Routing & Switching · head-to-head

Cisco vs Juniper

Enterprise and data-center routers plus Ethernet switching. Counts are scoped to this segment and the selected published-date window. Juniper carries 2.1× the disclosed CVE volume of Cisco. 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.
