CMMC 2.0 to FedRAMP: control mapping & evidence reuse
9 of 13 control domains map directly. See exactly where CMMC 2.0 and FedRAMP overlap, which evidence carries over, and which engagement to run first.
How CMMC 2.0 and FedRAMP relate
Organizations in the defense industrial base that handle Controlled Unclassified Information (CUI) must meet CMMC 2.0 Level 2 to keep working on Department of Defense contracts. Some of those same companies, or cloud service providers that want to sell to federal agencies, also need a FedRAMP authorization. Both programs are United States government-driven rather than commercial, so it is common for a growing GovCon or cloud vendor to face both at different stages of its lifecycle.
Structurally, the two frameworks share the same NIST DNA, which is why their control language lines up so well. CMMC 2.0 Level 2 is exactly the 110 practices of NIST SP 800-171 Rev. 2, organized into 14 families. FedRAMP builds on the NIST SP 800-53 Rev. 5 baselines (Low, Moderate, and High, where Moderate is 323 controls). Critically, 800-171 was itself tailored down from the 800-53 Moderate baseline to protect CUI on nonfederal systems, so most CMMC practices trace back to a broader 800-53 control.
This crosswalk is practical planning guidance from AuditNex, not an official Department of Defense or FedRAMP PMO mapping. CMMC Level 2 is assessed by accredited C3PAOs, while FedRAMP is assessed by accredited 3PAOs and finalized with a sponsoring agency Authorization to Operate (ATO). Use the row-by-row confidence ratings below to see where evidence reuses cleanly and where FedRAMP demands materially more rigor.
Domain-by-domain mapping
Each row pairs the closest CMMC 2.0 and FedRAMP requirements for one control domain. This is practical audit-planning guidance, not an official crosswalk published by the standards bodies.
Across 13 control domains, 9 map directly between CMMC 2.0 and FedRAMP, 3 map partially, and 1 have no equivalent on one side. Counts are computed live from the mapping table below.
| Control domain | CMMC reference | FedRAMP reference | Match & notes |
|---|---|---|---|
| Governance & risk assessment | RA 3.11.1 risk assessment; CA 3.12.1–3.12.4 security assessment & SSP | RA family; CA family; PL planning | Direct match Both are NIST-derived and require formal risk assessment, control assessment, and a system security plan. FedRAMP layers on agency authorization (ATO) and ongoing authorization oversight beyond the CMMC C3PAO assessment. |
| Policies & documentation | CA 3.12.4 system security plan (policy embedded across the 14 families) | PL planning; per-family policy and procedures controls (e.g., AC-1) | Partial CMMC 800-171 embeds policy requirements across its families and requires an SSP rather than dedicated policy controls, while FedRAMP mandates an explicit policy and procedures control in each 800-53 family plus PL planning. The intent overlaps but FedRAMP's documentation set is more granular. |
| Access control & identity | AC 3.1.x access control; IA 3.5.x identification & authentication | AC family; IA family | Direct match Access control and identity requirements map closely because 800-171 was tailored from the 800-53 Moderate baseline. FedRAMP applies more control enhancements per family, so evidence usually needs extension rather than rework. |
| Change management | CM 3.4.3–3.4.4 change control | CM family (CM-3) | Direct match Both require documented configuration change control and approval of changes. FedRAMP's CM baseline is broader, with more enhancements and formal change boards than the CMMC 3.4.3–3.4.4 practices. |
| Data protection & encryption | SC 3.13.x incl. 3.13.11 FIPS-validated cryptography for CUI; MP 3.8.x media protection | SC family (SC-8, SC-13, SC-28) | Direct match Both mandate encryption of data in transit and at rest, and CMMC specifically requires FIPS-validated cryptography for CUI, which aligns with FedRAMP SC-13. FedRAMP adds more detailed key management and boundary protection expectations. |
| Logging & monitoring | AU 3.3.x audit & accountability; SI 3.14.x monitoring | AU family; SI family; continuous monitoring (ConMon) | Direct match Audit logging, review, and system monitoring requirements align directly. FedRAMP additionally requires monthly continuous monitoring reporting to the authorizing agency, which exceeds the CMMC cadence. |
| Incident response | IR 3.6.x incident response | IR family | Direct match Both require incident handling, tracking, and reporting capabilities. FedRAMP defines reporting timelines to the agency and US-CERT, while CMMC ties cyber incident reporting to DFARS obligations. |
