F5 vs HAProxy
L4-L7 load balancers, ADCs and reverse proxies. Counts are scoped to this segment and the selected published-date window. F5 carries 24.6× the disclosed CVE volume of HAProxy. Volume reflects disclosure practice and install base as much as code quality — read it with the severity mix. Sourced from the NIST NVD; lower counts indicate a smaller disclosed vulnerability surface — not necessarily lower risk.
