Data quality report card

How complete and consistent NEC's CVE records are, scored across vendor, product, CVSS, and CWE coverage.

A CVE record only requires a description to be published. “Completeness” measures how often NEC also fills in the optional — but extremely useful — fields that make a vulnerability actually actionable: the affected vendor and product, a CVSS severity score, and a CWE weakness type. A higher score means more of this CNA’s CVEs include those details, so defenders spend less time enriching records by hand.
