PRTG offers robust compatibility across platforms and providers, letting you monitor network devices, servers, operating systems, and applications without worrying about compatibility.
Cisco, Dell, HPE, NetApp. Microsoft Windows, Linux, or Mac operating systems. Wireless networks or LAN, WiFi or Ethernet. PRTG has your back.
Getting started with PRTG is fast and hassle-free. An intuitive setup process, preconfigured sensors, and a user-friendly interface mean you can begin monitoring your network usage within hours.
Whether you're managing a small office, a few remote locations, or a global infrastructure, PRTG minimizes the learning curve and lets you focus on what matters – keeping your network running smoothly. No PhD in rocket science required.
Customization is a paramount feature for network monitoring tools. Out-of-the-box functionality is all well and good, but you also need the ability to tweak settings for your unique IT environment.
Take control of your network with customizable dashboards, notifications, and monitoring templates. Define thresholds for critical network events, visualize trends with detailed graphs, and ensure your team stays focused on what matters most.
PRTG comes with more than 250 native sensor types for monitoring your entire on-premises, cloud, and hybrid cloud environment out of the box. Check out some examples below!
The Packet Sniffer sensor monitors the headers of data packets that pass a local network card using a built-in packet sniffer. You can choose from predefined channels. It can show the following and more:
The SNMP Traffic v2 sensor monitors bandwidth and traffic on a device. It can show the following:
The Ping v2 sensor sends an Internet Control Message Protocol (ICMP) echo request ("ping") from the probe system to the parent device to monitor its availability. It can show the following:
• Response time
• Packet loss
• Target status
• Minimum and maximum ping time
The Port v2 sensor monitors a network service by connecting to one or more of its TCP/IP ports. It can show the following:
See the PRTG Manual for a list of all available sensor types.
Real-time notifications mean faster troubleshooting so that you can act before more serious issues occur.
PRTG is set up in a matter of minutes and can be used on a wide variety of mobile devices.
“Excellent tool for detailed monitoring. Alarms and notifications work greatly. Equipment addition is straight forward and server initial setup is very easy. ...feel safe to purchase it if you intend to monitor a large networking landscape.”

A network activity monitor is a tool that tracks and analyzes all activity within a network. PRTG’s network activity monitor collects data using protocols like SNMP, WMI, SSH, NetFlow, sFlow, and packet sniffing. With visibility into bandwidth utilization, traffic patterns, data usage, device health, and performance metrics, IT teams can maintain network efficiency and security more effectively.
Without a network activity monitor, you risk downtime, bottlenecks, and security threats caused by blind spots in your infrastructure. A network activity monitor identifies those bottlenecks, tracks bandwidth hogs, analyzes traffic patterns, and monitors the health of devices, database metrics, and applications. It proactively sends alerts when issues arise, so your team can quickly resolve problems. PRTG ensures full visibility, enabling you to optimize bandwidth, troubleshoot efficiently, and maintain uptime.
PRTG is designed for simplicity and speed. Its intuitive interface, preconfigured sensors, and automated network discovery mean you can start monitoring within hours – not days – without needing extensive training or resources.
Yes! PRTG supports multi-location monitoring with remote probes and is built to handle complex networks. Whether you’re managing cloud environments, hybrid setups, or global infrastructure, PRTG scales to meet your needs.
PRTG sends real-time notifications via email, SMS, push notification, and other methods, based on thresholds you set. You can also trigger command-line actions or integrate notifications into third-party systems for custom workflows.
In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive. On average, you need about 5-10 sensors per device or one sensor per switch port.
Paessler conducted trials in over 600 IT departments worldwide to tune its network monitoring software closer to the needs of sysadmins. The result of the survey: over 95% of the participants would recommend PRTG – or already have.
Paessler PRTG is used by companies of all sizes. Sysadmins love PRTG because it makes their job a whole lot easier.
Bandwidth, servers, virtual environments, websites, VoIP services – PRTG keeps an eye on your entire network.
