HAProxy vs Progress (Kemp LoadMaster)
L4-L7 load balancers, ADCs and reverse proxies. Counts are scoped to this segment and the selected published-date window. Progress (Kemp LoadMaster) carries 2.0× the disclosed CVE volume of HAProxy. Volume reflects disclosure practice and install base as much as code quality — read it with the severity mix.
