How to Compare SOC 2 Auditors
Use the filters above to narrow the list, then open individual profiles to review specifics. Here is what to prioritize as you compare.
Industry alignment
Auditors who work with companies in your industry will understand your typical control environment, data flows, and regulatory context. Filter by industry above or browse the industry pages for dedicated listings.
Company size and stage
A seed-stage startup getting its first SOC 2 report needs a different engagement model than an enterprise renewing a Type II. Filter by company size to find firms that focus on your stage.
Platform experience
If your team uses a compliance platform like Drata, Vanta, Secureframe, Sprinto, Thoropass, or Hyperproof, an auditor familiar with that tool can speed up evidence review. Filter by platform to surface experienced firms.
Pricing and timeline clarity
Review each firm's profile for available pricing and timeline data. Not all firms publish this information publicly, so expect to request quotes from your shortlist of 2 to 4 firms.
What to Look for in a SOC 2 Firm
- 1Understand the firm type. Only licensed CPA firms can issue SOC 2 reports. Readiness partners help you prepare but do not issue the final report. If you need the report, verify CPA licensure with the relevant state board.
- 2Relevant experience. Ask how many SOC 2 audits the firm completes annually and whether they regularly serve companies like yours.
- 3Clear communication. The audit process involves sustained back-and-forth. Ask about the firm's communication cadence, project management approach, and typical point of contact.
- 4Transparent pricing. Ask whether pricing is fixed-fee or time-and-materials, what is included, and whether readiness or remediation support is available.
- 5Realistic timelines. Get written estimates for readiness assessment, observation period, fieldwork, and report delivery before signing an engagement letter.
Questions to Ask Before Choosing an Auditor
Once you have a shortlist, use these questions during introductory calls to evaluate each firm.
- How many SOC 2 audits does your firm complete each year?
- Do you have experience with companies in my industry?
- Have you worked with my compliance platform before?
- Is your pricing fixed-fee or time-and-materials?
- What is included in the engagement (readiness, remediation, etc.)?
- What is the expected timeline from kickoff to final report?
- Who will be my primary point of contact during the audit?
- Can you share a sample report or engagement letter?
Frequently Asked Questions
- How do I compare SOC 2 audit firms?
- Start by filtering firms by industry, company size, and compliance platform. Then review individual profiles for audit types offered, pricing structure, typical timeline, and platform experience. Shortlist 2 to 4 firms and request proposals or introductory calls before making a decision.
- What should I look for in a SOC 2 auditor?
- Verify the firm holds a valid CPA license. Ask about their experience with your industry, company size, and compliance platform. Clarify whether pricing is fixed-fee or time-and-materials. Request a written timeline covering readiness, observation, fieldwork, and report delivery.
- How many SOC 2 auditors should I evaluate?
- Most buyers benefit from comparing 2 to 4 firms. This gives you enough options to evaluate pricing, timeline, and communication style without making the process unnecessarily long.
- Does it matter if a SOC 2 auditor knows my compliance platform?
- Yes. Auditors familiar with your platform (Drata, Vanta, Secureframe, Sprinto, Thoropass, Hyperproof) can navigate evidence rooms and automated controls more efficiently, which reduces back-and-forth and can shorten the overall audit timeline.
