What is the ISO/IEC 27001 Lead Auditor certification and what does it qualify you to do?

The ISO/IEC 27001 Lead Auditor certification qualifies professionals to plan, conduct, and lead audits of an Information Security Management System against ISO/IEC 27001:2022. It confirms competence in certification, internal, and supplier audits using ISO 19011 and ISO/IEC 17021-1 requirements.

What is the difference between ISO 27001 Lead Auditor and Lead Implementer?

ISO 27001 Lead Auditor focuses on auditing and certification of an ISMS, while Lead Implementer focuses on designing and deploying an ISMS. Auditors assess conformity and effectiveness; Implementers build and operate the system.

““When the same person tries to implement and audit, objectivity disappears. Certification bodies notice this immediately.””
