27701 as a structured, auditable pathway to demonstrating compliance with the specific obligations imposed by the UK GDPR.

How ISO 27701 Maps to UK GDPR Obligations

UK GDPR Accountability Principle and ISO 27701 Certification

The accountability principle under UK GDPR Article 5(2) requires controllers to be able to demonstrate compliance with the data protection principles set out in Article 5(1). ISO 27701 certification directly addresses the accountability principle by providing an independently verified record of the organisation’s PIMS, demonstrating that data protection obligations are managed through a systematic, documented, and audited management system. The ICO’s guidance on accountability emphasises that organisations should be able to produce evidence of their compliance measures—ISO 27701 certification provides exactly this type of documented, third-party verified evidence.

For UK organisations that have received subject access requests, data subject complaints, or ICO enquiries, ISO 27701 certification provides a structured accountability record that demonstrates the organisation’s systematic approach to privacy management. The certification audit trail—including Stage 1 and Stage 2 audit reports, nonconformity records, corrective action documentation, and surveillance audit records—constitutes a comprehensive accountability record that can be presented to the ICO as evidence of compliance. This documented accountability trail is particularly valuable for organisations in sectors subject to high volumes of data subject requests, such as financial services, insurance, telecommunications, and retail.

Data Transfers and Cross-Border Processing

UK organisations that transfer personal data outside the UK must comply with Chapter V of the UK GDPR, which restricts transfers to countries that have not received a UK adequacy decision unless appropriate safeguards are in place. ISO 27701 certification supports cross-border data transfer compliance by demonstrating that the transferring organisation operates a certified PIMS that implements appropriate technical and organisational measures throughout the data lifecycle, including during transfer to third parties. For transfers to EU recipients, the UK’s adequacy decision from the European Commission (valid until June 2025, subject to review) enables transfers without additional safeguards, but ISO 27701 certification strengthens the accountability case for these transfers.

For UK organisations transferring data to countries without UK adequacy decisions—such as transfers to US-based cloud service providers or processors in emerging markets—ISO 27701 certification complements the use of International Data Transfer Agreements (IDTAs) or Standard Contractual Clauses (SCCs) by demonstrating that the UK exporter’s PIMS includes controls governing third-party processor oversight and cross-border transfer risk management. The ISO 27701 third-party management controls require certified organisations to assess the privacy practices of processors and sub-processors, review data processing agreements, and conduct periodic oversight activities—all of which are directly relevant to the Transfer Impact Assessment (TIA) requirements for restricted transfers under the UK GDPR.

CertPro is a Licensed CPA Firm that conducts ISO 27701 certification audits for UK organisations as an independent, accredited certification body. CertPro’s audit methodology is grounded in the requirements of ISO/IEC 27701:2019 and informed by the specific regulatory and operational context of UK data protection law. CertPro auditors possess demonstrated expertise in UK GDPR requirements, ISO 27001 ISMS architecture, and sector-specific privacy considerations across financial services, technology, public sector, and healthcare environments. The certification process is transparent, structured, and supported by clear audit programmes agreed with client organisations prior to audit commencement.

CertPro’s Audit Methodology and Independence

CertPro maintains strict auditor independence throughout the ISO 27701 certification process, ensuring that the certification decision is based solely on objective audit evidence and not influenced by any pre-existing relationship with the organisation being assessed. The certification decision is made by personnel independent of the audit team, in accordance with the impartiality requirements applicable to certification bodies. CertPro’s audit programmes are structured to address the specific risk profile and operational context of each organisation, with audit plans tailored to the scope, complexity, and processing activities of the UK organisation under assessment.

CertPro’s ISO 27701 audit methodology incorporates a risk-based sampling approach that prioritises audit attention on higher-risk processing activities, systems with significant PII volumes, and control areas with identified weaknesses. This approach ensures that the audit programme is proportionate to the organisation’s risk profile and produces a certification outcome that accurately reflects the effectiveness of the PIMS. Audit findings are documented with precision, referencing specific ISO 27701 requirements and the evidence examined, providing organisations with clear, actionable information about their PIMS conformance status.

Integrated ISO 27001 and ISO 27701 Certification Programmes

CertPro offers integrated audit programmes for UK organisations pursuing simultaneous ISO 27001 and ISO 27701 certification, enabling a unified audit process that assesses both the ISMS and the PIMS extension in a coordinated programme. Integrated audit programmes reduce the total audit burden for organisations by eliminating duplication in areas where ISO 27001 and ISO 27701 requirements overlap—such as risk assessment, internal audit, management review, and documented information management. The integrated programme produces two distinct certification outputs: an ISO 27001 certificate for the ISMS and an ISO 27701 certificate for the PIMS, each specifying their respective scopes.

For UK organisations already certified to ISO 27001:2022, the transition to ISO 27001:2022 must be completed before ISO 27701 certification can reference the current standard. The certification bodies have set a transition deadline of October 31, 2025, for organisations to migrate from ISO 27001:2013 to ISO 27001:2022. CertPro conducts ISO 27001:2022 transition audits as part of integrated audit programmes, enabling UK organisations to simultaneously update their ISMS certification and obtain ISO 27701 certification within a single coordinated audit cycle.

Sector Experience Across UK Industries

CertPro’s audit teams bring sector-specific experience to ISO 27701 certification engagements across the full range of UK industries subject to significant data protection obligations. In financial services, CertPro auditors understand the intersection of UK GDPR requirements with FCA and PRA regulatory expectations, the specific data protection considerations applicable to open banking and payment services, and the privacy requirements of investment management and insurance operations. This sector knowledge informs the audit programme design, ensuring that the certification assessment addresses the specific risk areas and control requirements relevant to each organisation’s industry context.

In the technology sector, CertPro’s auditors assess PIMS controls in cloud-based, multi-tenant, and distributed processing environments, evaluating the specific challenges of privacy management in software-as-a-service, platform-as-a-service, and infrastructure-as-a-service delivery models. For public sector organisations, CertPro’s audit programme incorporates the specific accountability requirements applicable to public authorities under the UK GDPR, including the mandatory DPO requirements and the enhanced obligations applicable to processing activities that carry high risks to data subjects’ rights and freedoms. This breadth of sector experience ensures that CertPro’s ISO 27701 certification audits are rigorous, contextually appropriate, and produce certification outcomes that are credible to regulators, clients, and counterparties.