| Vendor & third-party risk | AC 3.1.20 external systems; DFARS 252.204-7012 flow-down | SA family (SA-9 external system services) | Partial CMMC has no dedicated third-party risk family and relies on external-systems requirements plus DFARS flow-down to subcontractors. FedRAMP's SA family, including SA-9, addresses external service providers more directly, so this maps only partially. |
| Business continuity & availability | No direct equivalent | CP contingency planning family (CP-9 backup, CP-10 recovery) | No equivalent NIST SP 800-171 has no contingency-planning or business-continuity family, so CMMC Level 2 does not require backup or disaster recovery controls. FedRAMP's CP family requires contingency planning, backups, and recovery, so there is no CMMC counterpart. |
| Personnel security & training | PS 3.9.x personnel security; AT 3.2.x awareness & training | PS family; AT family | Direct match Personnel screening, termination, and security-awareness training map directly between the two. FedRAMP baselines add role-based training and more detailed personnel controls. |
| Asset & configuration management | CM 3.4.1–3.4.2 baseline configuration & inventory | CM family (CM-8 component inventory) | Direct match Both require baseline configurations and component inventories under their CM families. FedRAMP's CM-8 inventory and configuration controls are more prescriptive than the CMMC 3.4.1–3.4.2 practices. |
| Physical & environmental security | PE 3.10.x physical protection | PE physical & environmental family | Partial CMMC covers physical access, escort, and monitoring, but 800-171 has no environmental controls, whereas FedRAMP's PE family adds power, fire, temperature, and similar protections. The physical-access portion aligns while environmental protection is FedRAMP-only scope, so this is partial. |
| Vulnerability & patch management | RA 3.11.2 vulnerability scanning; SI 3.14.1 flaw remediation | RA-5 vulnerability scanning; SI-2 flaw remediation (monthly ConMon) | Direct match Both require periodic vulnerability scanning and timely flaw remediation. FedRAMP prescribes monthly scanning under continuous monitoring, a stricter cadence than the CMMC periodic requirement. |
Which should you do first?
Most defense-sector companies reach CMMC first because the contract requirement is concrete: DoD work that involves CUI requires Level 2, and the scope is focused on the 110 practices of 800-171. FedRAMP is usually pursued later and only when the company decides to offer a cloud service to federal agencies. Because 800-171 is a tailored subset of the 800-53 Moderate baseline, the CMMC effort feeds forward into FedRAMP, but the reverse economy does not apply in the same way.
If a company already knows it will need both, the efficient path is to design the System Security Plan and control implementation to the broader 800-53 Moderate baseline from the start, then map down to the 110 CMMC practices for the C3PAO assessment. Adopting FedRAMP's continuous monitoring discipline, including monthly vulnerability scanning, will comfortably satisfy the CMMC expectation for periodic scanning and flaw remediation.
Keep the market reality in mind while staging the work. Neither program can be self-attested at these levels: CMMC Level 2 requires a C3PAO assessment and FedRAMP requires a 3PAO assessment. FedRAMP additionally requires a sponsoring federal agency willing to grant an ATO, which is a business and program gate, not just a technical one, so the FedRAMP timeline depends on factors outside the control set.
Evidence you can reuse
Because both frameworks speak the same NIST control language, a large share of artifacts carries over. Access control and identity configurations, multi-factor authentication evidence, FIPS-validated encryption settings, audit logging configurations, incident response plans, configuration baselines and component inventories, vulnerability scan reports, and personnel screening and security-awareness training records generally map directly. The System Security Plan and Plan of Action and Milestones structure also translate, since CMMC and FedRAMP both organize evidence around those documents.
Some FedRAMP obligations have no CMMC counterpart and require new work. Contingency planning, backup, and disaster recovery evidence from the CP family is absent in 800-171, so it must be built fresh for FedRAMP. FedRAMP also expects monthly continuous monitoring deliverables, environmental physical controls evidence in the PE family, and a full authorization package (authorization boundary and tailoring to a complete 800-53 baseline) that goes well beyond CMMC. The assessment outputs themselves, a C3PAO assessment versus a 3PAO Security Assessment Report plus an agency ATO, are distinct and not interchangeable.
