Find a SOC 2 auditor

SOC 2 auditors, compiled from the public directories we currently observe: Drata and Vanta. Below the guidance is the current list: facts only, alphabetical, never ranked.

How to choose a SOC 2 auditor

You choose your own auditor. A SOC 2 audit is an independent engagement with a licensed CPA firm; it is not assigned by, or tied to, whichever compliance platform you run. The platform collects evidence; the audit is separate.

  • Match the firm to your program, not a ranking. Experience with your framework, your industry, and your company stage matters more than any “top firms” list.
  • Ask who does the fieldwork. The partner who sells the engagement is often not the person who runs it. Ask directly.
  • Get the fee in writing, across tiers. Firm tier (specialist, regional CPA, mid-tier national, Big Four) drives cost more than your headcount. Quote more than one tier.
  • Type 1 vs Type 2. A Type 1 is a point-in-time report; a Type 2 covers a window (commonly 3–12 months). Know which your buyer actually requires before you scope.
  • Confirm independence. The firm that runs your readiness work and the firm that signs your audit opinion may need to be different. Ask.

The audit is a separate cost

The external audit is a separate engagement with a licensed CPA firm, priced independently of any platform. Firm tier drives cost more than your company size does.

  • The platform fee does not include the audit.
  • The audit is a separate engagement with a licensed CPA firm.
  • You choose your own auditor. It is not tied to your platform.
  • Firm tier drives cost more than company size.
