ISO 42001 vs SOC 2: which does your AI company need?
Short version: SOC 2 proves your security is under control. ISO 42001 proves your AI is governed. If you build or sell AI, buyers increasingly want both — and the good news is the work overlaps.
Side by side
| SOC 2 | ISO/IEC 42001 | |
|---|---|---|
| What it governs | Security & trust controls (the Trust Services Criteria) | An AI Management System — AI-specific risk, fairness, oversight, lifecycle |
| Form | An attestation report (Type I / Type II) from a CPA firm | A certification issued by an accredited body |
| Core focus | Security, availability, confidentiality, processing integrity, privacy | AI risk & impact, transparency, human oversight, data governance |
| What drives the ask | General enterprise security reviews | AI-specific reviews, the EU AI Act, responsible-AI expectations |
| Cadence | Report covering a period; typically renewed annually | 3-year certificate with annual surveillance audits |
Do you need both? Usually, yes.
SOC 2 = baseline trust
It's become table stakes to sell software to enterprises — proof your security, availability and confidentiality controls work.
ISO 42001 = the AI layer
The newer, AI-specific bar buyers and the EU AI Act are starting to require: real AI risk & impact assessments, human oversight, and a governed model lifecycle.
They share a management-system backbone, so the evidence overlaps heavily. Build it once and map it across — don't run two disconnected programs.

DoAIRight stands up and runs your ISO 42001 AI Management System, and its crosswalk maps your evidence to the frameworks your buyers already ask about.
ISO 42001 vs SOC 2 — FAQ
Is ISO 42001 the same as SOC 2?
No. SOC 2 is an AICPA attestation about your security and trust controls; ISO/IEC 42001 is a certifiable standard for an AI Management System — the way you govern the AI you build or use. SOC 2 asks 'are your systems secure?'; ISO 42001 asks 'is your AI governed responsibly?'
Do AI companies need both SOC 2 and ISO 42001?
Increasingly, yes. SOC 2 has become table stakes for selling software to enterprises. ISO 42001 is the newer, AI-specific layer that buyers and the EU AI Act are starting to require of companies that build or deploy AI. If AI is core to your product, you'll likely be asked for both.
Can I reuse SOC 2 work for ISO 42001?
A lot of it, yes. Both are management-system frameworks with shared machinery — governance, risk assessment, access controls, vendor management, change management, evidence. ISO 42001 adds the AI-specific pieces (AI impact assessments, human oversight, model lifecycle). The overlap is exactly why a crosswalk saves you from duplicating effort.
Which should an AI startup do first?
It depends on what your buyers ask for. Many do SOC 2 first because it's widely demanded, then add ISO 42001 as AI-governance questions arrive. But because the evidence overlaps, standing up an ISO 42001 AIMS early makes both easier — and DoAIRight maps your AIMS to SOC 2, the EU AI Act, NIST AI RMF and ISO 27001 so you build once and reuse.
Is ISO 42001 a certification or an attestation?
A certification — issued by an accredited third-party certification body after a two-stage audit. SOC 2 is an attestation report signed by a CPA firm. Different mechanisms, but both are third-party validation you can show customers.
