Most security teams think running a scanner means they're protected. It doesn't. Scanning finds vulnerabilities after packages have already arrived — it doesn't block risky dependencies at the door, tell you whether a vulnerable code path is actually reachable, or alert you when a CVE disclosed yesterday is running in production right now.
This track builds the full security stack: block threats before they enter, prioritize what actually matters, and maintain visibility from code to runtime. Work through the sections in order, or jump to the one that matches your most urgent gap.
