What this does and does not cover
Holds the ISO 27001 Lead Implementer credential and no other certification. Material on this site covering ISO/IEC 42001, ISO 31000 and SOC 2 is written from published competency domains and the standards themselves, and every claim is sourced on the exam pages — not asserted on the strength of a credential.
Every exam page lists the documents behind its claims, each with a retrieval date.
Background
Director and Principal Consultant at Aegentra, an Australian governance, risk and compliance practice. Ten years implementing management systems inside Microsoft 365 tenants for organisations that have to prove controls work, not just describe them.
Writes the exam references and practice questions here. The sourcing rules here exist because implementation work makes the difference between a documented control and an operating one obvious — and that distinction is exactly what evaluation-level exam questions test.
