Summary
LinkedIn has significantly enhanced its static application security testing (SAST) capabilities by re-engineering its pipeline using GitHub Actions and custom workflows. This overhaul allows for consistent and enforceable code scanning across its extensive repository base, leading to improved security coverage, a more streamlined developer experience, and better observability. This initiative aligns with LinkedIn's broader strategy of integrating security earlier in the development lifecycle, known as 'shift-left'.
