Last updated / Combined scope
This page is for a specific buyer: a govtech SaaS company that has to satisfy the federal government and commercial customers at the same time. FedRAMP authorization, performed by an accredited Third Party Assessment Organization (3PAO), opens the door to selling to federal agencies. A SOC 2 report is what your commercial enterprise buyers expect. Running those two tracks through one firm — a 3PAO that also issues SOC 2 — means a single assessor learns your environment once and applies it to both, instead of two firms duplicating discovery, scoping, and evidence collection.
This is deliberately a narrow, specialist list, distinct from our general SOC 2 ranking. The bare “best SOC 2 auditor” query is a different intent, and our main directory already serves it; what this page answers is the overlap question — which SOC 2-capable firms are also authorized 3PAOs. That authorization is not something a firm can self-declare. A 3PAO is accredited under the FedRAMP program (via A2LA) to assess cloud systems against the federal baselines, and the number of firms that hold that accreditation and also run a CPA SOC 2 practice is small. The registries that list 3PAOs are not SOC 2-aware, and the SOC 2 directories are not FedRAMP-aware; the intersection is what is useful and what nobody else publishes cleanly.
The firms here range from federal-specialist assessors to large national practices that run both federal and commercial compliance under one roof. First-year SOC 2 Type 2 fees among them typically start around $20,000 and run to roughly $35,000 for standard scope; FedRAMP assessment itself is a separate, substantially larger and longer engagement governed by the federal authorization process, not by commercial audit pricing. Treat the SOC 2 figure as the commercial-side cost and budget FedRAMP independently. The advantage of one firm is sequencing: the controls you stand up for FedRAMP's baseline are a superset of much of what SOC 2 expects, so an assessor that knows both can tell you which evidence carries over and stop you from rebuilding the same control documentation twice for two different reviewers.
For how the frameworks compare and when each applies, read the FedRAMP framework page and our government-contractor guidance, linked below; this page is the commercial “which firm does both” answer. Listings are ranked by our published methodology with paid Featured placement labeled as such. Use the quote button to be matched to firms that hold 3PAO authorization and issue SOC 2.

What buyers ask before shortlisting.
These are the questions that usually decide whether a firm belongs on your shortlist.
Yes. The firms on this page are accredited FedRAMP 3PAOs that also run a CPA SOC 2 practice, so one assessor can handle your federal authorization and your commercial SOC 2 report instead of two firms duplicating the work.
Only a small set holds both FedRAMP 3PAO accreditation and a SOC 2 attestation capability — the firms listed here. 3PAO accreditation is granted under the federal program and cannot be self-declared, which keeps the overlap narrow.
No. FedRAMP is a federal authorization to sell cloud services to government agencies, assessed against federal baselines by a 3PAO. SOC 2 is a commercial attestation by a CPA firm. They are separate deliverables for separate buyers.
If you sell to both federal agencies and commercial enterprises, yes — one firm that does both reuses environment knowledge across the two. If you only sell commercially, you likely need SOC 2 alone; FedRAMP is a heavier, federal-specific process.
Use these to pressure-test scope, independence, and cost with any firm you contact from the list.
A Third Party Assessment Organization is a firm accredited under the FedRAMP program to assess cloud service offerings against federal security baselines. Only accredited 3PAOs can perform FedRAMP assessments.
No. FedRAMP assessment is a separate, substantially larger and longer engagement than a commercial SOC 2. Budget the two independently — the SOC 2 fees here do not include FedRAMP work.
Our general directory ranks SOC 2 firms broadly. This page answers a narrower question — which of those firms are also authorized FedRAMP 3PAOs — for buyers who need both.
Use these when you need the broader auditor list, the software angle, or the framework explainer before you choose a firm.
SOC 2 reports require CPA attestation. Preparation software and readiness consultants can collect evidence and reduce audit work, but the opinion has to come from an independent, licensed CPA firm.
Confirm scope in writing. Before signing, ask the firm which report or certificate it can issue directly, which work is handled by an affiliate, and what evidence carries over between frameworks or platforms.
