FedRAMP Equivalency: What It Means & Who Needs It

A cloud service that stores, processes, or transmits covered defense information for a Department of War (DoW, formerly the Department of Defense) contractor must meet security requirements equivalent to the Federal Risk and Authorization Management Program (FedRAMP) Security Controls Baseline Rev5 Moderate baseline.

That single DFARS cloud clause created a compliance category that exists nowhere else in federal cloud policy: FedRAMP equivalency. For defense contractors and Software-as-a-Service (SaaS) vendors selling into the defense industrial base (DIB), that DFARS clause is the procurement trigger. The requirements and limits are specific to that DoW contracting context.

Using the label precisely matters because the FedRAMP Program Management Office (PMO) does not recognize "FedRAMP equivalent" as a designation. A vendor that uses it loosely can create the exact confusion the PMO warning is meant to prevent. Equivalency requires an evidence package assessed by a FedRAMP-recognized independent assessment service (the assessor role FedRAMP previously designated a Third-Party Assessment Organization, or 3PAO). It produces neither a FedRAMP authorization nor a Marketplace listing.

Key Takeaways

• DoW-specific pathway. Defined by a DoD Chief Information Officer (CIO) FedRAMP equivalency memorandum, December 21, 2023, under DFARS 252.204-7012, it lets defense contractors use cloud services that meet the FedRAMP Moderate baseline without a formal FedRAMP authorization.  
• Authorization limits. It produces neither a FedRAMP Marketplace listing nor a government-issued Authority to Operate (ATO). Civilian agencies cannot reuse it. The DoD CIO states explicitly that equivalency does not confer authorization.  
• Higher control bar. Equivalency demands 100 percent compliance with all FedRAMP Moderate controls, assessed by a FedRAMP-recognized independent assessment service with zero control-related findings, then revalidated annually.  
• Narrow market access. With no government registry of equivalent services, every defense contractor must independently validate a vendor's evidence package. Full authorization remains the only path to government-wide reuse.

FedRAMP Equivalency Applies to a Specific DoW Contracting Path

FedRAMP equivalency applies only in the DoW contracting context. It originates in DFARS 252.204-7012, which requires that when a defense contractor uses an external cloud service provider (CSP) to store, process, or transmit covered defense information, the provider must "meet security requirements equivalent to those established by the Government for the Federal Risk and Authorization Management Program (FedRAMP) Moderate baseline."

For years, the DFARS cloud-service language used the term "equivalent" without defining a test for it. The DoD Chief Information Officer resolved that on December 21, 2023, with the memorandum "Federal Risk and Authorization Management Program (FedRAMP) Moderate Equivalency for Cloud Service Providers' (CSP) Cloud Service Offerings (CSOs)." The memo set a precise standard: 100 percent compliance with the FedRAMP Security Controls Baseline Rev5 (Current) Moderate controls, verified through an assessment conducted by a FedRAMP-recognized independent assessment service.

The DoD CIO's own briefing materials add the caveat that matters most: FedRAMP Moderate Equivalency does not confer FedRAMP Moderate Authorization.

Equivalency Differs from Full Authorization in Three Ways

Both paths start from the same 323-control Moderate baseline. The outcomes diverge in ways that determine market access.

• No FedRAMP Marketplace listing. Equivalency produces neither a Marketplace listing nor a public designation that buyers can independently verify.  
• No reuse across civilian agencies. Equivalency confers no standing with civilian agencies. Every federal buyer outside the DIB would have to restart the authorization process.  
• DoW-specific scope with no government-issued ATO. Equivalency produces no FedRAMP PMO authorization. It stays in the DoW contractor-assessment context, where a FedRAMP-recognized independent assessment service assesses the CSP’s evidence, and the contractor’s Cybersecurity Maturity Model Certification (CMMC) Third-Party Assessment Organization (C3PAO) reviews that body of evidence for FedRAMP Moderate equivalency.

A reusable authorization outcome is the distinction at the center of FedRAMP ATO: the authorization is useful because other buyers can recognize and reuse it. Equivalency cannot create that public status.

Demonstrating Equivalency Requires Several Steps

Equivalency requires every FedRAMP Moderate control, a FedRAMP-recognized independent assessment service assessment, contractor validation, and continuous monitoring.

1. Implement Every Control in the FedRAMP Moderate Baseline

The memo requires 100 percent compliance with all 323 controls. The assessment allows neither partial credit nor deferred implementation. It also permits no control-related Plan of Action and Milestones (POA&M). This is stricter than full authorization, where an authorizing official can accept residual risk and grant an ATO with open POA&Ms.

2. Complete an Assessment by a FedRAMP-Recognized Independent Assessment Service

The independent assessor produces the Body of Evidence (BoE), which includes three parallel artifacts:

• A System Security Plan with supporting policies, contingency and incident response plans, and a Federal Information Processing Standards (FIPS) 199 categorization.  
• A Security Assessment Plan with penetration testing methodology.  
• A Security Assessment Report with a risk exposure table and infrastructure scan results.

