Realistic Fastest Timeline
The fastest FedRAMP authorization is Li-SaaS at 6 to 9 months. A Low baseline takes 9 to 15 months, and Moderate takes 12 to 24 months. These timelines assume a dedicated team and an agency sponsor (not the JAB path).
| Phase | Li-SaaS Timeline | Moderate Timeline |
|---|---|---|
| Scoping and agency sponsor | Months 1 – 2 | Months 1 – 3 |
| SSP development and control implementation | Months 2 – 4 | Months 3 – 12 |
| 3PAO assessment | Months 4 – 5 | Months 12 – 18 |
| Agency review and ATO | Months 5 – 6 | Months 18 – 24 |
The Sprint Approach: Parallelize Everything
- Month 1: Secure an agency sponsor, engage a 3PAO, and onboard your automation platform simultaneously.
- Months 2-3: Begin SSP development and control implementation in parallel. Use OSCAL automation to generate the SSP while engineering implements controls.
- Month 4: Start 3PAO readiness assessment while continuing to close control gaps.
- Month 5: 3PAO formal assessment. Pre-organized evidence from your automation platform accelerates fieldwork.
Our Recommendation
LowerPlane's AI-powered platform can accelerate FedRAMP readiness by automating OSCAL-formatted SSP generation, continuous monitoring evidence collection, and POA&M tracking. The platform maps controls to FedRAMP baselines and provides a 3PAO-ready evidence portal, cutting assessment timelines by 20 – 30%.
Automation Shortcuts That Save Months
- OSCAL-native SSP generation. Produce machine-readable SSPs that 3PAOs and agencies can process faster than traditional Word documents.
- Infrastructure-as-code scanning. Automatically verify control implementation against your cloud configuration.
- Continuous monitoring automation. Set up ConMon from day one so evidence accumulates while you work on other controls.
- Inherited control documentation. Automatically document which controls you inherit from your FedRAMP-authorized IaaS provider.
Common Bottlenecks and How to Avoid Them
- Finding an agency sponsor. Start sales conversations with federal agencies early. You need a sponsor before you can begin the authorization process.
- SSP completeness. Incomplete SSPs are the number-one reason for delays. Use automated generation and validation.
- 3PAO scheduling. Book your 3PAO 2 – 3 months before you expect to be ready. Their calendars fill quickly.
- POA&M resolution. Open POA&M items can delay authorization. Prioritize closing high-risk items before the 3PAO assessment.
