The cyber security skills gap is a global problem, but it is acutely felt in South Africa, where access to structured, affordable, and locally relevant training remains limited. This talk draws on first-hand experience designing and building Capture the Flag (CTF) challenges for the SANReN Cyber Security Challenge (CSC) to explore how individuals and small groups can become the spark that ignites a local security community. From identifying the gap to building beginner-friendly challenges, running competitions, and watching participants grow into contributors. The SANReN CSC was created with the sole purpose of building up local cyber security skills but we would like to extend that goal by supporting local communities to start up their own initiatives and hacking communities.
