Udemy's ISO 27001:2022 Lead Auditor: ISMS Audit Step by Step is a widely taken option: nearly seven hours of video, a 4.4-star rating from 1,953 ratings, over 11,700 students, and an update in June 2026. For understanding how an ISMS audit actually runs, from planning to closing, it's affordable and practical.
The listing doesn't name PECB, so you'll need to check its fit against the current 80-question exam yourself. Udemy has no platform-level diagnostic or readiness score for individual learners.
Edureify starts with a diagnostic across audit execution, audit principles and ISMS fundamentals, then builds a day-by-day plan around the 22.5% conducting-an-audit domain if that's your gap. The Readiness Score tracks you toward 70%.
