Cisco vs Nagios
Self-hosted NMS/NPM platforms (carry their own CVEs). Counts are scoped to this segment and the selected published-date window. Cisco carries 1.7× the disclosed CVE volume of Nagios. 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.
