The process
Getting authorized is a lifecycle, not a one-time test. It runs from readiness, through a full assessment and authorization decision, into ongoing continuous monitoring.
The lifecycle at a glance
-
Preparation & readiness
The cloud service provider (CSP) documents its system and, optionally, works with a 3PAO to produce a Readiness Assessment Report (RAR). A successful RAR earns the FedRAMP Ready designation and signals the service is a strong candidate for authorization.
-
Full security assessment
The CSP writes a detailed System Security Plan (SSP) describing how it meets every control in its baseline. An independent, accredited 3PAO then tests the system against a Security Assessment Plan (SAP) and documents the results in a Security Assessment Report (SAR).
-
Authorization decision
The agency's Authorizing Official reviews the complete package — SSP, SAR, and a Plan of Action & Milestones (POA&M) for any open findings — and weighs the residual risk. If acceptable, they issue an Authorization to Operate (ATO).
-
Continuous monitoring (ConMon)
Authorization is not the finish line. The CSP continuously monitors its security posture — submitting monthly vulnerability scans, keeping the POA&M current, reporting incidents, and undergoing an annual assessment — so the authorization stays valid over time.
The key documents
| Document | Purpose | Who produces it |
|---|---|---|
| RAR | Readiness Assessment Report — early attestation that the service can likely be authorized. | 3PAO |
| SSP | System Security Plan — the detailed description of how each control is implemented. | CSP |
| SAP | Security Assessment Plan — the methodology and scope for testing the system. | 3PAO |
| SAR | Security Assessment Report — the findings from the independent assessment. | 3PAO |
| POA&M | Plan of Action & Milestones — the tracked plan to remediate open findings. | CSP |
How long it takes
There's no single answer. A well-prepared service with an engaged agency sponsor might move through assessment in several months; less-prepared efforts can take much longer. The biggest accelerators are:
- Strong documentation — a clear, complete SSP saves enormous back-and-forth.
- An engaged agency sponsor — the authorization can't be issued without one.
- A mature security posture — fewer open findings means a faster decision.
FedRAMP's modernization work (FedRAMP 20x) aims to compress these timelines by automating evidence collection and validation.
