A FedRAMP authorization package centers on four documents: the System Security Plan, the Security Assessment Plan, the Security Assessment Report and the Plan of Action and Milestones, plus an authorization letter from the agency. Reviewers look hardest for places where those documents contradict each other or your diagrams.
What is in the package?
According to FedRAMP's Rev5 playbook for agency authorization, the package covers the SSP with its appendices, the SAP, the SAR, the POA&M (SSP Appendix O) and the agency's authorization letter. Other required SSP appendices include security policies and procedures and the incident response plan. The authoritative list is the FedRAMP initial authorization package checklist, which cloud providers must complete, so use that, not this summary.
Who writes what: the cloud service provider drafts the SSP from FedRAMP templates, and the accredited third party assessment organization (3PAO) validates it. The 3PAO produces the SAP and SAR, which the provider reviews and signs off. After testing, the 3PAO's SAR carries findings and a recommendation, and the provider builds the POA&M from those findings.
What do reviewers look for?
The playbook lists common gaps, and they are about consistency: the SSP and its diagrams disagreeing, the SAR and POA&M not matching, and control narratives that differ from what the 3PAO found. Sometimes the 3PAO must do delta testing to validate fixes or extra testing if the agency spots gaps in scope. FedRAMP recommends a just-in-time approach, delivering artifacts iteratively instead of all at once, to avoid rework after testing.
Providers and 3PAOs cannot alter or remove content in the SSP, SAP and SAR templates, other than removing the italic instructions before final submission.
What evidence supports the documents?
Documents describe controls. Evidence shows them operating. Reviewers will expect things such as an accurate component inventory within the authorization boundary, vulnerability scan results mapped to inventory entries, and records of how findings were handled. Safeguard's FedRAMP framework page lists six requirements a scan decides against the software inventory: system component inventory, inventory granularity with versions, software integrity verification through known-good hashes, vulnerability scanning correlation through standard identifiers, supply chain provenance, and identifiable, dated authorization artifacts. It also lists 11 catalog controls that need your own evidence, including account management, configuration baselines, incident reporting within FedRAMP time frames, encryption at rest, audit log review, maintaining the SSP, engaging an accredited 3PAO and a continuous monitoring program.
That page also says no automated tests are mapped to FedRAMP by default and it does not say that using Safeguard makes an organization compliant. Importantly, Safeguard's compliance documentation states it does not hold a FedRAMP authorization and is not on the FedRAMP Marketplace, and that its FedRAMP HIGH and IL5 sections describe design goals.
A consistency checklist
Before you hand the package over, test it yourself.
| Check | Question |
|---|---|
| Diagram to SSP | Does every component in the diagram appear in the SSP, and the reverse? |
| Inventory to scans | Does every inventory entry have scan coverage? |
| SAR to POA&M | Does every SAR finding have a POA&M entry with an owner and date? |
| Narrative to reality | Would the 3PAO's test results match what the control narrative says? |
| Dates | Are artifacts dated and in a coherent order? |
What to do
- Get the current initial authorization package checklist from FedRAMP and treat it as the source of truth.
- Reconcile diagrams, inventory and SSP before the 3PAO starts.
- Deliver artifacts iteratively and review each with the 3PAO.
- Build the POA&M straight from the SAR, one row per finding.
- Keep dated evidence, such as scans and inventories, for every control you narrate.
Quick check
Who writes the Security Assessment Report?
The 3PAO. The cloud provider reviews and signs off on it, then builds the POA&M from its findings.
Does a compliance tool make you FedRAMP authorized?
No. Authorization comes through the FedRAMP process. Tools can help organize evidence.
