Security has "shifted left," moving from the final stages of the software development life cycle (SDLC) to a tightly integrated process that's baked in from the beginning. In the old days, security took a backseat to other application development tasks. Scanning tools such as SAST (static analysis security testing) and DAST (dynamic analysis security testing) took a long time and typically ran separately from the continuous integration and continuous delivery (CI/CD) pipelines. Security threats were discovered late in the process, and the main way of fixing them was to apply patches. Automation, integrations, APIs, and other modern security tool capabilities weren't part of the equation.

Then DevSecOps emerged.

DevSecOps integrates security into all stages of the SDLC, making security everyone's responsibility along the entire pipeline. Automation is crucial so that security can keep up with the pace of code development, especially in organizations where developers push multiple times per day. …
