Find Your Framework in 4 Questions

Answer four questions about your organization and we'll tell you which framework(s) apply — and why.

Question 1 of 4
Question 01 / 04
Do you hold or actively pursue DoD or federal government contracts?
This includes prime contracts and subcontracts where you transmit, receive, or generate information for a federal agency. If you're unsure, check your NAICS codes and contract vehicles.
Question 02 / 04
Do you handle CUI — Controlled Unclassified Information?
CUI includes technical data, export-controlled data (ITAR/EAR), personally identifiable information generated under a federal contract, and similar sensitive but unclassified information. Your contracts will reference DFARS 252.204-7012 if CUI is in scope. NARA CUI registry lists all categories.
Question 03 / 04
Do enterprise or institutional customers require audit reports as part of their vendor due diligence?
Large enterprises, financial institutions, healthcare organizations, and publicly traded companies routinely require SOC 2 Type II reports from SaaS vendors as part of procurement or annual vendor reviews. If you're closing deals over $100K ARR, this likely applies.
Question 04 / 04
Does your organization create, receive, maintain, or transmit electronic Protected Health Information (ePHI)?
If your platform touches patient records, clinical notes, insurance claims, medical device data, or any information that could identify an individual's health status in a medical context, HIPAA applies regardless of other frameworks.

Side-by-Side Comparison

CMMC Level 2 vs SOC 2 Type II

A structured comparison across the dimensions that matter most for compliance planning — governing body, cost, timeline, and legal basis.

Dimension
Framework Attribute
DoD Mandate
CMMC Level 2
Market Standard
SOC 2 Type II
Governing Body
DoD / Cyber AB — Department of Defense via 32 CFR Part 170; Cyber AB accredits C3PAOs
AICPA — American Institute of CPAs issues AT-C Section 205; no government involvement
Control Set
110 practices mapped directly to NIST SP 800-171 Rev 2 across 14 control families. Source: NIST SP 800-171 Rev 2
~60–80 criteria across 5 Trust Services Criteria (Security, Availability, Confidentiality, Privacy, Processing Integrity). Scope varies by engagement. [UNVERIFIED exact count]
Assessment Model
C3PAO (mandatory Phase 2) Mandatory  — accredited third-party assessment organization; self-assessment allowed only for select programs until Nov 2026
Licensed CPA firm Voluntary  — any AICPA-licensed CPA can perform; customer-driven demand makes it effectively mandatory for enterprise SaaS
Cost Range
$50K–$200K+ total program cost (remediation + assessment + annual operation). Assessment fees alone: $20K–$75K+. Source: DoD Cost Analysis; varies sharply by org size.
$20K–$100K+ per audit cycle. Readiness + gap assessment typically $10K–$30K additional. [UNVERIFIED]
Typical Timeline
12–24 months from gap assessment to C3PAO assessment, depending on starting posture. Remediation is the long pole. [UNVERIFIED]
3–12 months from readiness to Type II report (Type II requires a minimum 6-month observation period). Type I can be achieved in 2–4 months. [UNVERIFIED]
Certification Validity
3 years with annual affirmation required in SPRS. Source: 32 CFR § 170.21
12 months per report period; customers typically require a new Type II report annually covering the prior period
Legal Basis
32 CFR Part 170 (final rule effective Dec 16, 2024); DFARS 252.204-7012 (existing CUI safeguarding clause); DFARS 252.204-7021 (CMMC clause, being rolled into contracts). Source: Fed Register 89 FR 83093
Contractual / voluntary — no federal mandate; derives authority from customer contract terms and enterprise vendor security programs
Who Needs It
DIB contractors — any organization in the Defense Industrial Base that handles CUI or bids on DoD contracts (prime or sub)
SaaS / tech vendors selling to enterprise, financial services, healthcare, or other regulated industry customers that conduct security vendor reviews
With Each Other
~40% overlap in control intent across Access Control, Audit & Accountability, Incident Response, and System & Communications Protection families. If you start with CMMC, significant SOC 2 effort is already done. [UNVERIFIED — no authoritative crosswalk published]
Control Overlap Analysis

Where CMMC and SOC 2 Converge

Both frameworks share foundational security principles despite different regulatory origins. Understanding the overlap helps you plan dual-compliance efficiently. Note: No authoritative CMMC-to-SOC 2 crosswalk is published by either DoD or AICPA; the mapping below is based on control intent analysis. [UNVERIFIED]

