GDPR Data Subject Rights: How to Stay Compliant
GDPR grants individuals eight enforceable rights over their personal data, and regulators are increasingly judging organizations on whether their systems can actually execute those rights—not whether their policies describe them.
Key takeaways
- GDPR grants individuals eight enforceable rights over their personal data. Fulfilling them is an infrastructure requirement.
- Each right translates into a concrete system-level operation: locate the data, act on it within a defined timeline, propagate that action across every system that holds it, and document every step.
- Organizations that fulfill rights reliably are those with the infrastructure to do so. Process documents and manual workflows cannot scale to the volume, complexity, or speed that compliance demands.
- Lethe, Ethyca's automated DSR execution engine, manages the underlying infrastructure for request intake, multi-system execution, verification, and audit-ready documentation with minimal manual effort.
In December 2024, the Irish Data Protection Commission fined Meta €251 million following inquiries into a 2018 data breach affecting approximately 29 million Facebook accounts globally.
What are data subject rights under GDPR?
GDPR data subject rights are enforceable legal rights that give individuals within the European Economic Area control over how organizations collect, use, store, and share their personal data. These rights apply to customers, employees, website visitors, app users, and any identifiable individual whose data is processed.
The eight GDPR data subject rights
Right to be informed (Articles 13 and 14)
This right requires organizations to explain how personal data is collected and used before or at the point of collection.
Right of access (Article 15)
Article 15 gives individuals the right to confirm whether their data is being processed and to receive a copy along with details about processing purposes.
Right to rectification (Article 16)
Article 16 requires organizations to correct inaccurate personal data and complete incomplete records without undue delay.
Right to erasure (Article 17)
Applies when data is no longer necessary, consent is withdrawn, processing is unlawful, or an objection overrides the organization’s legal basis for processing.
Right to restrict processing (Article 18)
Allows individuals to restrict processing when data accuracy is contested.
Right to data portability (Article 20)
Gives individuals the right to receive their personal data in a structured, commonly used, machine-readable format.
Right to object (Article 21)
Creates rules for direct marketing and legitimate-interest processing.
Rights related to automated decision-making (Article 22)
Gives individuals the right not to be subject to decisions based solely on automated processing that produce legal or similarly significant effects.
How enforcement exposes operational weaknesses
Enforcement actions repeatedly highlight operational gaps:
- Incomplete access responses
- Missed response deadlines
- Failure to notify third parties of erasure
- Unenforced processing restrictions
Best practices for managing data subject rights at scale
Managing data subject rights at scale requires more than documented policies. Organizations need systems that can execute requests consistently.
Automate request workflows
Automated workflows reduce delays by identifying request types, locating relevant systems, triggering actions, and generating responses consistently across requests.
Maintain a live view of personal data
Continuous data discovery helps organizations track where personal data resides.
Embed privacy controls into systems
Privacy controls must operate inside the systems processing data.
Monitor and audit all actions
Organizations must be able to demonstrate how requests were fulfilled. Audit logs should record queried systems, executed actions, and response timelines to support accountability.
