FAQ
Common Questions.
The Known Exploited Vulnerabilities catalog is the US government list of flaws that attackers are using in real attacks. Each entry carries a due date by which federal agencies must patch, which makes it a useful priority list for everyone else too.
Known Exploited holds CVEs with confirmed exploitation. Emerging Threats holds CVEs not on that list yet, but with a high exploit forecast or a weaponized exploit. The Watchlist holds CVEs with a middling publication score that move up when new evidence arrives.
CVSS rates how bad a flaw would be if exploited, on a 0 to 10 scale. EPSS estimates how likely it is to be exploited in the next 30 days. A critical CVSS score with a tiny EPSS can often wait; a high EPSS with a known exploit should not.
CISA sets a remediation due date for every catalog entry. Overdue means that date has passed, so the flaw has been exploitable and listed for longer than the agency deadline allowed.
It shows which products and versions are affected. To know which of your own internet-facing assets run a vulnerable version, the Brandefense platform maps new CVEs against your attack surface continuously.
Which Of These Are On Your Attack Surface?
Brandefense maps every internet-facing asset you own and flags the exploited CVEs on it the hour they are listed.
About this list. Not on the KEV catalog yet, but either the EPSS forecast is 50% or higher or a weaponized exploit exists. The signals say watch it; the evidence does not yet justify a listing.
