What is GDPR?
The General Data Protection Regulation (GDPR) is a European Union regulation that protects the personal data and privacy of individuals in the EU/EEA. It requires organizations to minimize data collection, provide transparency, and give individuals control over their data. Our module supports GDPR with IP anonymization (enabled by default), no third-party data transfers, consent management, and audit logging.
What is HIPAA?
The Health Insurance Portability and Accountability Act (HIPAA) is a US federal law that protects sensitive patient health information (PHI). It requires access controls, audit trails, data integrity, and transmission security. Our module supports HIPAA with role-based access control, two-factor authentication, complete audit logs, and secure document delivery.
PDF Embed & SEO Optimize provides technical controls that support GDPR and HIPAA compliance. Compliance responsibility remains with your organization.
