Choosing a network monitoring tool comes down to four questions: how much it costs, how hard it is to run, how far it scales, and what support you get. Here is how the four most popular options compare.

How to read it
- SolarWinds is the most feature-complete for large, multi-team enterprises that can fund it.
- PRTG is the quickest to get value from for small and mid-size organisations; its sensor licensing is simple to budget.
- Zabbix matches much of the commercial capability at no licence cost — ideal if you have (or can hire) the skills.
- LibreNMS shines when your priority is fast auto-discovery and clean dashboards for routers and switches.
Our recommendation
- Small business: PRTG (easy) or LibreNMS (free).
- Growing mid-market: Zabbix for capability without licence cost.
- Large enterprise / regulated: SolarWinds or a well-engineered Zabbix deployment.
