Study guides

Every one of these is a cert I sat myself, written from the notes I actually used. What is on the exam, how the questions are worded, and how I planned the study time. Free, always.

The cert that made me a better engineer, not just a better manager. What GSTRT tests, how to build the index that passes it, and why the "soft" cert is the hard one.

The hardest AWS security exam, domain by domain: detection and response, logging, infrastructure, IAM, data protection and governance — plus the service comparisons it tests relentlessly.

CySA+ is Security+ with the training wheels off: real log analysis, real vulnerability prioritisation, real incident response. Here is what it tests and how to prepare.

Everything Security+ actually tests, domain by domain, with a six-week study plan and the question patterns that catch people out.

GCIH is open book, and that is exactly why people fail it. How to build the index that passes the exam, plus every attack technique and incident handling phase it tests.

The fastest useful AWS certification. Every domain, the services that actually appear, the pricing and support models people lose marks on, and a three-week plan.
