What is the core difference between SOC 2 and CMMC?

SOC 2 is an AICPA attestation that a CPA firm issues to prove a service organization protects customer data against the Trust Services Criteria. CMMC is a US Department of Defense certification, assessed by a C3PAO, that proves a contractor protects Federal Contract Information and Controlled Unclassified Information against NIST SP 800-171. Different bodies, different auditors, different rule books.

Who actually has to pursue CMMC vs SOC 2?

CMMC is mandatory for any organization in the DoD supply chain that handles FCI or CUI on a contract that includes the CMMC clause. SOC 2 is voluntary, but enterprise SaaS buyers often require a Type II report before signing. If you sell to enterprises, SOC 2 is a market expectation. If you sell to the DoD, CMMC is contractual.

Does Pilotcore help with SOC 2?

No. Pilotcore focuses on CMMC for US defense contractors and CPCSC for Canadian defense contractors. SOC 2 sits outside our scope. If SOC 2 is what you need, find a CPA firm that issues SOC 2 reports and a readiness consultancy that specializes in the AICPA Trust Services Criteria.

Can a SOC 2 Type II report substitute for CMMC?

No. SOC 2 and CMMC overlap on common security controls (access management, encryption, monitoring), but a SOC 2 report does not satisfy any CMMC requirement on its own. CMMC has specific NIST SP 800-171 controls, CUI marking and handling rules, and DoD-specific incident reporting that SOC 2 does not cover.

SOC 2 vs CMMC: Which Framework Do You Actually Need?

Side by side

Two frameworks, two buyers, two audit paths.

SOC 2 vs CMMC quick answer

Choose SOC 2 when enterprise software buyers need assurance that your service protects customer data. Choose CMMC when a US Department of Defense contract, prime contractor, or flowdown requirement says your organization must protect FCI or CUI under the CMMC rule set. If both buyer paths apply, treat them as separate programs with some shared control work, not as substitutes.

Question	SOC 2	CMMC
Main buyer trigger	Enterprise SaaS procurement and security review.	US DoD contracts, prime contractor flowdown, FCI, or CUI handling.
Assessment path	CPA firm attestation against Trust Services Criteria.	Self-assessment or C3PAO assessment depending on level and contract need.
What it proves	Controls over customer data for a service organization.	Controls for federal contract information and controlled unclassified information.
Can it replace the other?	No. SOC 2 does not satisfy CMMC requirements.	No. CMMC does not issue a SOC 2 report for SaaS procurement.

SOC 2

AICPA attestation, voluntary
Issued by a CPA firm
Trust Services Criteria (Security, Availability, Confidentiality, Processing Integrity, Privacy)
Type I (point-in-time) or Type II (3-12 month observation window)
Buyer audience: enterprise SaaS customers
Annual recertification

CMMC

DoD certification, mandatory under DFARS 252.204-7021 once the clause is in the contract
Assessed by a C3PAO (Level 2+) or self-attested (Level 1)
Based on NIST SP 800-171 Rev 2 (currently) for Level 2
Three levels (1, 2, 3) tied to data sensitivity (FCI vs CUI)
Buyer audience: US Department of Defense and prime contractors
Recertification every 3 years

Quick triage

Which one applies to you?

You need CMMC if:

You sell to the US Department of Defense, directly or as a subcontractor
Your contracts already include the DFARS 252.204-7012 clause and the new CMMC flowdown
You handle Federal Contract Information (FCI) or Controlled Unclassified Information (CUI)

If you are a Canadian defense contractor, the equivalent regime is CPCSC, not CMMC. See What is CPCSC? and CPCSC vs CMMC.

You need SOC 2 if:

You sell B2B SaaS and your enterprise prospects ask for a SOC 2 report during security review
Your investors or insurers require independent assurance of security controls
You don't sell to the DoD and you don't handle CUI

Our scope

Where Pilotcore fits, and where we don't.

Pilotcore focuses on CMMC for US defense contractors and CPCSC for Canadian defense contractors. We don't take SOC 2 engagements. SOC 2 sits inside the CPA-firm world, where the report itself has to be issued by a licensed CPA, and a different set of consultancies specialize in that work.

If SOC 2 is what your buyers are asking for, look for a CPA firm that issues SOC 2 reports and a readiness partner that lives in the AICPA Trust Services Criteria full time.

If you are confused about which framework actually applies, the deciding factor is almost always your buyer. DoD prime or sub? CMMC. Enterprise SaaS customer? SOC 2. Both? You probably need both, and you'll want CMMC sequenced first if you have an active DoD contract on the line.

Confirming a CMMC or CPCSC path?

If your contracts point to CMMC or CPCSC, we can scope a readiness assessment, produce the SSP, and help you close NIST SP 800-171 gaps before a C3PAO assessment.
