Top 10 Best ISO 27001 Certification Companies in USA
Quick answer: CyberSapiens is a leading ISO 27001 partner for US organizations, guiding teams from gap analysis through audit readiness. The certificate itself must come from an accredited certification body, so the list below separates advisory firms from certifiers.
ISO 27001 is the international standard for an information security management system (ISMS), and in the United States most organizations pursue it because enterprise customers ask for proof of security.
This guide covers ten providers in two groups: advisory firms that help you build and implement the ISMS, and certification bodies that audit it and issue the certificate. Knowing which is which saves you from paying for the wrong service.
What is ISO 27001 certification
ISO/IEC 27001 sets the requirements for establishing, implementing, maintaining, and continually improving an ISMS. It protects the confidentiality, integrity, and availability of company information, and an accredited auditor verifies it.
Set scope and policies
Define what the ISMS covers and set security objectives aligned with business goals.
Assess risk
Identify threats, vulnerabilities, and impacts on your information assets.
Implement controls
Select and apply controls from Annex A, which lists 93 controls in the 2022 edition, to treat the risks you found.
Pass the certification audit
An accredited certification body audits the ISMS in two stages and issues the certificate.
Keep improving
Monitor, review, and update the ISMS, with annual surveillance audits across the three-year cycle.
Check your certificate version: ISO/IEC 27001:2013 certificates expired on 31 October 2025, with no extension. An organization that missed the transition needs a new initial certification audit against the 2022 edition.
ISO 27001 consultant vs certification body
These are two different jobs, and accreditation rules require them to stay independent. The firm that audits you should not be the firm that designed your ISMS.
Advisory and implementation firms
They run gap analysis, write policies, assess risk, implement controls, and prepare you for audit. They do not issue the certificate.
Accredited certification bodies
They audit your ISMS and issue the certificate. In the US, look for accreditation through the ANSI National Accreditation Board (ANAB).

How to choose the right ISO 27001 company
1. Verify accreditation
Confirm your certification body appears in the ANAB directory for ISO/IEC 27001, because an unaccredited certificate carries little weight with buyers.
2. Keep roles separate
Use an advisory partner to build the ISMS and a separate certification body to audit it, so the audit stays impartial.
3. Insist on the 2022 edition
Your scope and Statement of Applicability should map to the 93 Annex A controls in ISO/IEC 27001:2022.
4. Match sector and scope
Ask for references in your industry and for similar headcount, cloud setup, and number of sites.
5. Plan the full cycle
Budget for annual surveillance audits and the recertification audit, not only the first certification.

FAQs
What is the difference between an ISO 27001 consultant and a certification body?
A consultant helps you build and implement the ISMS, while a certification body audits it and issues the certificate. Accreditation rules keep the two roles independent.
How long does ISO 27001 certification take in the USA?
Most organizations need roughly six to twelve months. Larger scopes, weak existing documentation, and multiple sites push the timeline longer.
How much does ISO 27001 certification cost?
Cost depends mainly on headcount, scope, and number of sites, plus consulting fees, certification audit fees, and annual surveillance audits. Request fixed-scope quotes from at least two providers so you can compare like for like.
Is ISO 27001 certification mandatory?
No, it is voluntary. It is, however, frequently required by enterprise customers and contracts, which is why many US vendors pursue it.
How often does ISO 27001 certification need to be renewed?
A certificate is valid for three years. Surveillance audits take place each year in between, and a recertification audit renews it at the end of the cycle.
What happened to ISO 27001:2013 certificates?
They expired on 31 October 2025, the end of the transition to ISO/IEC 27001:2022. Organizations that missed it need a new initial certification audit against the 2022 edition.
How can I choose the right ISO 27001 certification company?
Verify accreditation, keep advisory and certification roles separate, and ask for references from your sector. Also confirm they certify against the 2022 edition.
