Nagios vs Paessler
Self-hosted NMS/NPM platforms (carry their own CVEs). Counts are scoped to this segment and the selected published-date window. Nagios carries 23.3× the disclosed CVE volume of Paessler. 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.