Those three artifacts document the control environment a contractor must validate for equivalency.

3. Secure Validation From the Defense Contractor

No government registry of equivalent services exists. Each DIB contractor must validate the BoE against Moderate Equivalent standards itself, approve use of the offering, confirm the CSP maintains an incident response plan, and accept responsibility for reporting if the service is compromised. That repeated private review is the operational cost that separates equivalency from reusable authorization.

4. Maintain the Posture Continuously

Continuous monitoring requires monthly vulnerability scans. Annual obligations include penetration tests and an independent assessment service reassessment. The obligations mirror post-ATO requirements under full authorization, without the reusable authorization that those obligations normally require.

During CMMC certification assessments, a C3PAO reviews the BoE, and the Defense Industrial Base Cybersecurity Assessment Center (DIBCAC) validates compliance with DFARS clauses 252.204-7012 and 252.204-7020. That validation burden narrows the set of vendors for which equivalency makes business sense.

Equivalency Suits a Narrow Set of Vendors (and Only Narrowly)

Equivalency works best when your federal sales plan centers on the defense supply chain. It requires no federal agency sponsor (historically one of the longest poles in the authorization tent), DIBCAC runs validation, and it can bridge a single DoW contract while the larger investment question stays open. It also helps vendors caught by DFARS 252.204-7012 flow down requirements before they planned to. But equivalency is a private arrangement, and private arrangements do not scale.

Vendors choosing this path should be clear-eyed about what it still leaves on the table:

• No Marketplace listing or government-issued ATO to signal authorization to civilian buyers.  
• No reuse across agencies. Every prime and every contract triggers fresh validation of the evidence package.  
• Full operational burden. 323 controls at zero findings, annual independent assessment service reassessment, monthly scans, and annual penetration testing.  
• Liability sits with the contractor, giving primes every incentive to prefer authorized vendors.  
• Durable federal market access still requires full FedRAMP authorization.

Full FedRAMP Authorization Delivers What Equivalency Cannot

The historical case for FedRAMP equivalency rested on the economics of full authorization. The traditional path often meant finding an agency sponsor, waiting 12 to 36 months, and absorbing costs that ran into the millions. A DoW-only workaround was a rational hedge against that expense. Those economics have shifted.

Pre-authorized infrastructure boundaries change the calculation. When a cloud platform has already carried its underlying controls through FedRAMP assessment, vendors deploying onto it can inherit eligible controls rather than duplicating them within their own boundary or assessment.

That inheritance model compresses the work behind FedRAMP timelines and costs, because the vendor only has to assess what is genuinely unique to its application. As the price of a real authorization converges with the price of the workaround, the workaround loses its reason to exist. Equivalency demands nearly the same operational discipline without producing the public authorization asset that opens the rest of the federal market.

90 Days at 90% Less Changes the Equivalency Calculus

If the assessment work behind equivalency is already approaching full authorization, the rational move is to invest that same effort in an outcome that every agency and every prime can reuse. Equivalency solves a narrow, temporary problem. Authorization opens the market, and with pre-authorized infrastructure available, the barrier that once justified the workaround has largely fallen.

Knox Systems offers a government cloud platform that enables SaaS companies to achieve federal authorization in approximately 90 days at roughly 90% less than the traditional cost: around $500,000 per application versus the $3.5 million industry norm.

Vendors deploy into Knox's pre-authorized environment spanning Amazon Web Services (AWS), Azure, and Google Cloud Platform (GCP), inherit 60% to 80% of required controls on day one, and rely on Knox's automated continuous monitoring to sustain evidence for both authorization and equivalency.

Knox supports FedRAMP Moderate, FedRAMP High, and DISA Impact Level 4, with IL-5 in process (estimated December 2026). It uses an independent assessor, and advisory and assessment tracks are contractually separate.

If DoW contracts are in your pipeline and the civilian market sits anywhere on your roadmap, book a meeting to scope your fastest path to full authorization.

FAQs About FedRAMP Equivalency

Does the CMMC Phase 2 Suspension Change FedRAMP Equivalency Requirements?

The July 2026 CMMC Phase 2 suspension targets the third-party assessment rollout and certification schedule. DFARS 252.204-7012 and the December 2023 equivalency memo remain in effect.

Can Encryption Substitute for Equivalency When Storing CUI in the Cloud?

Encrypted CUI stored in an external cloud service still requires the contractor to ensure the CSP meets FedRAMP Moderate baseline security requirements. The cloud service remains in scope.

Do SOC 2 or ISO 27001 Reports Satisfy FedRAMP Equivalency?

Equivalency requires a FedRAMP-recognized independent assessment service assessment against the full FedRAMP Moderate baseline with zero control-related findings. Commercial audit frameworks and vendor self-attestations are outside the scope of the DoW-required assessment.

How Long Does an Equivalency Assessment Take?

The December 2023 memo defines the evidence package and validation standard. You'll need to assess the underlying control environment before setting a schedule, because remediation drives the timeline more than the assessment itself.
