DevSecOps
DevSecOps means building security checks directly into the CI/CD pipeline — dependency scanning, static analysis, secret detection — so vulnerabilities are caught before merge, instead of security being a separate review that happens right before (or after) release.
“Shift left” is the phrase usually attached to DevSecOps — moving security checks earlier in the development process, where they’re cheaper and faster to fix, rather than treating security as a gate right before a release ships. In practice this means static application security testing (SAST) and dependency vulnerability scanning run automatically on every pull request, secret-scanning blocks a commit that accidentally includes an API key, and container images are scanned for known CVEs before they’re allowed to deploy.
The organizational shift matters as much as the tooling: instead of a separate security team reviewing a finished feature (and becoming a bottleneck everyone resents), engineers see security findings in the same pull request as their code review comments, at the point where fixing them is a five-minute change instead of a production incident.
Done well, DevSecOps doesn’t slow releases down — it catches the kind of issues that would otherwise turn into an emergency patch weeks after the code shipped.
