What is DevSecOps?

DevSecOps is the DevOps extension that integrates security as a shared responsibility across the entire development and release pipeline, rather than as a separate check run at the end by a dedicated team that approves or blocks downstream. In practice this means dependency scanning, static code analysis and automated security testing run in the same CI/CD steps already used for build, functional testing and deployment, not in a separate phase that slows the release down. The guiding principle is shift left testing: security moves as far upstream in the development cycle as possible, ideally already at the point of writing code and during code review, instead of remaining a final check before production. Finding a vulnerability while the code is being written costs far less than discovering it after release, when the code is already in production and the fix requires an urgent intervention under pressure.

The typical toolset

A mature DevSecOps pipeline combines a few categories of tools that intervene at different points of the release cycle. Dependency scanners spot libraries with already-cataloged known vulnerabilities before they reach production. Static application security testing (SAST) looks for insecure patterns directly in the source code, without needing to run it. Dynamic testing (DAST) instead tests the running application, typically in a staging environment, catching flaws that only surface at runtime. On top of these comes automated secrets management, meant to keep credentials, API keys and tokens from ending up hardcoded in the code or in a configuration file forgotten inside the repository.

The difference from classic DevOps

Classic DevOps automates build, test and deploy to gain speed and reliability in shipping software. DevSecOps adds security as an automated gate in the same pipeline, not as a manual, parallel process run by a separate team that slows down every release while waiting for sign-off. The difference is not just organizational: it changes the moment problems get discovered, from the end of the development cycle to its beginning, where they cost less time and less risk to fix.

Why it matters at the regulatory level too

The Cyber Resilience Act requires security by design across the whole software lifecycle and a documented inventory of dependencies (SBOM): without a DevSecOps pipeline, demonstrating that compliance becomes a manual exercise, slow and hard to repeat at every release. For a company that develops or integrates software, DevSecOps therefore stops being just a technical maturity choice and becomes, in practice, a precondition for meeting regulatory requirements that need checking release after release, not once a year.
