Transform your network management: simplify operations and boost reliability with PRTG's network monitoring service











Reliable network monitoring for maximum efficiency with PRTG

A failed router, bandwidth bottleneck, or inaccessible website or online store can have a severe impact on the operation and processes of your business. Among other things, productivity and communication (with both customers and employees) can suffer.

To avoid such incidents, your company – whether it has a straightforward or complex IT infrastructure – needs continuous network monitoring. With a network monitoring service like PRTG, you can check your network automatically.


What is a network monitoring service?

A network monitoring service lets you keep a close eye on your network and make sure it is always available and running properly. Potential sources of errors and malfunctions are detected proactively. If a problem occurs, admins can quickly find the cause and take action at once.

But that’s not all: as a network management solution, a network monitoring service helps administrators to optimize the use of their resources and their corporate network.








What should I look for in a network monitoring service?

Which features should it include? In particular, a network monitoring service should:

  • Be thorough and also keep a constant eye on details.
  • Run day and night without interruptions.
  • Allow for the definition of customizable threshold values to prevent incidents.
  • Allow for the prompt detection of anomalies.

What makes PRTG special?

PRTG is the perfect network monitoring service tool. Here are some of the reasons why PRTG is unique:



 i How PRTG defines sensors

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.

The PRTG network monitoring service is suitable and scalable for companies of all sizes. It monitors both simple and complex IT infrastructures. Small and large companies alike can benefit from PRTG, thanks to flexible licenses that adapt to the growth of your business. You can even downgrade at any time.

What’s more, PRTG is an all-in-one monitoring solution where every PRTG license or subscription comes with all monitoring features.The price of the license depends on the required number of sensors.

Das Monitoring mit PRTG ist umfassend


PRTG monitoring is comprehensive

PRTG monitors all the essential aspects of your entire IT infrastructure. After all, you can only really rest assured with a tool that keeps an eye on everything:

  • Networks (physical, virtual, hybrid)
  • Network devices (servers, firewalls, switches, routers, etc.)
  • Systems
  • Services
  • Applications

Das Monitoring mit PRTG ist unterbrechungsfrei


PRTG monitoring is continuous

PRTG monitoring runs behind the scenes, 24/7. It automatically monitors all the parameters of your systems or network – including data traffic, bandwidth, availability, performance, speed, and utilization – around the clock.


Monitoring mit PRTG ist benutzerfreundlich

PRTG monitoring is user-friendly

PRTG is ready for use in a few short minutes: the network monitoring service is quick and easy to configure. PRTG is installed in a matter of clicks. In addition, the PRTG Auto Discovery feature automatically scans your network and adds available devices to your monitoring setup. And to save you even more time: PRTG is extremely user-friendly and further simplifies your setup by providing 250+ preconfigured sensors for a wide variety of uses and manufacturers. 

This generic sensor uses the Simple Network Management Protocol (SNMP) to monitor SNMP traffic in your system.

This sensor monitors traffic on devices that are compatible with NetFlow v5. Traffic is broken down by IP address, connection, and protocol.

The WMI Free Disk Space sensor uses Windows Management Instrumentation (WMI) to keep track of the available disk space on one or more drives.

PRTG also comes with a customizable alarm system to keep you informed of unusual incidents and anomalies. Alerts can be sent by email, SMS, or a push notification to a smartphone. PRTG also sends Microsoft Teams and Slack messages, and relays notifications via HTTP.

Monitoring als Service für MSPs

Monitoring as a service for MSPs

IT services are sometimes outsourced to MSPs (managed service providers). If you’re an MSP who monitors the IT infrastructure and networks of your customers, PRTG is the perfect tool for your network monitoring service. PRTG is multi-tenant software, which means your customers can also access their monitoring environment. Thanks to its high level of data security and reliable rights management system, PRTG is extremely popular with managed service providers.

MSPs can use any PRTG product for their services, including PRTG Hosted Monitor. This product runs in the cloud, eliminating the need for hardware and allowing for quick and efficient scaling.
