What is Data Subject Access Request?

DSARs are a cornerstone of data subject rights under GDPR and similar privacy regulations. When an individual submits a DSAR, the organization must provide a copy of all personal data being processed, the purposes of processing, the categories of data involved, recipients or categories of recipients, retention periods, and the source of data if not collected directly from the individual. Organizations must also inform data subjects of their rights to rectification, erasure, restriction of processing, and the right to lodge a complaint with a supervisory authority. Handling DSARs efficiently requires knowing where personal data resides across all systems — a challenge for organizations with fragmented data architectures. Best practices include implementing a DSAR intake portal, maintaining a data inventory or Record of Processing Activities (ROPA), automating data discovery across databases and SaaS tools, and training customer-facing staff to recognize and escalate DSARs appropriately.
