Each tool entry details what it scans, which vulnerability classes it detects, CI/CD integration options, and coverage boundaries. The post also covers how to select tools based on your stack, how to integrate them into the SDLC following NIST SP 800-218 controls, and how cloud context (CSPM/CIEM) fills the gap that code-layer tools leave around runtime exploitability and infrastructure risk. ## Full article daily.dev links to this article rather than hosting it.
