“Shifting (security)” left approach in Software Development Life Cycle (SDLC) means starting security earlier in the process. As organizations realized that software never comes out perfectly and are riddled with many exploitable holes, bugs, and business logic vulnerabilities that require going back to fix and patch, they understood that building secure software requires incorporating and consolidating numerous resources.
