SOC 2 vs HIPAA
Side-by-side comparison of SOC 2 attestation and HIPAA Security Rule obligations — what each requires, overlap, and why one does not replace the other.
Key differences
| Dimension | SOC 2 | HIPAA |
|---|---|---|
| Governing body | AICPA — Trust Services Criteria examined by a licensed CPA firm | HHS / OCR — HIPAA Security Rule and related Privacy/Breach Notification Rules under 45 CFR Part 160/164 |
| Nature of obligation | Customer- and contract-driven attestation — not a general US statutory duty for most SaaS | Legal regime for covered entities and business associates handling PHI/ePHI — BAAs and Security Rule decisions are mandatory when in scope |
| Output | SOC 2 Type I/II report (restricted use) describing controls and CPA opinion | No single “HIPAA certificate” equivalent to SOC 2 — compliance is demonstrated through policies, BAAs, risk analysis, and safeguard implementation (Required vs Addressable) |
| Scope trigger | Buyer questionnaires and contracts asking for a recent report | Whether you create, receive, maintain, or transmit PHI as a covered entity or business associate |
| Control style | Principles-based criteria (CC1–CC9 plus optional categories) you design and evidence | Administrative, physical, and technical safeguards with Required and Addressable specifications you must implement, document equivalents for, or document why neither is reasonable |
| Typical SaaS sequencing | Default US B2B trust artifact once procurement blocks deals | Must run in parallel whenever PHI is in scope — do not wait for a SOC 2 report before Security Rule work |
| Public signal | Report shared under NDA / trust portal | Often evidenced via BAAs, security whitepapers, and questionnaire answers — not a public HIPAA “cert badge” |
| Failure mode | Qualified opinion, sample exceptions, lost deals | OCR investigation, breach notification duties, contractual liability under BAAs |
Control overlap
Access control, audit logging, transmission security, integrity protections, and incident response appear in both SOC 2 (especially CC6/CC7) and HIPAA technical/administrative safeguards. Teams can share IdP MFA, encryption, and monitoring evidence — but HIPAA still needs Required vs Addressable documentation, risk analysis, and BAAs. A clean SOC 2 Type II does not prove HIPAA compliance, and HIPAA safeguards do not produce a SOC 2 report.
Sequencing advice
If you handle PHI as a BA or covered entity, implement HIPAA Security Rule foundations immediately (risk analysis, access, audit controls, transmission security, BAAs). Add SOC 2 Security Type II when US enterprise buyers require an attestation. Use /tools/framework-selector for sequencing heuristics and /frameworks/hipaa plus /frameworks/soc-2 for hub depth. Map shared technical measures once; keep legal accountability separate.
