TL;DR

"Shift left" security wires checks into the SDLC at every stage: threat modelling at planning, SAST and secret scanning in CI, dependency audits at build, DAST/pentests before deploy, and runtime protection in production. Knowing which tool catches which class of issue (SQLi, XSS, hardcoded credentials, insecure deserialization) is what separates a security-aware engineer from one who treats security as someone else's checkbox.
