Paessler PRTG Network Monitor

PRTG is widely favored for its approachable setup and flexible sensor-based licensing. It acts as an all-in-one solution that covers network traffic, bandwidth, and device health using protocols like SNMP, WMI, and NetFlow. The platform is known for its 'Map Designer,' which allows users to create high-level dashboards with real-time status icons. Because it includes a free tier for up to 100 sensors, it is a staple for SMBs, while its high-end Enterprise plans support massive infrastructures with thousands of devices.
