Why Use GitHub Actions for Security?

Shift-left security:

detect vulnerabilities early, as part of the CI pipeline.

SAST automation:

run Semgrep, SonarQube, CodeQL, Bandit, ESLint-security.

DAST automation:

use OWASP ZAP to scan running applications.

Dependency scanning:

check for vulnerable libraries using Dependabot.

Policy enforcement:

automatically fail builds when High/Critical findings appear.

SARIF integration:

results are shown in the GitHub Security → Code Scanning

Alerts dashboard.

Using GitHub Actions allows teams to create

repeatable, auditable, and enforceable DevSecOps pipelines with zero local setup.
