We spent a good chunk of late May 2025 building a short course on Nmap from scratch - 12 lectures, 12 companion labs, plus the entire virtual lab infrastructure the students would use to run the labs. The whole thing lives on our wiki under Nmap/Short Course.
This post is not about the Nmap material itself (that comes in the next post). It is about the design decisions behind the course - why 12 lectures, why a fully isolated cloud lab, why Vagrant + Docker + Ansible instead of picking one, and what we would do differently if we started over.
