Framework Comparison

SOC 2 vs CMMC: Which Applies to You?

SOC 2 is a commercial, voluntary security attestation that proves your controls to private-sector buyers. CMMC is a mandatory US Department of Defense certification required to handle Controlled Unclassified Information (CUI). If you sell to the DoD, CMMC isn't optional; if you sell to commercial enterprises, SOC 2 is the norm.

SOC 2 vs CMMC (Level 2) at a Glance

A side-by-side look at how the two frameworks differ on purpose, cost, process, and recognition.

	SOC 2	CMMC (Level 2)
Driver	Commercial / voluntary	US DoD mandate
Assessor	Licensed CPA firm	Registered C3PAO
Typical cost	$5,000–$60,000 (from $2,500 on AuditNex)	$30,000–$75,000 assessment; $138k–$285k all-in
Basis	Trust Services Criteria	NIST SP 800-171 (110 controls)
Renewal	Annual report	3-yr cert + annual affirmations
Best for	B2B SaaS selling commercially	Defense contractors handling CUI

Which Do You Need?

You need SOC 2 if…

✓You sell to commercial enterprises
✓Buyers ask for a security attestation report
✓You want a lower-cost, flexible credential
✓You're not handling federal CUI

You need CMMC if…

✓You're a DoD contractor or subcontractor
✓You store, process, or transmit CUI
✓A defense contract requires Level 2 certification
✓You handle more than basic Federal Contract Information

How Much They Overlap

ⓘ

Both frameworks rest on a common security foundation — access control, encryption, monitoring, configuration management, and incident response. A company with a mature SOC 2 program has already implemented many of the NIST 800-171 controls CMMC requires, which can reduce CMMC remediation. But CMMC is far more prescriptive, requires a registered third-party assessor, and carries a much higher total cost.

SOC 2 vs CMMC (Level 2) FAQ

What is the difference between SOC 2 and CMMC?

SOC 2 is a voluntary commercial attestation issued by a CPA firm and based on the Trust Services Criteria. CMMC is a mandatory US Department of Defense certification based on NIST SP 800-171, required to handle Controlled Unclassified Information, and issued by a registered third-party assessor (C3PAO). CMMC is far more prescriptive and expensive.

Is CMMC or SOC 2 more expensive?

CMMC is significantly more expensive. A SOC 2 audit commonly runs $5,000–$60,000 (from $2,500 on the AuditNex network), while a CMMC Level 2 C3PAO assessment alone runs $30,000–$75,000 and total first-cycle certification averages $138,000–$285,000 once remediation and documentation are included.

Can a SOC 2 report help with CMMC?

Indirectly. SOC 2 and CMMC share many security controls, so a mature SOC 2 program means you've likely already implemented part of NIST 800-171, reducing CMMC remediation work. But a SOC 2 report does not substitute for CMMC certification — only a registered C3PAO assessment satisfies the DoD requirement.

Do I need both SOC 2 and CMMC?

Only if you serve both markets. A company selling SaaS commercially and also holding DoD contracts that involve CUI would need SOC 2 for commercial buyers and CMMC Level 2 for defense work. If you only do one, you only need that framework.
