Cisco vs Nagios

Self-hosted NMS/NPM platforms (carry their own CVEs). Counts are scoped to this segment and the selected published-date window. Nagios carries 1.4× 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.
