About
FedRAMPAssessors exists to make it faster to shortlist a FedRAMP 3PAO. That's the whole mission — no more, no less.
FedRAMPAssessors is a directory of the 48 independent assessors (3PAOs) currently recognized to perform FedRAMP security assessments. Every firm, impact level, accreditation date, and framework tag on this site comes from the official FedRAMP Marketplace assessor export — the same data source FedRAMP itself publishes — not from manual research, guesswork, or paid submissions.
We are not affiliated with GSA, the FedRAMP PMO, or any assessment organization listed here. We don't grant, verify, or influence FedRAMP recognition status — that's the FedRAMP PMO's role, working with A2LA accreditation. We're a reference layer on top of public data, meant to save you the trouble of parsing a government export file yourself.
Where this site highlights "top" or "most active" assessors, that ranking is computed purely from current assessment volume in the source data — the number of cloud service offerings (CSOs) a firm is actively assessing. We don't have a pricing or referral relationship with any firm listed here, and no firm can pay to rank higher or appear more prominently.
The current dataset was pulled from the FedRAMP Marketplace on 2026-08-18. FedRAMP recognition status, active engagement counts, and impact levels change over time as firms are newly recognized, complete assessments, or wind down. Always confirm current status on the official FedRAMP Marketplace before making an engagement decision.
If you're one of the firms listed here and something is out of date or incorrect, see the For Assessors page for how to flag it.
