JAB Provisional Authorization to Operate is the gold standard for cloud service providers who want to sell to the federal government. The JAB (Joint Authorization Board) — NIST, DoD, GSA, and DHS — reviews the package, and once granted, other agencies can inherit it. The economic unlock is huge. The path to getting there is hard.
The package is not small: SSP (System Security Plan) documenting every NIST 800-53 Rev 5 control across a Moderate or High baseline, SAP (Security Assessment Plan) and SAR (Security Assessment Report) from a 3PAO (Third-Party Assessment Organization), POA&M (Plan of Action & Milestones) with remediation SLAs for every finding, and a ConMon (Continuous Monitoring) strategy with monthly vuln scans, annual assessments, and significant-change procedures.
Where teams actually lose time: control narratives. A Moderate baseline includes ~325 controls. Writing narrative text for each one — in the FedRAMP template, at the expected depth, with real evidence links — takes 500-800 hours the first time through. Teams that try to assign this by control family to subject-matter experts then spend the next three months editing for voice and completeness. Teams that try to do it with one technical writer spend four months waiting for SME review cycles.
The second time-sink: 3PAO fieldwork. The 3PAO will spend 4-8 weeks testing controls, and every gap they find becomes a POA&M item. POA&M items have hard SLAs — 30 days for Critical and High, 90 days for Moderate, 180 days for Low. Teams that go into 3PAO fieldwork with open gaps end up in a death march of evidence cleanup before the final SAR is signed.
The GovTech pack is built around this workflow. SSP control narratives live in one place with per-control implementation status, responsible role, inheritance source, and evidence links. POA&M items track remediation state with SLA clocks that auto-calculate from finding severity. 3PAO SAP, SAR, and monthly ConMon packages generate as formatted PDFs in the FedRAMP template. NIST 800-53 + 800-171 + 800-172 + CMMC + Privacy Act PIA + Section 508 + CISA BODs are all first-class entities, not spreadsheet tabs.
If you are a CSP chasing a P-ATO and you are writing SSP narratives in Word right now, the gap between where you are and where you need to be is bigger than the calendar will allow. Start by capturing your control inventory in one system with evidence links, then work the writing in parallel with 3PAO prep — not sequentially.
