GDPR and HIPAA: key differences and similarities
GDPR and HIPAA both aim to protect sensitive information, but they operate in different legal systems with distinct definitions, rights, and enforcement. Health tech and SaaS vendors serving EU patients and US covered entities often need both.

Key takeaways
- GDPR is broad EU privacy law for personal data; HIPAA is US law focused on PHI held by covered entities and business associates.
- Health data is often special category under GDPR Article 9, triggering extra conditions.
- HIPAA uses BAAs; GDPR uses DPAs under Article 28—contracts differ but vendor governance overlaps.
- Meeting one framework does not automatically satisfy the other.
This guide covers:
- Territorial and material scope of each regime
- Overlapping security and accountability themes
- Major legal and operational differences
- Practical dual-compliance approach

Scope and territorial reach
| Aspect | GDPR | HIPAA |
|---|---|---|
| Geography | EU/EEA residents’ data; extraterritorial reach | US HIPAA-covered entities and business associates |
| Data types | Personal data broadly | PHI tied to covered entities/associates |
| Regulator | EU/EEA supervisory authorities | HHS OCR (and state AGs for breaches in some cases) |
| Sector | Cross-industry | Healthcare and related services |
A US telehealth app with EU users may face GDPR for EU personal data and HIPAA for US PHI simultaneously.
Key similarities
- Security expectations — risk-based safeguards (GDPR Article 32; HIPAA Security Rule).
- Vendor accountability — written agreements, flow-down duties, breach notification chains.
- Breach notification — timelines and documentation (72-hour authority notice under GDPR; HIPAA has specific timing and content rules).
- Minimum necessary — GDPR data minimization parallels HIPAA’s minimum necessary standard.
- Training and policies — workforce awareness and documented procedures.
Shared control libraries (access management, encryption, logging) support both programs when mapped carefully.
Key differences
| Topic | GDPR | HIPAA |
|---|---|---|
| Lawful basis / permitted uses | Article 6 + Article 9 conditions | Privacy Rule permitted uses and disclosures |
| Individual rights | Broad DSAR rights (access, erasure, portability, etc.) | HIPAA access/amendment/accounting rules—different scope |
| Consent | Strict GDPR consent standard for optional processing | HIPAA authorization for specific disclosures—not identical |
| Penalties | Up to €20M / 4% global turnover | OCR civil money penalties; state laws may add |
| Certification | No EU GDPR certificate | No HIPAA “certification” from HHS—third-party audits optional |
| Marketing | ePrivacy + GDPR rules | HIPAA marketing restrictions on PHI |
GDPR right to erasure may conflict with HIPAA record retention requirements—legal analysis required for dual-regulated records.
Operating under both frameworks
- Data map — separate PHI vs EU personal data flows; identify overlap (EU health data).
- Unified control set — map HIPAA Security Rule safeguards to GDPR Article 32 evidence.
- Contract stack — BAA + DPA for vendors processing both PHI and EU personal data.
- Notices — GDPR privacy notice + HIPAA Notice of Privacy Practices where applicable.
- Incident playbooks — single triage, dual notification decision trees.
- RoPA + HIPAA documentation — align retention and destruction schedules.

FAQ
Does HIPAA compliance mean we are GDPR compliant?
No. HIPAA does not address all GDPR transparency, transfer, and rights requirements for EU personal data.
Is PHI always special category data under GDPR?
Health data is generally special category under Article 9, requiring an additional condition beyond Article 6.
Can we use one global privacy notice?
Healthcare organizations often maintain separate or layered notices for HIPAA NPP and GDPR transparency requirements.
