How to read this: CISA KEV lists vulnerabilities with reliable evidence of exploitation; a vendor with many entries is often one with a large, internet-facing install base, not necessarily worse engineering. "Publication → KEV" is the median number of days between the CVE's publication and its addition to KEV, for entries added in the last 24 months (1 entries); it is an upper bound on how long defenders had, since exploitation usually starts before the listing. Under NIS2 article 21(2)(d), supplier security is part of your risk management; this page is a starting point for that review. Compare vendors on the scorecard index.
We assess supplier security for NIS2 and DORA, from exploited-CVE history and patch response to contract clauses and evidence packs.
