173 firms SOC 2 Auditor Firms.

Filter by company size, industry, budget, and AICPA peer-review status. Firm-stated size markets are authoritative; where a firm has not stated them, the directory labels a price-based compatibility estimate. The three organization groups have dataset-derived Type 2 planning bands: assurance specialist $16K–$50K, full-service CPA $30K–$80K, and Big Four $60K–$200K. Organization group is not a quality score. Pass with Deficiencies is not Pass, and a missing public rating is not a Fail. See /soc-2-audit-cost/sources/ for how each range is calculated.

It means our research team has checked the firm against public records: that it operates under the listed name, that it's a licensed CPA firm able to issue SOC 2 reports, and — for US firms — that we located its AICPA peer-review record. Each firm carries trust badges showing exactly which of these we confirmed, and the date we last checked. Where we could not confirm something, the firm stays listed with a caveat badge rather than being hidden. We re-check periodically.

Pricing ranges come from direct outreach to each firm and interviews with their clients. Ranges are refreshed quarterly and tagged with a last-verified date.
