HIPAA vs CMMC: Two Mandates, Two Sectors
Both are mandatory in their fields, but they rarely apply to the same company. HIPAA governs protected health information in US healthcare and has no certificate. CMMC governs Controlled Unclassified Information in the US defense supply chain and requires a formal third-party certification. The deciding question is simple: what kind of data do you handle?
HIPAA vs CMMC (Level 2) at a Glance
A side-by-side look at how the two frameworks differ on purpose, cost, process, and recognition.
| HIPAA | CMMC (Level 2) | |
|---|---|---|
| Sector | US healthcare | US defense supply chain |
| Data protected | Protected Health Information (PHI) | Controlled Unclassified Information (CUI) |
| Proof | Risk assessment / audit (no cert) | C3PAO certification |
| Typical cost | $2,000–$50,000 risk assessment / audit | $30,000–$75,000 assessment; $138k–$285k all-in |
| Renewal | Ongoing; annual risk analysis expected | 3-yr cert + annual affirmations |
| Enforced by | HHS Office for Civil Rights | US Department of Defense |

How Much They Overlap
HIPAA vs CMMC (Level 2) FAQ
What is the difference between HIPAA and CMMC?
HIPAA is a US healthcare law protecting patient health information (PHI), enforced by HHS, with no certificate. CMMC is a US Department of Defense certification protecting Controlled Unclassified Information (CUI), assessed by a registered C3PAO. They apply to different sectors and different data, so they usually don't both apply to the same organization.
Is HIPAA or CMMC more expensive?
CMMC is far more expensive. A HIPAA risk assessment or audit runs $2,000–$50,000, while a CMMC Level 2 C3PAO assessment runs $30,000–$75,000 and total first-cycle certification averages $138,000–$285,000 with remediation included. HIPAA has no formal certification fee because there's no certificate.
Can a company need both HIPAA and CMMC?
It's uncommon but possible — for instance, a vendor that serves both a military health system (PHI) and broader DoD programs (CUI). In that case you'd run a HIPAA compliance program and pursue CMMC certification separately, though the overlapping technical safeguards reduce duplicated effort.
Does CMMC certification make me HIPAA compliant?
No. CMMC certifies your handling of defense CUI against NIST 800-171; it does not address HIPAA's Privacy Rule, Breach Notification Rule, or Business Associate Agreement obligations. If you handle PHI, you need a dedicated HIPAA program regardless of any CMMC status.
