What is Grype and where does it fit in a DevSecOps pipeline?

Describe Grype by the failure it prevents, not by its feature list. It belongs to container and filesystem vulnerability scanning and runs at the image stage of delivery, which matters because the cost of fixing a defect rises sharply the later it is found — the core argument behind shifting security left.

Strong answers cover scanning images, directories and SBOMs, pairing with Syft for SBOM generation, the vulnerability database refresh, --fail-on severity gating, .grype.yaml ignore rules, and comparing results against Trivy. Interviewers also listen for the operational side: who owns the rules, how findings reach the developer who introduced them, how false positives get suppressed without silently disabling coverage, and what the break-glass path is when a fix genuinely cannot ship in time.

Tie it to the wider toolchain. Security scanning is only useful when its output is actionable, deduplicated across tools, and attached to a specific commit, image digest or resource — otherwise teams learn to ignore it.
