SOC 2 vs HIPAA: Clause-by-Clause Comparison

SOC 2 Trust Services Criteria is industry standard and applies to Service organizations storing customer data. Type II reports prove operating effectiveness over a 6-12 month window. De-facto requirement for SaaS vendors selling to US mid-market and enterprise buyers. HIPAA Privacy + Security Rules is sectoral and applies to Covered entities (providers, plans, clearinghouses) and business associates handling protected health information (PHI). Sectoral US law; binds any AI vendor that touches PHI. The practical tension is that why a SOC 2 report does not make an AI system HIPAA compliant, and what the gap actually consists of. They are not substitutes. Across the fifteen governance dimensions compared here, 12 are addressed substantively by both, 0 are materially stronger in SOC 2, and 0 are materially stronger in HIPAA. Treating either as a superset of the other is the most common and most expensive mistake.

SOC 2 Trust Services Criteria Type: Industry standard. Jurisdiction: United States (de-facto international). In force: Continuously updated (2017 TSC + 2022 points of focus). Exposure for getting it wrong: No statutory penalty; failed audit blocks customer procurement. Best suited to: SaaS vendors needing a sales-unblocking, customer-trusted attestation HIPAA Privacy + Security Rules Type: Sectoral. Jurisdiction: United States (healthcare). In force: Privacy Rule 2003; Security Rule 2005; HITECH 2009. Exposure for getting it wrong: USD 137 to USD 2,067,813 per violation; criminal up to 10 years (45 CFR 160.404, 42 USC 1320d-6). Best suited to: US healthcare providers, plans, clearinghouses, and any vendor processing PHI The penalty asymmetry is usually what decides sequencing. Both carry real consequences, so the question is which applies to your jurisdiction and data first.

These are the dimensions both frameworks address substantively, which means one piece of evidence can often satisfy both. This is where a combined programme saves real effort rather than just feeling tidy. Governance + accountability. SOC 2 (CC1.1-CC1.5): CC1.1-CC1.5 require commitment to integrity, board oversight, structure / authority, competence, and accountability. HIPAA (45 CFR 164.308(a)(2); 164.530(a)): 164.308(a)(2) requires assigned Security Official; 164.530(a) requires Privacy Official and contact person. Risk management process. SOC 2 (CC3.1-CC3.4): CC3.1-CC3.4 require risk identification, fraud risk, change in environment, and risk-response selection. HIPAA (45 CFR 164.308(a)(1)): 164.308(a)(1)(ii) requires a Risk Analysis and Risk Management process. Data handling + minimisation. SOC 2 (C1.1-C1.2; P1-P8 (Privacy)): Confidentiality criteria C1.1-C1.2 cover identification, retention, destruction; Privacy criteria address PII; AI-specific data sourcing not explicit. HIPAA (45 CFR 164.502(b); 164.514): 164.502(b) minimum necessary; 164.514(d) standards; 164.514(b) de-identification; restrictions on training-data use. Transparency + disclosure. SOC 2 (CC2.1-CC2.3; P1.1): CC2.1-CC2.3 require communication of objectives and quality information; Privacy P1.1 requires notice. No AI disclosure obligation. HIPAA (45 CFR 164.520): 164.520 requires a Notice of Privacy Practices; no AI disclosure obligation, but FDA guidance applies to clinical AI. Post-market monitoring + drift. SOC 2 (CC4.1-CC4.2): CC4.1-CC4.2 require ongoing and separate evaluation, and communication of deficiencies. HIPAA (45 CFR 164.308(a)(1)(ii)(D)): 164.308(a)(1)(ii)(D) requires Information System Activity Review; periodic, not continuous. Incident + serious-incident reporting. SOC 2 (CC7.3-CC7.5): CC7.3-CC7.5 require incident-management process: detection, response, evaluation, communication, recovery. HIPAA (45 CFR 164.308(a)(6); 164.400-414): 164.308(a)(6) requires security-incident procedures; 164.400s require breach notification to HHS within 60 days. The caveat worth stating: overlapping subject matter does not mean interchangeable evidence. SOC 2 and HIPAA frequently want the same control documented to a different standard of proof, so plan to write once and format twice.

Worth knowing before you assume a compliance programme equals a control programme. Neither SOC 2 nor HIPAA addresses the following substantively: Model lifecycle controls. Whether design, testing, validation, deployment, and retirement of AI models is governed. Human oversight + intervention. Whether human-in-the-loop, contestability, or human review of automated decisions is required. Bias + fairness testing. Whether bias audits, fairness metrics, or disparate-impact testing are required. These are not oversights so much as scope boundaries. They still have to be handled by someone, and in practice that falls to the platform layer rather than the framework.

Neither framework outranks the other on obligation, so sequence by exposure. Work out which applies to your jurisdiction, your data and your customers first, and start there. SOC 2 is in force from Continuously updated (2017 TSC + 2022 points of focus); HIPAA from Privacy Rule 2003; Security Rule 2005; HITECH 2009. In most organisations the deciding factor is commercial rather than legal: whichever one a buyer is already asking for in procurement is the one to complete first, because it unblocks revenue while the other unblocks risk.

Areebi does not certify you against either framework. What it does is produce the runtime evidence both of them ask for, from the same control plane, so the overlap above becomes real rather than theoretical. For SOC 2: CC6.1-CC6.8 access + encryption satisfied by SSO + BYOK + per-tenant network isolation. CC7.3-CC7.5 incident workflow satisfied by alerting and audit-log evidence. CC9.2 vendor risk supported by built-in AI vendor scorecard exports. Continuous control monitoring outputs Type II evidence directly. For HIPAA: PHI-aware DLP blocks unauthorised disclosures; BAA signed with hosting provider. 164.312(b) audit controls satisfied by immutable, 6-year-retainable audit log. Per-user access controls with break-glass workflow for 164.312(a) requirements. Encryption at rest and in transit (164.312(a)(2)(iv) addressable) on by default. The common thread is that both frameworks want to know what your AI systems actually did, not what your policy said they should do. That is an operational logging and enforcement problem before it is a documentation problem.
