In my opinion, the biggest benefit of Security as Code in DevSecOps is continuous security enforcement, because it integrates security practices directly into the software development lifecycle rather than treating them as a separate or final-stage activity. By embedding automated security checks, policy enforcement, and vulnerability scanning into CI/CD pipelines and infrastructure code, organizations can consistently apply security standards across applications and environments. This approach helps teams detect vulnerabilities earlier, improve compliance with regulatory requirements, and reduce human error while maintaining development speed. Additionally, Security as Code strengthens collaboration between development, operations, and security teams by making security a shared and continuous responsibility throughout the development process.
