Methodology
Rate statistics are arithmetic over published figures: KEV/100 = KEV entries ÷ CVEs × 100; medians are taken over this vendor's disclosures. Vendor names are normalized (case, punctuation, common aliases) before aggregation; monthly counts are keyed to first-seen day, the day this archive first observed the record, not the upstream publication date.
Raw counts are not comparable across vendors: disclosure practices, product breadth, and CNA conventions differ widely, so a larger number here does not mean less secure software. This is a reference page assembled from the public record — not a record of its own, and not a ranking of vendors by our judgment.
Sources. CVE records from the CVE Program (cvelistV5); enrichment from NVD (NIST); known-exploited status from the CISA KEV catalog; exploit probability from FIRST EPSS.
