FedRAMP Rev 5 FedRAMP-3PAO: 3PAO Assessment, FedRAMP Marketplace and Accreditation

Third Party Assessment Organizations (3PAOs) are independent assessors accredited by the FedRAMP PMO + A2LA (American Association for Laboratory Accreditation). 3PAO accreditation requires: (a) ISO/IEC 17020:2012 compliance for inspection bodies; (b) FedRAMP-specific training + experience; (c) FedRAMP PMO + A2LA review + accreditation. 3PAOs conduct: initial assessment for FedRAMP authorization + annual ConMon assessments + assessment for significant changes + 3-year full re-assessment. Output: SAR + supporting evidence + recommendations. FEDRAMP MARKETPLACE is the public-facing FedRAMP authorization listing at marketplace.fedramp.gov - lists CSPs by authorization status (In Process + JAB Authorized + Agency Authorized + Ready) + baseline + agency sponsorship + 3PAO + FedRAMP impact level. CSPs achieve 'FedRAMP Ready' status (3PAO Readiness Assessment Report indicating likelihood of authorization) + 'In Process' (active authorization workflow) + 'JAB Authorized' or 'Agency Authorized' (achieved authorization). The Marketplace is updated quarterly + reflects authorization status + significant changes.