CMMC L2 · NIST 800-171 Rev 2
AC — Access Control
14 practices covering least privilege, remote access, and mobile device policy. Maps strongly to CC6 (logical access) in TSC.
AU — Audit & Accountability
9 practices for audit log creation, review, and retention. Maps to CC7 (monitoring) in TSC.
IR — Incident Response
3 practices for incident handling and reporting. Maps to CC7.3–CC7.5 in TSC.
SC — System & Comms Protection
16 practices including network segmentation and encryption. Maps to CC6.1, CC6.7 in TSC.
RA — Risk Assessment
3 practices for vulnerability scanning and risk management. Maps to CC3 (risk assessment) in TSC.
CUI-specific controls
Media protection (MP), Personnel security (PS), Physical protection (PE), Configuration management (CM) — largely CMMC-only scope

SOC 2 · Trust Services Criteria
CC6 — Logical & Physical Access
Covers authentication, authorization, and separation of duties. Broad alignment with CMMC AC and IA families.
CC7 — System Operations
Monitoring, incident identification, and response. Aligns with CMMC AU and IR families.
CC2/CC4 — Comm & Monitoring
Internal communications about security, monitoring for threats. Overlaps with CMMC CA and AU families.
CC3 — Risk Assessment
Risk identification and treatment. Maps to CMMC RA-3 family practices.
Availability criteria (A)
System uptime, capacity planning, backup/recovery. Not a CMMC requirement — adds SLA/SRE context
Privacy criteria (P)
Personal information lifecycle management. Overlaps HIPAA if in scope; no direct CMMC equivalent
Key Insight

If you need both frameworks, start with CMMC. The 110 NIST 800-171 practices are significantly more prescriptive than SOC 2's principles-based Trust Services Criteria. An organization that achieves CMMC Level 2 will have evidence artifacts, policies, and technical controls that satisfy a substantial portion of SOC 2 Security TSC. The reverse is not true — SOC 2 alone leaves significant CMMC gaps (CUI handling, media protection, configuration baselines, SPRS reporting).

Dual-Compliance Path

Pursuing Both Frameworks? Here's How.

Defense SaaS companies — software vendors that sell to both DoD customers and commercial enterprise — routinely need CMMC Level 2 and SOC 2 Type II. The ~40% overlap means dual pursuit is feasible without doubling the budget. [UNVERIFIED — overlap estimate]

🗺
The CMMC-First Strategy
Build your controls program to CMMC Level 2 requirements first. The NIST 800-171 framework forces you to implement structured access control, audit logging, incident response, and configuration management — all of which produce evidence artifacts that directly satisfy SOC 2 criteria. Once CMMC evidence is in your GRC platform, a SOC 2 readiness assessment becomes a gap analysis, not a ground-up build.
💡
Where You Save Effort
Shared evidence artifacts: Access control policies, audit log configurations, incident response plans, risk assessments, and vendor management programs all satisfy requirements in both frameworks. A CMMC SSP doubles as context for SOC 2 system description. Shared tooling: SIEM, vulnerability scanner, PAM, and MFA controls count for both. You're not buying twice — you're claiming twice.
📅
Suggested Sequencing
1
Months 1–3: Gap assessment against NIST 800-171. Prioritize CUI boundary definition.
2
Months 4–12: Remediate CMMC gaps. Stand up SIEM, patch management, access reviews.
3
Month 12: Begin SOC 2 Type I. Map existing CMMC evidence to TSC. Fill availability/privacy gaps.
4
Months 13–18: SOC 2 observation period runs concurrently with CMMC C3PAO prep.
5
Month 18–24: C3PAO assessment + SOC 2 Type II report issued within the same quarter. [UNVERIFIED typical timeline]
⚠
Watch for Scope Conflicts
CUI boundary vs. SOC 2 system scope: Your CMMC authorization boundary should enclose your CUI processing environment. SOC 2 system scope is typically broader (all production infrastructure). These can diverge in ways that complicate evidence collection — document the difference explicitly in your SSP and SOC 2 description.

Timing conflict: C3PAO assessment scheduling is constrained by C3PAO availability (limited supply as of 2026). Don't schedule your SOC 2 audit for the same quarter without buffer.
