Summary

Hide ▲

Analysis of over one billion CISA KEV remediation records spanning four years across 10,000 organizations reveals a systemic failure in enterprise vulnerability remediation despite increased operational effort. Time-to-Exploit has collapsed to negative seven days for critical vulnerabilities, with 88% of tracked weaponized flaws remediated slower than exploitation occurred. Critical vulnerabilities open at Day 7 have risen from 56% to 63% while remediation tickets closed grew 6.5x since 2022. Traditional scan-and-report models cannot close this operational gap as autonomous AI agents accelerate offensive capabilities beyond human response cycles.

    CISA KEV remediation analysis quantifies structural failure in enterprise vulnerability management amid collapsing exploit timelines

    Large-scale analysis of 1,152,000,000 CISA KEV remediation records across 10,000 organizations over four years reveals critical vulnerabilities are now weaponized before patches exist, with 88% of tracked weaponized flaws remediated slower than exploitation occurred. Time-to-Exploit has collapsed to negative seven days while critical vulnerabilities open at Day 7 increased from 56% to 63%. Infrastructure systems face disproportionate exposure, with median remediation times for Cisco IOS XE reaching 232 days compared to endpoint medians under 14 days. Risk Mass and Average Window of Exposure metrics indicate 80% of exposure time stems from pre-disclosure and long-tail patching delays rather than active exploitation phases.
