FedRAMP
By U.S. General Services Administration
S. government program that standardizes the security assessment, authorization, and continuous monitoring of cloud products and services used by federal agencies.
Definition
FedRAMP is a U.S. government program that standardizes the security assessment, authorization, and continuous monitoring of cloud products and services used by federal agencies. It requires cloud service providers to implement a NIST 800-53-based control baseline, undergo assessment by an accredited third-party organization, and obtain authorization either from an individual agency or a joint governance board, after which other agencies can reuse that authorization rather than repeating the process from scratch.
Overview
FedRAMP was established to solve a specific inefficiency: before it existed, every federal agency wanting to use a given cloud service had to conduct its own independent security assessment of that service, creating duplicated effort for both agencies and vendors. A cloud provider might undergo dozens of nearly identical assessments to sell the same product across government. FedRAMP created a "do once, use many times" model where a single rigorous authorization can be leveraged by any agency that wants to procure the service. Mechanically, a cloud service provider selects an impact level, low, moderate, or high, based on the sensitivity of data the service will handle, then implements the corresponding NIST 800-53 control baseline plus FedRAMP-specific overlays. An accredited Third Party Assessment Organization independently tests the implementation and produces a security assessment report. The provider then pursues authorization either through an individual federal agency, called an Agency Authorization, or through the Joint Authorization Board, a governance body historically composed of representatives from the Department of Defense, Department of Homeland Security, and General Services Administration, whose provisional authorization signals particularly strong readiness for broad reuse. FedRAMP sits directly on top of NIST 800-53 rather than replacing it: the control catalog provides the technical substance, while FedRAMP adds the process, governance, and continuous monitoring requirements specific to cloud services sold into government. It differs from commercial certifications like SOC 2 or ISO 27001 in that those are broadly applicable across industries, while FedRAMP exists exclusively to gate cloud procurement by U.S. federal agencies, with no equivalent standing in the private sector. In practice, cloud vendors pursue FedRAMP authorization specifically to sell into the federal market, since many agencies are restricted from procuring unauthorized cloud services for anything beyond limited pilots. Once authorized, a provider must maintain continuous monitoring, submitting regular vulnerability scan results and updated documentation to retain its authorization, and agencies can review the provider's authorization package in a shared repository before deciding whether to grant their own agency-specific authorization to operate. The process is notably slow and expensive, often taking well over a year and requiring significant investment in both the technical controls and the assessment and documentation overhead, which is a real barrier for smaller vendors. Even after authorization, individual agencies still perform their own risk acceptance before use, so a FedRAMP authorization is a strong signal rather than an automatic green light everywhere. Vendors not targeting the federal market generally find commercial frameworks like SOC 2 sufficient and skip FedRAMP entirely given its cost and government-specific focus.
Key Concepts
- Standardizes cloud security assessment across all U.S. federal agencies
- Built directly on the NIST 800-53 control catalog and baselines
- Uses accredited Third Party Assessment Organizations for independent testing
- Offers Agency Authorization or Joint Authorization Board authorization paths
- Enables authorization reuse across agencies once granted
- Requires ongoing continuous monitoring to maintain authorized status
- Gates cloud procurement decisions for most federal agency purchases
- Maintains a public repository of authorized cloud service offerings
