Custom alerts and data visualization let you quickly identify and prevent bandwidth bottlenecks.
Implementing proper bandwidth control helps prevent network congestion and ensures critical applications have the resources they need. Without good bandwidth management, your network might slow down to a crawl, causing delays, frustrating users, and overworking your IT team. But don't worry! With Paessler PRTG, you can take control of your bandwidth. It helps you manage network traffic, allocate bandwidth wisely, and stop bottlenecks before they become a problem, ensuring everything runs efficiently.
Diagnose network issues by continuously tracking the amount of bandwidth that flows through your network devices. Advanced bandwidth controlling requires visibility into all network traffic patterns and usage trends. Show bandwidth consumption by IP address, protocol, or port, and other key metrics in real time. Visualize monitoring data in clear graphs and dashboards to identify problems more easily. Gain the overview you need to troubleshoot network performance issues.

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 SNMP Traffic v2 sensor monitors bandwidth and traffic on a device. It can show the following:
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 NetFlow v9 sensor receives traffic data from a NetFlow v9-compatible device and shows the traffic by type. This sensor has several filter options to divide traffic into different channels. It can show the following and more:
The Windows Network Card sensor monitors the bandwidth usage and traffic of a network interface via Windows Management Instrumentation (WMI) or Windows performance counters. 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 helps manage network bandwidth by monitoring usage in real time and providing detailed insights into which applications, devices, or IP addresses are consuming the most bandwidth. It allows you to set limits, throttle traffic, and prioritize critical applications to ensure optimal network performance. With PRTG, you can visualize bandwidth usage patterns, identify potential issues, and make informed decisions to optimize your network.
Yes, PRTG fully supports quality of service (QoS) policies. It allows you to implement these policies to prioritize traffic for critical applications like VoIP or video conferencing. By doing so, you ensure that essential services always have the bandwidth they need to function smoothly, even during peak usage times. This prioritization is key to maintaining high-quality performance for your most important applications.
Absolutely! PRTG is designed to handle all types of network connections, including WAN, VPN, and Wi-Fi. It provides detailed monitoring of traffic across these connections, helping you maintain control over bandwidth utilization in even the most complex network environments. Whether you're supporting remote workers via VPN or managing data flow across multiple sites with WAN, PRTG has you covered.
Yes, PRTG's customizable alert system notifies you immediately when bandwidth usage exceeds predefined thresholds. This proactive approach allows you to take corrective action before bandwidth issues lead to network slowdowns or outages. You can set up alerts to be delivered via email, SMS, or push notifications, ensuring you're always in the loop, no matter where you are.
Yes, PRTG can monitor bandwidth at the device level, allowing you to track usage for individual IP addresses, endpoints, and network devices. This enables more precise control over network traffic and resource allocation. By understanding the bandwidth consumption of specific devices, you can identify and address issues like unauthorized usage or inefficient applications.
Unlike basic tools that only limit traffic, bandwidth control capabilities from PRTG provide deep visibility into network usage patterns before implementing restrictions. This intelligence-driven approach to bandwidth controlling helps identify the root causes of congestion rather than simply capping speeds. PRTG combines real-time monitoring with historical analysis to enable smarter bandwidth control decisions. The solution also integrates with other network management functions, creating a comprehensive approach to network optimization.
Yes, PRTG excels at helping you control your bandwidth across distributed networks. The centralized monitoring platform provides visibility into traffic patterns at all locations, allowing for consistent bandwidth control policies enterprise-wide. Remote probes collect data from each site while maintaining a unified view of network performance. This comprehensive approach to bandwidth control ensures consistent application performance regardless of user location, making it ideal for organizations with branch offices or remote workers.
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.
