PRTG
PRTG Network Monitor is the most technically deep direct alternative to Auvik for teams that need sensor-level customization and an on-premises deployment option. PRTG's pricing is based on sensor count rather than device count. Each monitored metric (CPU, memory, interface, NetFlow, HTTP) is a separate sensor counted against the license tier, and PRTG publishes pricing tiers starting at 500 sensors. A fully configured PRTG deployment monitoring the same network as Auvik typically costs less in licensing, but requires significantly more setup time: sensors, discovery templates, alert thresholds, and dashboards all require manual configuration. PRTG wins on customization depth, on-premises deployment capability, and lower licensing cost at equivalent scale. Auvik wins on time-to-value and multi-tenant MSP management. Compare PRTG when the team has dedicated network engineering capacity to invest in setup, needs custom SNMP OID monitoring for unusual device types, or requires an on-premises deployment that Auvik cannot provide.
