Prometheus vs Zabbix
Security track record, side by side · Prometheus · Zabbix
On tracked security data, Prometheus currently has the cleaner record — fewer exploited and high-severity CVEs than Zabbix. That reflects history, not a guarantee: always check the exact version you run.
Health score (latest supported)iOur 0–100 score for the newest supported release — higher is healthier. 81/100 100/100✓
Known CVEs (all time)iTotal tracked CVEs ever recorded. A larger, older, more-scrutinised project tends to have more — context, not a verdict. 3 115

How to read this. This compares historical vulnerability track record from NVD and CISA KEV — not code quality, config, or your deployment. A higher CVE count often reflects a larger codebase, longer history and more security research, not necessarily weaker software. The decisive security question is the version you run — so check it.
