What is DevSecOps?

Understanding DevSecOps

DevSecOps represents a fundamental shift in how we approach security—instead of treating it as a final checkpoint at the end of development, it embeds security throughout the entire software development lifecycle. In traditional models, security teams were often seen as the 'department of no' that slowed things down, checking for vulnerabilities just before deployment when fixes were expensive and disruptive. DevSecOps flips this model by making security everyone's responsibility and automating security checks at every stage of development. Developers get trained in secure coding practices, automated scans run with every code commit, and infrastructure is defined as code that includes security controls by default. The goal isn't perfect security (which doesn't exist), but rather finding and fixing security issues when they're still small and inexpensive to address. Organizations that implement DevSecOps effectively typically see fewer security incidents and faster recovery when problems do occur.
