Unlike many competitors that charge per device, PRTG uses a "sensor" model. A sensor is a monitoring unit that tracks a specific metric on a device (e.g., CPU load on a server, traffic on a switch port, or availability of a website). This modular approach allows for highly granular monitoring and avoids hidden costs for different types of sensors, as access to all sensor types is included in the subscription.

Using a modified or cracked version of PRTG poses a massive security risk, potentially introducing malware or backdoors into your core enterprise environment. Always use official keys. 4.
