PRTG network device scanner: What you’ll find on this page
PRTG makes tracking network usage easy
Custom alerts and data visualizations make it easy to monitor, identify, and prevent low bandwidth, packet loss, latency, and other network performance issues.
Power up your all-seeing network eye PRTG and scan your network’s devices
For sysadmins and IT leaders, one of the truths you must embrace is that you don’t know all your devices. Even small networks are connected to scores of end devices; the bigger and more dynamic your IT infrastructure, the harder it is to watch everything. Paessler PRTG cuts through the noise and gives you instant, automatic visibility to your entire network.
Make device inventory management a breeze
New devices come online, old devices go offline, and connections can be reconfigured on a daily, weekly, or monthly basis. Keeping track of the ins and outs can be a full-time task.
PRTG’s automatic network discovery takes the complexity out of inventory management, automatically adding new devices to your monitoring.
Set scanning intervals & have it your way
Depending on the complexity and size of your network, you may need to scan it monthly or even weekly to identify changes.
Our network device scanner PRTG allows you to set the intervals between scans to keep a constant eye on your network’s evolution. After the scan, you can tweak the list, group devices, or create easy-to-read network maps.
Detect vulnerabilities & unauthorized access
Network security is always a concern, no matter the size of an organization. PRTG is a team player in your security.
It detects outdated software vulnerabilities and unwanted devices with unauthorized access, such as private computers or cell phones. This is particularly important in environments where sensitive data is handled.
Keep your network healthy & devices running
Monitoring the health and status of your devices is a crucial part of network device management. PRTG makes proactive management easy with real-time monitoring and alerts.
The network device scanning software continuously gathers operational data from each device on the network, including memory and CPU usage, network traffic volume, and more.
Quickly identify failures and redundancies
Effective network management means ensuring your network is resilient, efficient, and capable of meeting user demands. PRTG helps you identify over- or underutilized resources, at-risk components, or failed devices.
With this information, sysadmins can better guide their teams in resource allocation, load balancing, root cause analysis, and preventative maintenance.
Take strategic network planning to the next level
Knowing what’s going on in your network at any given point makes strategic planning that much easier. PRTG gives you that information to make informed decisions about where to add capacity or scale back.
Know where to invest for strategic upgrades, expansions, or enhancements with real-time and historical data.

Network device scanner: FAQ
What is network device scanning?
Network device scanning automatically identifies all the devices connected to a network. This includes their attributes, such as IP addresses, device types, operating systems, versions, and configurations.
Why should I use a network device scanner?
Scanning is important for keeping an up-to-date view of the network’s infrastructure. Among other tasks, network device scanning helps IT teams:
- Build automatic network inventories
- Efficiently plan network upgraded
- Increase security by detecting unauthorized devices
- Optimize network performance
- Lower network expenses
How often should I conduct network scans?
How often depends very much on your organization’s size, the complexity of the network, and your industry’s regulations. Typically, at least once a day is recommended.
What makes PRTG different from other network scanning tools?
PRTG as a network device scanner stands out for many reasons. Here are the top three:
- PRTG is well-known for its user-friendly interface
- Because of its sensor-based approach, it’s a leading provider of comprehensive network monitoring
- PRTG is highly customizable
- PRTG can scale with your organization’s network
- PRTG not only scans your LAN, but also your virtual devices, as well as your cloud environment
What is a sensor in PRTG?
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.
