Why is "Shift Left" security important in DevSecOps?

Shift Left" security is essential in DevSecOps because it emphasizes integrating security practices early in the software development lifecycle. Instead of waiting until deployment or production to test for vulnerabilities, developers use tools and automated checks during coding and integration phases. This proactive approach reduces risks, shortens remediation time, and saves costs associated with late-stage security fixes. Any DevSecOps tutorial will stress that early detection leads to more secure, resilient applications. By embedding security into development from the start, organizations can build a culture of continuous, integrated security without slowing down delivery.
