GDPR-Compliant SaaS Development Checklist

If you serve EU users, GDPR compliance should be built into product delivery from day one, not patched later.

Product and Data Foundations

  • Define lawful basis for each data flow.
  • Map all personal data fields and processing purposes.
  • Minimize data collection to necessary scope.
  • Set retention windows with deletion policies.

Engineering Controls

  • Encrypt data in transit and at rest.
  • Enforce role-based access controls.
  • Keep immutable audit logs for key actions.
  • Use secure secret management and key rotation.

User Rights Workflows

  • Data access request flow
  • Data correction flow
  • Data export flow
  • Data deletion flow
  • Consent withdrawal flow (where applicable)

Vendor and Infrastructure Controls

  • Maintain Data Processing Agreements with vendors.
  • Review sub-processor list and data residency.
  • Confirm backup and restore controls.
  • Validate incident response and breach notification process.

Release Gate Before Go-Live

  1. Privacy policy is published and linked.
  2. Terms and legal basis are documented.
  3. Logging and alerting are active.
  4. Access controls are validated in staging.
  5. Data subject request runbook is tested.
