Frequently Asked Questions

What is DevSecOps?
DevSecOps integrates security practices into every phase of the DevOps lifecycle. Instead of security being a final gate, it is embedded in development (SAST), CI/CD (image scanning), deployment (policy enforcement), and runtime (monitoring).
What does shift-left security mean?
Shift-left means moving security testing earlier in the development lifecycle. Instead of finding vulnerabilities in production, you catch them during coding (IDE plugins), pull requests (automated scans), and CI pipelines (SAST/SCA).
What tools do I need for DevSecOps?
A minimal DevSecOps toolchain includes: a SAST scanner (Semgrep, SonarQube), a dependency scanner (Snyk, Dependabot), a container scanner (Trivy, Grype), and a policy engine (OPA, Kyverno). Start with one per category and expand.
