The DSAR Challenge

Under GDPR Article 15, individuals have the right to obtain confirmation of whether their personal data is being processed, and to access that data. Organizations must respond within one calendar month.

For organizations processing data across multiple systems, this can be a significant operational challenge.

Building an Automated DSAR Workflow

1. Intake & Identity Verification

  • Provide a clear submission channel (web form, email, in-app)
  • Verify the requester's identity without collecting excessive data
  • Log the request with a timestamp for deadline tracking

2. Automated Data Discovery

  • Map all systems containing personal data
  • Build automated queries to extract data by identifier
  • Include backups and archived data in your scope
  • Check third-party processors and sub-processors

3. Data Compilation & Review

  • Aggregate data from all sources into a unified format
  • Redact third-party personal data
  • Flag any exemptions (e.g., trade secrets, legal privilege)
  • Generate a human-readable report

4. Secure Delivery

  • Use encrypted channels for data delivery
  • Provide data in a commonly used, machine-readable format
  • Document the response for compliance records

Key Metrics to Track

  • Average response time — Target well under 30 days
  • Completion rate — Percentage of DSARs fully resolved
  • Data source coverage — Percentage of systems automated
  • Requester satisfaction — Follow-up survey results

Tools & Platforms

Modern GDPR platforms like PrivacyForge automate much of this workflow:

  • Centralized DSAR intake and tracking
  • Automated data discovery across connected systems
  • Built-in identity verification workflows
  • Deadline monitoring with alerts
  • Audit-ready response documentation
