FAIIR vs. ISO/IEC 42001 vs. SOC 2: Which Fits Your Business?

What is the difference between FAIIR, ISO/IEC 42001, and SOC 2?

The three differ in what they assess: ISO/IEC 42001 assesses an AI management system, SOC 2 assesses security-related controls at a service organization, and FAIIR assesses a smaller business's day-to-day AI governance practices. They come from different issuers, are performed by different kinds of assessors, and produce different outputs.

None is a substitute for the others, and none is a legal compliance certificate. The right choice depends mostly on who is asking for proof and what they want proof of.

What is ISO/IEC 42001?

ISO/IEC 42001:2023 is an international standard that specifies requirements for establishing, implementing, maintaining, and continually improving an artificial intelligence management system (AIMS). It was published in December 2023 by ISO and IEC, and ISO describes it as the world's first AI management system standard.

ISO says the standard is intended for organizations that provide or use products or services that use AI systems, and that it applies to any organization regardless of size, type, or nature. Like other ISO management system standards, it focuses on the organization's system of policies, objectives, risk processes, and continual improvement.

ISO itself does not certify organizations. Certification is carried out by independent certification bodies, which may be accredited by national accreditation bodies. A companion standard, ISO/IEC 42006:2025, sets additional requirements for bodies that audit and certify AI management systems against ISO/IEC 42001.

What is a SOC 2 report?

A SOC 2 report is the result of a CPA's examination of controls at a service organization relevant to security, availability, processing integrity, confidentiality, or privacy. These five categories come from the AICPA's Trust Services Criteria.

Service organizations usually get a SOC 2 report because their customers and business partners ask for one to understand how the vendor's controls are designed and operating. A Type 1 report evaluates controls as of a specific date; a Type 2 report also addresses whether those controls operated effectively over a period. SOC 2 reports are restricted to specified users, unlike SOC 3 reports, which are general-use and less detailed.

SOC 2 is not AI-specific. The Trust Services Criteria are about security and related control objectives over a service organization's system, not about whether an AI tool is fit for its purpose or disclosed to the people it affects.

What is FAIIR?

FAIIR (Foundation of AI Integrity & Regulation) is a private AI governance standard published by FAIIR, LLC for small and midsize businesses that deploy or use AI. It has five pillars and 41 pass/fail controls: Fitness for Purpose (F1–F8), Accountability (A1–A7), Integrity of Data (I1–I9), Informed Use (U1–U7), and Risk Management (R1–R10).

FAIIR certification is annual, firm-specific, and based on evidence the organization submits. It covers an organization's practices around AI, such as its use-case register (F1), acceptable use policy (U1), and incident playbook (R3), not the AI models. It is benchmarked to the NIST AI Risk Management Framework; see NIST AI RMF for small business. The full control list is on the FAIIR framework page.

How do FAIIR, ISO/IEC 42001, and SOC 2 compare?

The table below compares the three on issuer, scope, assessor, output, and fit. Answers reflect each standard's own published descriptions.

Which AI assurance should you choose?

Choose based on who is asking for proof and what they need to see. A short decision guide:

• Choose SOC 2 if you sell software or services and your customers' security or procurement teams are asking for a SOC 2 report. It is the answer to a security question, and an AI-specific standard will not replace it.
• Choose ISO/IEC 42001 if you build or provide AI to large enterprises or international buyers, your customers name the standard in procurement, or you already run ISO management systems and want AI governance inside the same structure. As an international standard, it travels well with buyers outside the U.S.
• Choose FAIIR if you are a small or midsize business that uses or deploys AI, you need to show clients, insurers, or partners a documented standard of care, and you do not have a compliance team to build and maintain a full management system.
• Consider more than one if you are an AI vendor with enterprise customers and also want practical governance controls for how your own staff use AI.

Questions to answer before you commit

1. Who is asking? A customer's security team, an enterprise procurement office, an insurer, and a small-business client each want different evidence. Ask them which credential or document they will accept.
2. What do they want proof of? Security of your systems points to SOC 2. A governed AI program across a larger organization points to ISO/IEC 42001. Responsible day-to-day AI use in a smaller business points to FAIIR.
3. Do you build AI, or use it? Organizations that develop and provide AI products tend to face heavier buyer scrutiny than businesses that use off-the-shelf tools.
4. Who will maintain it? Each option needs an owner after the first assessment. Pick the one your team can actually keep current year to year.

If you are unsure whether a specific law applies to your AI use, that is a legal question. Talk to counsel; FAIIR, LLC does not give legal advice.

Can FAIIR, ISO/IEC 42001, and SOC 2 be layered?

Yes. The three can be layered because each covers different ground. SOC 2 addresses security and related controls over a service organization's system. ISO/IEC 42001 addresses the management system an organization uses to govern AI. FAIIR addresses specific, checkable AI governance practices sized for smaller organizations.

Much of the underlying evidence overlaps. A use-case register (F1), a data classification map (I1), a risk register (R1), and an incident playbook (R3) are useful inputs to any of the three, even though each assessor evaluates them against its own criteria. A common path for a growing business is to start with FAIIR's controls, add SOC 2 when customers begin requesting it, and consider ISO/IEC 42001 when enterprise or international buyers expect it.

Where FAIIR fits

FAIIR is complementary to SOC 2 and ISO/IEC 42001, not a replacement for either, and it is aimed at businesses that need documented proof of reasonable care in their AI use without building a full management system. To see what FAIIR certification covers, read What is FAIIR certification?.
