Best HIPAA Compliance Auditors: 33 Firms Compared

There is no government-issued HIPAA certification — what buyers and partners actually accept is an independent assessment or attestation from a credible firm. The 33 firms below have HIPAA work on record; compare their profiles and typical engagement signals.

How this list is ranked (as of August 17, 2026): independent verification status first, then relevance to this page, then profile completeness (credentials, pricing and timeline transparency, platform integrations), then verified client reviews. Ranking placement cannot be bought and firms do not pay to be listed. Independent verification of the directory is in progress — until a firm is verified, its data is compiled from public records and labeled accordingly. Full details: how we verify auditors.

What to check before hiring a HIPAA assessor

Assessment vs. attestation

Decide whether you need a gap assessment, a Security Rule risk analysis, or a formal attestation (often SOC 2 + HIPAA mapping) — firms package these differently.

Healthcare data experience

An assessor who has worked with PHI pipelines, BAAs, and de-identification will scope faster and miss less.

SOC 2 + HIPAA in one pass

Many health-tech companies satisfy both customer security reviews and HIPAA expectations with a combined engagement.

Risk analysis rigor

OCR enforcement consistently cites missing or shallow risk analyses — ask exactly how the firm documents yours.

Frequently asked questions

Is there an official HIPAA certification?

No. The U.S. government does not certify HIPAA compliance. Organizations demonstrate compliance through documented risk analyses and independent third-party assessments or attestations — which is what the firms on this page provide.

Do I need a CPA firm for HIPAA?

Not necessarily — HIPAA assessments are not CPA attestations. But if you want HIPAA mapped into a SOC 2 report (common for health-tech vendors), that combined report must come from a licensed CPA firm.

How were these HIPAA firms ranked?

By verification status, then profile completeness, then verified client reviews — never by payment. See the methodology page for every signal used.
