Can my SOC 2 auditor also do my penetration test?
Usually no. Under AICPA independence rules, the CPA firm that audits your controls cannot design or operate them, and a penetration test it then relies on can compromise that independence. Use a separate provider for the pentest.
The full answer
Usually no, and the reason is independence. Under AICPA rules, an attestation firm cannot design or operate the controls it audits; it cannot perform management functions for the client. A penetration test is often part of your security control set, so if the same firm both runs the pentest and then audits how you handle its findings, it risks auditing its own work.
This is why audit work and remediation or testing work are commonly separated. Many buyers use one provider for penetration testing and vulnerability management and a different, independent CPA firm for the SOC 2 attestation. Keeping them apart avoids awkward conversations later when an enterprise customer's vendor-risk team asks whether your auditor was truly independent.
There are nuances. Some larger firms have separate practice lines and use safeguards, and a pentest performed by an unrelated third party can simply be provided to the auditor as evidence. The cleanest path, though, is to commission the penetration test independently and hand the report to your auditor rather than buying both from one shop.
Practically, plan for two line items: an independent penetration test and the SOC 2 audit itself. Audits booked through the AuditNex network start at $2,500 and average about $5,000, while a typical US SOC 2 audit runs $5,000 to $60,000 or more depending on scope, per Vanta, Drata, and Secureframe pricing guides. Confirm independence with any auditor before you sign.

Related questions
Are cheap SOC 2 audits legit?
Sometimes. A low price is legitimate only if a licensed CPA firm issues the report under SSAE No. 18. Suspiciously cheap 'audits' that skip fieldwork, use non-CPA reviewers, or auto-generate reports are not real SOC 2 attestations.
Can my SOC 2 auditor help me remediate issues they find?
Not directly. Under AICPA independence rules your attestation firm cannot design or operate the controls it audits, so it cannot fix your gaps. It can flag deficiencies, but remediation must come from you or a separate advisor.
Do I need a local SOC 2 auditor?
No. SOC 2 audits run remotely, so your auditor's location rarely matters. What matters is that a licensed CPA firm signs the report under SSAE No. 18. Time-zone overlap and industry experience help more than being in your city.
Does my SOC 2 auditor need to be a CPA firm?
Yes. A SOC 2 report is an AICPA attestation issued under SSAE No. 18, so it must be signed by a licensed CPA firm. Readiness prep can come from anyone, but only a CPA firm can issue the report.
Does the auditor's brand name matter to enterprise buyers?
Less than founders expect. Most enterprise buyers accept any SOC 2 report signed by a licensed CPA firm; they check the scope, opinion, and exceptions, not the auditor's logo. A recognizable name can smooth procurement but seldom decides it.
How do I choose a SOC 2 auditor?
Choose a licensed CPA firm (SOC 2 is a CPA attestation), check its current AICPA peer review, confirm experience with your industry and stack, and compare fixed quotes. AuditNex network audits start at $2,500 and average about $5,000.
