How to choose a SOC 2 auditor
Six checks that separate the right firm from the cheapest quote. Run them before you sign anything.
- 01
Start from the buyer's deadline
Work backward from when a customer needs the report. That date dictates whether you need a fast Type 1 now or can run a full Type 2 window.
- 02
Match the firm tier to your stage
A boutique is ideal for a seed-stage startup; a national firm or Big Four may be required if your buyers demand brand recognition. Paying for a tier you don't need is the most common overspend.
- 03
Check framework coverage
If you'll also need ISO 27001, HIPAA, or PCI, a firm that covers them lets you consolidate and reuse evidence instead of running parallel engagements.
- 04
Confirm platform compatibility
If you use Vanta, Drata, or another platform, make sure the auditor pulls evidence from it directly — it removes weeks of manual collection.
- 05
Verify AICPA standing
Only an AICPA-licensed CPA firm can issue a SOC 2 report. Confirm licensure and ask about peer-review history before signing.
- 06
Compare on scope, not just price
The cheapest quote often reflects a narrower scope. Compare what's actually tested and the report's credibility with your buyers, not only the headline number.
