 2. Tools for scanning known component lists in various formats, including .csv, several linux distribution package lists, language specific package scanners and several Software Bill of Materials (SBOM) formats.
 
 It is intended to be used as part of your continuous integration system to enable regular vulnerability scanning and give you early warning of known issues in your supply chain.
