GDPR Compliance Checklist

Why it matters

Conducting regular compliance reviews can substantially reduce exposure to regulatory penalties while reinforcing trust with data subjects. Working through this checklist gives you a structured way to verify adherence to core GDPR requirements across all areas of your operations.

Getting the groundwork right

Before you can demonstrate compliance, you need a comprehensive information audit that identifies all personal data being processed, documents data flows, and determines which individuals or teams have access to that information. Alongside this, you should have a clearly documented legal basis for all personal data processing activities, in accordance with Article 6 of the GDPR — for example consent, contractual necessity, legal obligation, vital interests, public task, or legitimate interests.

Transparency and design

You should publish a clear and accessible privacy policy that transparently informs data subjects about what personal data is collected, the purposes of processing, retention periods, and the legal basis for processing. You should also consistently implement the principle of 'data protection by design and by default' (Article 25), ensuring that privacy considerations are embedded into all systems, processes, and new projects from the outset.

Security and staff practice

Compliance depends on appropriate technical and organizational security measures, such as pseudonymization, anonymization, and encryption, to protect personal data against unauthorized access, alteration, or loss. This should be supported by an internal data protection policy that trains team members on security best practices, including email security, password hygiene, multi-factor authentication, device encryption, and secure VPN usage.

Risk, breaches, and accountability

You should establish a scheduled Data Protection Impact Assessment (DPIA) process to systematically identify, assess, and mitigate privacy risks associated with high-risk processing activities, and you should have a documented and tested breach response plan that ensures timely notification to the relevant supervisory authority (within 72 hours) and communication with affected data subjects in the event of a personal data breach. Accountability also means designating personnel responsible for monitoring and ensuring ongoing GDPR compliance across all departments, teams, and operational areas, executing formal Data Processing Agreements (DPAs) with all third-party vendors, processors, and service providers that handle personal data on your behalf, and appointing a qualified Data Protection Officer (DPO) where required under Article 37 of the GDPR — that is, if you are a public authority, engage in large-scale systematic monitoring, or process large volumes of special category data.

Data subject rights

You need workable processes for each of the rights the regulation grants. Provide an accessible and efficient way for data subjects to exercise their Right of Access (Article 15) by requesting and receiving a copy of all personal data you hold about them. Give them a straightforward mechanism to exercise their Right to Rectification (Article 16), allowing them to correct, update, or complete any inaccurate or incomplete personal data. Have a clear procedure for the Right to Erasure (Article 17), enabling them to request deletion of their personal data when it is no longer necessary or when consent has been withdrawn. And put processes in place to honor the right to object to processing (Article 21) and to request restriction of processing (Article 18) in applicable circumstances. No procedure is complete unless people can use it without difficulty and track their request.

Frequently Asked Questions

The checklist covers the core GDPR areas you need to evidence: knowing what personal data you process, having a lawful basis and a transparent privacy notice, embedding data protection by design and by default, applying technical and organizational security measures such as pseudonymization, anonymization and encryption, training staff on security practices, running data protection impact assessments for high-risk processing, and maintaining a tested breach response plan. It also covers accountability and governance — accountable personnel, data processing agreements with vendors, and appointing a data protection officer where Article 37 requires one — and the data subject rights of access, rectification, erasure, objection and restriction.

Work through the assessment section first to record administrative details such as the date it was conducted, who prepared it, and the location. Then work through each substantive section, answering every question Yes, No or N/A against what you can actually demonstrate rather than what you intend to do. Where the answer is No, treat it as a gap: note who owns the fix and by when. Once remediation is under way, repeat the review on a regular schedule and record the signature, the completion time, and the actual start and end dates.

No. The checklist questions are framed around specific GDPR provisions — Article 6 on lawful basis, Article 25 on data protection by design and by default, Article 37 on appointing a data protection officer, and Articles 15 to 21 on data subject rights — and the breach response question refers to notifying the relevant supervisory authority within 72 hours. Beyond those references, you still need to satisfy the regulation and any other law that applies to you.

Store completed reviews as evidence of your compliance efforts, and revisit unanswered or negative items at each subsequent review. The completed form can show how you assessed your alignment with EU data protection regulations, what gaps you identified, and how you responded.
