SOC 2 and HIPAA serve different purposes and aren't interchangeable. Here's when healthtech companies need one, the other, or both.
SOC 2 and HIPAA are not competing frameworks — they address different audiences and serve different legal purposes. HIPAA is a U.S. federal law with mandatory requirements for covered entities and their business associates. SOC 2 is a voluntary attestation framework published by the AICPA that enterprise buyers use as a proxy for security maturity. A healthcare SaaS company can be fully HIPAA-compliant and still fail a SOC 2 audit, and vice versa. Most healthtech vendors eventually need both.
What each framework actually covers
HIPAA — specifically the Security Rule (45 CFR Part 164, Subpart C) — governs the protection of electronic protected health information (ePHI). It mandates specific administrative, physical, and technical safeguards. Compliance is not audited in the same sense as SOC 2: HHS OCR enforcement typically follows a breach investigation rather than a proactive audit. Business Associates must sign a BAA before receiving ePHI and are directly liable under the HIPAA Omnibus Rule.
SOC 2 covers the Trust Services Criteria (TSC) defined by the AICPA: Security (CC series), Availability (A series), Confidentiality (C series), Processing Integrity (PI series), and Privacy (P series). The Security TSC is the default scope; others are added based on customer requirements. A SOC 2 audit is performed by a licensed CPA firm and produces a written attestation report that buyers can review.
Where the frameworks overlap
Access controls: Both require role-based access management, least-privilege principles, and terminated-employee deprovisioning procedures.
Encryption: HIPAA requires encryption for ePHI in transit and at rest (addressable specification); SOC 2 Security TSC CC6.1 requires encryption of data in transit and production systems.
Audit logging: HIPAA requires activity logs for systems accessing ePHI; SOC 2 CC7.2 requires logging and monitoring of security events.
Incident response: HIPAA's Breach Notification Rule requires documented incident response and 60-day breach notification to HHS; SOC 2 CC7.3–7.5 require incident response procedures and communication.
Risk management: HIPAA's Risk Analysis requirement (§164.308(a)(1)) maps closely to SOC 2's CC3 series (risk assessment and risk management).
When SOC 2 alone is sufficient
If your healthtech product doesn't handle ePHI — for example, a wellness app that doesn't integrate with EHR systems, a B2B analytics product processing de-identified data, or a care coordination tool that only handles aggregate population data — HIPAA may not apply. Enterprise buyers in this category will ask for SOC 2, not a BAA.
Even if you handle some health-adjacent data, whether it qualifies as ePHI under the HIPAA Privacy Rule (45 CFR §164.514) depends on whether it's individually identifiable and maintained by a covered entity or business associate. Legal counsel should make this determination — don't self-certify out of HIPAA scope based on a blog post.
The dual-compliance program for healthtech vendors
Start with SOC 2 Type I: Gets you through early enterprise sales cycles in 8–12 weeks. Most health system IT security teams will accept a Type I during initial vendor evaluation.
Execute BAA agreements: Required before onboarding any customer that qualifies as a covered entity. A BAA is a contract obligation, not an audit artifact — you can do this in parallel with your SOC 2 program.
Build toward SOC 2 Type II with Privacy TSC: If you process ePHI, adding the Privacy TSC to your SOC 2 scope demonstrates that your privacy controls have been independently tested — an argument that goes beyond a self-assessed BAA.
Consider HITRUST CSF at Series B+: Health systems above a certain size (particularly IDNs and academic medical centers) require HITRUST over SOC 2. HITRUST is built on HIPAA controls plus additional controls and is significantly more expensive ($50K–$150K) and time-intensive. It is not a first-program framework for startups.
Choosing an auditor with dual SOC 2/HIPAA experience
Not all SOC 2 auditors have deep HIPAA experience. When evaluating auditors for a combined program, ask specifically: how many healthtech clients do they serve, do they include HIPAA mapping notes in their SOC 2 reports, and have they performed BAA reviews as part of vendor risk engagements? Firms with documented health data experience include Prescient Assurance, BARR Advisory, A-LIGN, and Johanson Group. For combined programs, budget $25K–$60K for the first cycle depending on scope and firm.
Common questions from healthtech buyers
Enterprise health IT teams ask several questions that SOC 2 alone doesn't answer. Knowing how to respond to these is as important as having the report.
'Do you have a signed BAA on file with all your subprocessors who touch ePHI?' — This is a HIPAA operational question. The answer should be yes, with a current list available. Your GRC platform's vendor inventory should track BAA status.
'What is your breach notification timeline?' — HIPAA Breach Notification Rule requires notification to HHS and affected individuals within 60 days of discovery. Your incident response policy should state this explicitly. SOC 2 CC7.4 covers incident notification, but HIPAA notification specifics belong in your HIPAA policies.
'How do you handle patient data deletion requests?' — This is a HIPAA Privacy Rule right of access question. If your system stores ePHI, you need a documented procedure for responding to deletion or access requests from covered entities on behalf of their patients.
'Do you conduct annual HIPAA risk assessments?' — The HIPAA Security Rule §164.308(a)(1) requires a periodic technical and non-technical evaluation. A SOC 2 risk assessment overlaps substantially but doesn't fully substitute. Document your HIPAA risk assessment separately.
