FedRAMP Reference

The Federal Risk and Authorization Management Program (FedRAMP) establishes the federal government's standardized approach to security assessment, authorization, and continuous monitoring for cloud services. This reference covers the program's definitional scope, operational structure, common authorization scenarios, and the decision criteria that determine when FedRAMP applies versus adjacent compliance frameworks. Federal agencies, cloud service providers, and third-party assessors navigating cloud procurement and authorization use this program as the binding framework.

Definition and scope

FedRAMP is a government-wide program administered by the General Services Administration (GSA), with policy authority derived from the Federal Information Security Modernization Act of 2014 (FISMA, 44 U.S.C. § 3551 et seq.) and Office of Management and Budget (OMB) Circular A-130. The program applies to cloud products and services used by federal executive branch agencies, establishing a "authorize once, use many times" model that eliminates duplicative agency-by-agency security reviews.

Scope boundaries are defined by cloud deployment model. FedRAMP applies to Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) offerings procured by federal agencies. On-premises systems, agency-owned data centers, and non-cloud managed services fall outside FedRAMP's direct authorization requirements, though they may be subject to FISMA controls independently.

The program operates under three impact levels drawn from NIST Federal Information Processing Standard (FIPS) 199:

1. Low — Systems where a breach would have limited adverse effect on agency operations, assets, or individuals.
2. Moderate — Systems where a breach would have serious adverse effect; this level covers the majority of FedRAMP authorizations, as the FedRAMP Marketplace reflects.
3. High — Systems where a breach would have severe or catastrophic effect, applicable to law enforcement, emergency services, financial systems, and health records.

A fourth designation, FedRAMP Tailored (LI-SaaS), was introduced for low-impact software-as-a-service offerings with limited federal data footprint, reducing the control baseline to approximately 37 controls compared to the 125+ required at the Moderate level.

How it works

FedRAMP authorization follows a structured process governed by the FedRAMP Program Management Office (PMO), housed within GSA. Two primary authorization paths exist:

1. Agency Authorization — A specific federal agency sponsors a cloud service provider (CSP) through assessment and issues an Authority to Operate (ATO). The authorization package is then made available to other agencies via the FedRAMP Marketplace.
2. Joint Authorization Board (JAB) Authorization — The JAB, composed of the Chief Information Officers of the Department of Defense (DoD), Department of Homeland Security (DHS), and GSA, issues a Provisional Authority to Operate (P-ATO). JAB review is reserved for cloud services with broad government-wide applicability.

The assessment process requires engagement of a Third Party Assessment Organization (3PAO) accredited by the American Association for Laboratory Accreditation (A2LA) under the FedRAMP 3PAO requirements program. The 3PAO conducts an independent security assessment against the applicable control baseline, which is derived from NIST SP 800-53 Rev. 5 and supplemented by FedRAMP-specific control enhancements.

Following initial authorization, CSPs must maintain continuous monitoring, submitting monthly vulnerability scans, annual security assessments, and incident reports within defined windows — significant incidents must be reported within 1 hour of detection under FedRAMP Incident Communications Procedures.

Common scenarios

The Digital Security Listings reflects the range of service categories where FedRAMP authorization is a procurement prerequisite. Common authorization scenarios include:

• Federal agency cloud migration — An agency moving email or document management to a commercial SaaS platform requires a FedRAMP Moderate ATO before production use, regardless of whether the vendor holds commercial certifications such as ISO 27001 or SOC 2 Type II.
• Defense contractor cloud use — DoD contractors subject to DFARS 252.204-7012 must use FedRAMP Moderate or higher cloud services for Covered Defense Information (CDI), a requirement reinforced by the Cybersecurity Maturity Model Certification (CMMC) framework.
• State and local government adoption — While FedRAMP is not legally mandatory for non-federal entities, state agencies receiving federal grants increasingly reference FedRAMP Marketplace status as a procurement filter under guidance from the Cybersecurity and Infrastructure Security Agency (CISA).
• Healthcare cloud platforms — Federal health agencies such as the Department of Veterans Affairs (VA) require FedRAMP authorization for cloud platforms processing protected health information, layering FedRAMP requirements alongside HIPAA Security Rule obligations (45 CFR Part 164).

Decision boundaries

The central distinction in applying FedRAMP is whether a system qualifies as a cloud service used by a federal executive agency. Private sector deployments with no federal agency customers are not subject to FedRAMP regardless of data sensitivity. The presence of a federal contract alone does not trigger FedRAMP — the obligation attaches specifically to cloud services that process, store, or transmit federal data.

FedRAMP versus FISMA authority is a frequent source of ambiguity. FISMA governs all federal information systems, including agency-owned infrastructure; FedRAMP is the cloud-specific implementation mechanism within the FISMA ecosystem. A CSP with a FedRAMP ATO satisfies the FISMA security review requirement for that cloud system, but agencies must still issue their own ATO incorporating the FedRAMP package under their internal risk management process.

The distinction between FedRAMP Moderate and FedRAMP High carries procurement consequences. High baseline requires 421 control requirements compared to Moderate's 325, and fewer than 20 cloud offerings held a FedRAMP High authorization as of the most recent FedRAMP Marketplace data, making vendor selection substantially more constrained for high-impact use cases.
