Why we included this project

Omar Santos has spent years turning his books, video courses, and live training into this reference collection, and it shows in how the material is organized. Instead of a flat pile of links, you get a domain taxonomy that separates offensive security, defensive work, cloud and container security, and AI security, so a beginner can find a sensible path and a working professional can jump straight to a specific topic. The AI section covers LLM engineering, AI-assisted incident response, and AI security, which matters given how fast that area moves. Certification roadmaps for Cisco, cloud, Kubernetes, CompTIA, and ISC2 exams sit apart from the broader material, which makes exam prep less of a scavenger hunt. Because this is a curated index rather than software you install, treat it as a map: pick a domain, follow the links to tools and labs, and build your own practice environment.
