Most-exploited vendors by KEV, last 90 days (top 15) · security-resilience.ai

Citrix is now among the top 15 vendors by CISA-KEV listings over the last 90 days, after not making that list in the preceding 90. A vendor rising quarter-over-quarter means its exploited footprint is growing right now, not decades ago.

Why it matters

A trailing-90-day view of the most-exploited vendors is the timely version of this signal: it surfaces what attackers are actively working, not a legacy all-time average dominated by long-since-patched software.

What to do

Our take

A vendor climbing the recent exploited list is a leading indicator worth acting on before it is your incident. The timely list is the one whose changes matter.
