GDPR Compliance Audit

When You Need a GDPR Audit

A GDPR audit is typically commissioned in the following situations:

• Periodic Accountability Review: Article 24 requires controllers to review and update their compliance measures; an independent audit provides documented evidence that this obligation is met.
• Customer and Enterprise Due Diligence: Controllers increasingly audit their processors, and enterprise customers request independent evidence of GDPR compliance before signing data processing agreements.
• New Products, Markets, or Processing Activities: Launching products, entering the EU/EEA market, deploying AI features, or changing data flows introduces new obligations that should be verified before go-live.
• Post-Incident or Pre-Regulator Assurance: After a personal data breach, a complaint, or ahead of expected supervisory authority attention, an audit establishes the factual compliance position.
• Mergers, Acquisitions, and Investment: Data protection compliance is a standard due diligence item; an independent audit report answers it directly.
• DPO and Management Support: An external audit gives the DPO and management an independent view that internal reporting alone cannot provide.

What We Assess

The audit criteria are tailored to the organization’s role and processing activities. Assessment areas are grouped around the structure of the Regulation:

• Governance and Accountability (Articles 5(2), 24, 37–39): Data protection policies, assigned responsibilities, DPO designation and position where applicable, management oversight, training, and documented evidence of compliance measures.
• Lawfulness, Fairness, and Transparency (Articles 5–9, 12–14): Lawful bases for each processing activity, conditions for special categories, consent records and withdrawal mechanisms, and the content, timing, and accessibility of privacy notices.
• Data Subject Rights (Articles 15–22): Procedures, response records, timelines, and identity verification supporting access, rectification, erasure, restriction, portability, and objection requests.
• Records and Data Lifecycle (Articles 5(1)(c)–(e), 25, 30): Records of processing activities verified against actual operations, data minimization, retention schedules and their enforcement, and data protection by design and by default in systems and processes.
• Risk and Impact Assessment (Articles 35–36): DPIA methodology, completed assessments for high-risk processing, and prior consultation arrangements where applicable.
• Processors and Third Parties (Article 28): Data processing agreements, sub-processor authorization and oversight, and data sharing arrangements.
• International Transfers (Chapter V): Transfer mapping, adequacy reliance, standard contractual clauses, transfer impact assessments, and supplementary measures where applicable.
• Security and Breach Handling (Articles 32–34): Technical and organizational measures appropriate to the risk, breach detection and escalation procedures, the breach register, notifications to supervisory authorities, and communication to data subjects.

Audit Process

• 1. Scoping and Planning: We define the audit scope — legal entities, business functions, systems, and processing activities — confirm the organization’s role for each activity, agree the audit criteria, and plan interviews, evidence requirements, and the sampling approach.
• 2. Evidence Collection: We review accountability documentation, interview process and control owners, sample operational records (rights requests, breach records, DPIAs, DPAs, consent records), and verify implemented technical and organizational measures against documented practice.
• 3. Analysis and Findings: Each finding is evaluated against the applicable GDPR obligation, classified as conformity, nonconformity, or observation, supported by objective evidence, and prioritized by regulatory exposure and impact on data subjects.
• 4. Reporting and Closing Meeting: Results are consolidated into a formal audit report and presented to management, including key findings, the reasoning behind them, and recommended prioritization. Where agreed, a follow-up review verifies the closure of findings after remediation.

Deliverables

• GDPR Compliance Audit Report: A formal report documenting the audit scope, criteria, methodology, evidence reviewed, findings with article-level mapping, and an independent audit conclusion.
• Compliance Matrix: An obligation-by-obligation view of the assessed GDPR requirements showing conformity status and supporting evidence for each.
• Prioritized Findings Register: Nonconformities and observations with the applicable obligation, objective evidence, affected process, and priority — usable directly as a remediation backlog.
• Executive Summary: A management-level summary of the overall compliance position, key risks, and recommended focus areas, suitable for boards, customers, and due diligence requests.
• Closing Meeting and Follow-Up Review: Presentation of results to management and, where agreed, verification of remediation with an updated report.

Basis of Work

The audit is performed against agreed data protection, information security, regulatory, and organizational criteria to ensure a consistent, impartial, and evidence-based audit approach.

• Regulation (EU) 2016/679: General Data Protection Regulation.
• Applicable National Data Protection Legislation: National implementing and supplementary requirements included in the agreed audit scope.
• EDPB Guidelines and Opinions: Relevant European Data Protection Board guidance applicable to the audited processing activities.
• ISO/IEC 27001:2022 / ISO/IEC 27002:2022: Referenced as supporting criteria for evaluating technical and organizational security measures.
• Applicable Internal Policies and Procedures: Organizational governance documents, data protection procedures, records, and supporting control framework documentation.
• Contractual Requirements: Applicable controller, processor, customer, and data sharing requirements included in the agreed audit scope.

The audit report reflects the results of evidence reviewed during the engagement and is limited to the defined audit scope, agreed criteria, audit sampling, and information made available at the time of the audit.

This engagement does not include consulting, implementation, control design, policy drafting, or legal advice, and does not constitute certification, a supervisory authority approval, or a legal opinion. The audit results are intended to provide an independent assessment of compliance against the agreed criteria.
