No accreditation body accredits ISO 27001 Lead Auditor courses. What the word really attaches to, and the four-step check for whether a course is genuine.

Auditing and implementing are different jobs, and doing both on one ISMS creates an independence problem. How to tell which credential you actually need.

The difference is scope and standing, not seniority. What ISO 27001 requires of internal auditors, and which qualification is worth holding.

IRCA certifies a course and sets its own exam. Exemplar Global certifies the provider, and the provider writes and marks the exam. What that difference means.

CQI IRCA and PECB are not the same kind of credential. What differs in the course, the exam, the grades and the evidence you must show afterwards.

No IT background is required to become an ISO 27001 Lead Auditor. What technical competence an audit does call for, and where a technical expert comes in.

The ISO 27001 Foundation course is not a prerequisite for Lead Auditor and does not count towards certification. An honest test of whether you need it at all.

The ISO 27001 Lead Auditor course has no prerequisites, but it assumes you already know the standard. Exactly what PR373 lists, and how to check you have it.
