How we compared these firms
We looked at what each firm publicly says about:
- The ISO 42001 services it offers (readiness, implementation, audit support or assessment)
- Who issues the final certificate or report
- The other frameworks it supports
- Where it is based and who it serves
- Anything distinctive it publishes, such as pricing, accreditations or specialisms
We don't rank the firms by score. The right choice depends on your scope, industry, budget and what your customers ask for.

Where CyberWave GRC fits
We're a good fit if ISO 42001 sits next to ISO 27001, SOC 2 or a privacy law in your plans. We treat your existing ISMS as the foundation, add the AI-specific pieces (AI risk and impact assessment, model and data lifecycle controls, AI supplier oversight) and take you through to the certification audit. If you only want templates to run the project yourself, a documentation-kit provider will cost less, and we'll tell you so.
How to choose
- Who will issue the certificate, and is that body accredited for ISO 42001?
- Can the firm build on your ISO 27001 management system?
- Does it have real AI risk and impact assessment experience?
- Will it cover AI suppliers and third-party models you use?
- Does it also cover the EU AI Act or India's DPDP Act if they apply to you?
- What timeline does it commit to, and what does it need from your team?
- Is the fee fixed, and is the certification body's fee included?
Frequently asked questions
ISO/IEC 42001 is the international standard for an AI management system (AIMS). It sets requirements for governing how an organisation develops, provides or uses AI, including risk and impact assessment.
An accredited certification body. Consultants help you prepare but should never certify their own work.
It depends on scope and maturity. Firms in this guide quote anything from a few months to over a year. Companies with ISO 27001 already in place usually move faster. See our ISO 42001 cost and timeline guide.
No, but it helps. Both use the same management system structure, so ISO 27001 gives you risk management, internal audit and management review processes you can reuse.
It can support it. ISO 42001 gives you governance and risk processes that align with many EU AI Act expectations, but it is not a substitute for meeting the Act's specific legal requirements.
