Active commits do not prove fresh advisory data. Check the code and the data feed separately, and use a recent known advisory to test how fresh results are.
Short, sourced answers to common questions about scanner output: fixed versions, ranges, aliases, severity bands, EPSS, SARIF fields and VEX statuses.
When a scanner lacks support for your language or package manager, you still have options: SBOM import, a manual inventory, or a second tool.
Copy this one page scorecard for a vulnerability scanner demo: eight criteria, a simple 0 to 2 scale, evidence notes, and rules for adding up the result.
Before comparing scanners, match dev dependencies, transitive resolution, ignore paths and severity filters, so defaults do not skew the result.
A scanner comparison sheet works when every row has the same fields. Here are the columns for findings, repositories and runs, with a short example.
When a scanner cannot name or version a component, it cannot match it to advisories. See how unidentified items hide risk and how to surface them.
