Two plain-English handbooks, two free tools and a growing library of articles. All written by the people who teach the courses and build the tools.
Handbook
The 14 cyber security artefacts, one chapter each. What the artefact is for, what the regulator expects to read in it, where people go wrong, and how it links to the next one. Written for engineers who have been handed a DO-326A requirement and need to know what good looks like.
Handbook
What the CAA asks for in a UK SORA application, and why. From working out your SAIL to what Phase 1 and Phase 2 actually involve, the CAA charges, and the mitigations that bring your SAIL down. Written for operators, not regulators.
