PRTG licenses are based on the number of sensors, where each monitored metric (e.g., CPU load on a server, bandwidth on an interface) consumes one sensor from the license count. ### Does PRTG support cloud monitoring? Yes. PRTG includes sensors for AWS, Azure, and other cloud services, and is also available as PRTG Hosted Monitor in a fully cloud-hosted configuration. ### Is PRTG suitable for small businesses? Yes. PRTG offers a free tier for up to 100 sensors and scales to enterprise deployments, making it accessible to organizations of all sizes. ### What is PRTG Network Monitor and how does it work? PRTG Network Monitor, made by Paessler AG, is a comprehensive network and infrastructure monitoring solution that uses sensors to monitor every aspect of IT infrastructure including networks, servers, applications, and cloud services. Each sensor monitors one specific aspect of a device (e.g., CPU usage, bandwidth on an interface, response time of a website), and PRTG's licensing is based on the number of active sensors. ### What protocols does PRTG support for network monitoring? PRTG supports a wide range of monitoring protocols including SNMP (v1, v2c, v3), WMI, SSH, REST APIs, Ping, HTTP/S, FTP, DNS, and many application-specific protocols. This broad protocol support enables PRTG to monitor virtually any network device or application that exposes monitoring data, from network switches to web servers to business applications. ### What is PRTG's licensing model? PRTG is licensed based on the number of monitoring sensors (data points) active in a deployment. Free versions are available for small environments (up to 100 sensors), with commercial licenses for larger environments scaling up to unlimited sensors for enterprise deployments. The sensor-based model allows organizations to pay proportionally to their monitoring scope. ### Does PRTG offer a cloud-hosted option? Yes, Paessler offers PRTG Hosted Monitor, a cloud-hosted SaaS version of PRTG that eliminates the need to manage monitoring server infrastructure on-premise. PRTG is also available as a traditional on-premise software deployment, giving organizations the choice of deployment model that best fits their security and infrastructure requirements. ### What is PRTG's geographic market strength?
