Why scanning for
network devices is a must

Are you familiar with all the devices in your company’s network? This is highly unlikely, for even small networks are connected to scores of end devices. The bigger and more dynamic your IT environment, the harder it is to keep an eye on all your devices.

A network device scanner automatically searches for and lists network devices. This allows you to keep track of the type and amount of all the devices in your network.



PRTG detects and monitors network devices automatically


Automatic inventory

The PRTG Auto Discovery feature scans a specific IP address range and automatically adds the devices it finds to your monitoring. After the scan, you can tweak the list, group devices together, or create easy-to-read network maps.

Detecting new devices

Detecting new devices

Your network is constantly changing? PRTG scans for new devices in intervals set by the user. You can therefore keep a constant eye on the evolution of your network.

User friendly dashboards

User-friendly dashboards

PRTG comes with customizable dashboards that display your network devices in neatly arranged lists. And thanks to the PRTG app, you can even access these dashboards from your smartphone or tablet while on the go.


Notifications in the event of disruptions and errors

If an error or disruption occurs in the network, you’ll immediately be alerted by SMS, email, or push notification. The threshold values that trigger these notifications can be set manually.

When it makes sense to scan for network devices: 3 examples

Network inventories

A network inventory is a common job for a system administrator. Regular network scans not only provide a much-needed overview, but also contribute to a secure network. During an inventory, you’ll quickly discover if your network contains unwanted devices such as private computers or smartphones.

Efficient Network Planning

More employees, additional tasks or new business areas: all of this usually also requires the network to grow. If you know about your network devices, you can expand your IT infrastructure in a targeted and efficient manner and save costs. 

Network expenses

The accounting department should also keep an eye on the network. The administrator needs an overview of all active hardware and software to ensure the costs for devices, maintenance, and licenses are correct. Regular network scans with PRTG make these checks easy.
