FedRAMP Authorization Checklist

FedRAMP authorization is the gateway to selling cloud services to the U.S. federal government, a market worth over $60 billion annually. The process is rigorous, time-consuming, and expensive, but for cloud service providers, it unlocks access to thousands of federal agencies with a single authorization. This checklist covers the complete FedRAMP authorization journey from initial readiness through continuous monitoring, aligned with the latest FedRAMP Rev. 5 baselines.

The formal assessment is the most intensive phase. Your 3PAO will evaluate your system against the applicable NIST 800-53 control baseline: Low Impact (156 controls), Moderate Impact (325 controls), or High Impact (421 controls). Each control is tested through interviews, document review, and technical testing. Plan for the assessment to take 4 to 8 weeks depending on system complexity. Expect findings that require remediation. Document all findings in your Plan of Action and Milestones (POA&M) with realistic remediation timelines.

Budget realistically. A Moderate Impact FedRAMP authorization typically costs $1 million to $3 million and takes 12 to 18 months from readiness assessment through ATO. Major cost categories include 3PAO assessment fees, SSP development, control implementation and remediation, staffing for continuous monitoring, and FedRAMP-compliant infrastructure and tooling. The ongoing cost of continuous monitoring is roughly 30 to 40 percent of the initial authorization cost per year.
