Frequently asked questions

How is this list sourced?

GovRAMP program participants is the official list, read October 3, 2026. GovRAMP does not endorse or recommend any specific 3PAO. Check the live registry for changes.

Are these listings endorsements?

No. Compare the firm's services and confirm current status before engaging an auditor.

Firms are listed from official registries, each with its own as-of date. Locations are shown only where the registry or the firm's own site provides them. A listing records registry status, not an endorsement, and directory information may change. SOC 2 is a CPA attestation report, not a certificate. pa.tax is independent: listed firms pay nothing for inclusion, ranking or referrals, and firms are listed alphabetically.

Confirm current status and scope directly with the GovRAMP program participants, as of October 3, 2026.
