SOC 2 audit cost calculator for AI companies (2026)

For an 11-50 person AI company running LLMs on customer data, a first-year SOC 2 Type 2 audit typically runs $20K-$45K in CPA-firm fees, plus $12K-$22K for a GRC platform (Vanta, Drata, Secureframe), plus $8K-$18K for a gap assessment. Year-one total lands around $40K-$85K excluding internal labor.

Type 1 is a point-in-time attestation on the design of your controls. Type 2 tests operating effectiveness over a 6-12 month observation window. Type 1 is cheaper and faster, but most enterprise customers require Type 2. A common path is Type 1 in month 3-6, then Type 2 spanning the next 6-12 months.

Three reasons: (1) auditors ask more questions about model-access controls, prompt-injection defenses, and output monitoring; (2) if you train models on customer data, the auditor must verify data-lineage and training-set segregation controls; (3) AI-specific control tests are new enough that auditors bake more hours into their estimates. Expect 8-30% higher audit fees than a non-AI peer.

They serve different buyers. SOC 2 is the North American enterprise-procurement standard. ISO 42001 is the international AI-specific management-system standard. If you sell to US enterprises, SOC 2 is table stakes. If you sell to EU or global enterprises, ISO 42001 (or ISO 27001) matters more. Many companies eventually carry both.

Security is mandatory. Availability is standard for SaaS. Confidentiality is standard for anyone handling customer data. Privacy is worth adding if you handle US consumer PII or EU personal data. Processing Integrity is generally optional. AI companies most commonly scope Security + Availability + Confidentiality.

Marginally. GRC platforms cut internal labor and shorten the audit by streamlining evidence collection. Auditors typically discount 5-15% for auditor-integrated automation. The bigger savings are in your team’s time, not the audit fee.

A gap assessment is a pre-audit review by a CPA firm or consultant to identify controls that will fail the audit. It typically runs $8K-$70K depending on company size. Skip it only if you have run a SOC 2 before or your GRC platform runs a robust internal readiness check.

Minimum 3 months (rare, weak-signal), typical 6 months for first-year, standard 12 months for ongoing. Most first-year Type 2 reports use a 6-month window to reach a report faster.

Policy drafting, control-mapping to TSC criteria, evidence-collection setup, internal-audit dry run, and remediation of gaps identified in the gap assessment. Ranges from $15K (small, mature) to $220K (500+ employees, greenfield).

AI-specific controls typically cover: model-registry and versioning, training-data governance and lineage, prompt-injection and output-monitoring for hosted LLMs, DLP for LLM API calls, model-access controls (who can call what model with what data), and change-management for model updates. Most fit under existing TSC categories but expand the scope of testing.
