Compare by stage

The right auditor depends on your stage

A 12-person startup and a 2,000-person enterprise should not hire the same firm. We've grouped the directory by buyer stage, with planning-range pricing for each.

Startups

First SOC 2, small team, price-sensitive. Boutique firms with low planning ranges and fast fieldwork.

Growth-stage teams

Series A to mid-market. Credible reports for bigger customers, with ISO/PCI/HITRUST runway.

Enterprise buyers

Regulated, multi-entity, or multi-framework programs — or a stakeholder that requires a Big Four name.

Common questions

SOC 2 basics

What is a SOC 2 Type 2 report?

A SOC 2 Type 2 report is an independent auditor's opinion — issued by a licensed CPA firm under AICPA standards — on whether your security controls were suitably designed and operated effectively over a review period, usually 6 to 12 months. It covers the Trust Services Criteria you select (Security is mandatory; Availability, Processing Integrity, Confidentiality, and Privacy are optional).

How much does a SOC 2 Type 2 audit cost?

Published ranges put the audit fee between $7,000 and $100,000 depending on company size and scope, with first-year all-in costs (readiness, tooling, staff time) of $30,000 to $150,000 in published 2026 sources. See our cost guide and the 2026 pricing report for sourced numbers.

How long does a SOC 2 Type 2 audit take?

End to end, 9 to 15 months for a first audit: 1 to 3 months of readiness work, a 3 to 12 month observation period, and 4 to 8 weeks for the auditor to issue the report. See the timeline.

Who can issue a SOC 2 report?

Only a licensed CPA firm can issue a SOC 2 report under AICPA attestation standards. Compliance software can prepare you, but it cannot sign the report.
