List Reports
Most scanning tools have options to display a formatted report. Take Grype for example:
grype bkimminich/juice-shop:latest -o table
The report can be printed in a formatted table instead of 6k line JSON file.
JSON can be piped directly into gatecheck for supported reports.
grype bkimminich/juice-shop:latest -o json | gatecheck ls -i grype
Or from an existing report
gatecheck ls grype-scan-report.json
