SOC 2 and AI: What It Means for Your Vendors
SOC 2 is an auditing standard published by the AICPA that evaluates how a service organization handles data across security, availability, processing integrity, confidentiality, and privacy. Buyers of AI tools use SOC 2 reports to judge whether a vendor's controls match the sensitivity of data an AI system will process.
01What does a SOC 2 report actually cover?
A SOC 2 report covers five possible trust service categories: security, availability, processing integrity, confidentiality, and privacy. An auditor examines the controls a vendor claims to run and tests whether staff actually follow those controls over a review period, then issues a report with findings.
Security is the mandatory category; a vendor can add the other four depending on the service offered. A company handling AI training data or customer prompts benefits from confidentiality and privacy coverage in addition to security.
02What is the difference between SOC 2 Type I and Type II?
A Type I report checks whether controls are designed correctly at a single point in time. A Type II report checks whether those controls actually operated correctly over a period, usually six to twelve months, based on evidence and testing.
Buyers evaluating an AI vendor should ask for a Type II report where possible, since Type I only confirms a policy exists on paper, not that staff followed it during real operations.
03How does SOC 2 apply specifically to AI systems?
SOC 2 was written before AI systems were common, so no clause names AI directly. Auditors instead map existing categories onto AI specific risks: access controls around training data, logging of model inputs and outputs, and change management for model updates all fall under existing security and processing integrity criteria.
A vendor running a large language model still needs the same access control, encryption, and incident response practices any service organization needs. AI adds new questions about where prompts and outputs are stored and who can view them.
04What should a buyer ask an AI vendor about SOC 2?
A buyer should ask for the current SOC 2 report, the audit period it covers, whether the scope includes the specific product being purchased, and whether any exceptions were noted in the auditor's opinion. A report scoped to one product line does not cover a different product from the same company.
Buyers should also ask how customer data feeds into model training, since SOC 2 alone does not confirm a vendor excludes customer prompts from training a shared model unless that control is explicitly in scope.
05Does Lingows AI hold a SOC 2 certification?
SOC 2 is not a certification; it is an attestation report issued after an independent audit, and no vendor should describe holding a SOC 2 certificate. Lingows AI works with clients to document security practices and to support whatever compliance posture a client's own program requires for a given engagement.
Any specific compliance claim about Lingows AI's own controls should come from current documentation rather than this page, since audit status changes over time.
06SOC 2 trust service categories
| Category | What it covers | Required or optional |
|---|---|---|
| Security | Protection against unauthorized access | Required in every SOC 2 report |
| Availability | System uptime and operational commitments | Optional, added by the vendor |
| Processing integrity | Accurate, complete, timely processing | Optional, added by the vendor |
| Confidentiality | Protection of data designated as confidential | Optional, added by the vendor |
| Privacy | Handling of personal information per stated policy | Optional, added by the vendor |
07Specification
| Field | Detail |
|---|---|
| Typical cost | Vendor audits typically cost the vendor tens of thousands of dollars annually; this is not a cost the buyer pays directly |
| Typical timeline | A Type II audit period commonly runs six to twelve months before a report is issued |
| Prerequisites | Documented policies, access controls, and monitoring already operating before the audit period starts |
| Common failure modes | Buyers assume SOC 2 means a specific product is covered when the report scope is actually a different product or team |
| Who it suits | Buyers evaluating any vendor that stores, processes, or transmits sensitive company or customer data through an AI system |
FAQQuestions
Related questions
Is SOC 2 a legal requirement?
No. SOC 2 is a voluntary attestation. Many enterprise buyers require it in contracts, but no law mandates it directly.
Does SOC 2 guarantee an AI model is safe?
No. SOC 2 evaluates operational controls around data handling, not the accuracy or fairness of a model's outputs.
How often does a vendor need a new SOC 2 report?
Most buyers expect an annual report, since a Type II report only covers a fixed prior period and does not certify future behavior.
Can a small AI vendor skip SOC 2?
A small vendor can skip it, but many enterprise procurement teams will not sign a contract without a current report or a documented plan to obtain one.
