How these numbers are made

CISA KEV counts use the full catalogue, refreshed every 10 minutes. CVEs in coverage are those recorded by CyberSIXT. BOD 22-01 deadlines bind US federal civilian agencies.

CVEs with FIRST EPSS at or above the 95th percentile (top 5%), excluding CVEs in CISA KEV. EPSS estimates exploitation probability over the next 30 days.

Coverage is above its usual rate at three or more articles in 7 days and at least 2.5 times the weekly mean of the preceding 8 weeks.

Product names are grouped by normalised names, with version and edition tails removed.

Fix listed refers to an advisory. Unknown fix status is counted as not listed.
