PRTG Network Monitor - IT Monitoring vendors

Here's what monitoring looks like in PRTG

We simplify your daily work!

 Network autodiscovery

Network autodiscovery

PRTG can scan network segments by pinging defined IP ranges. This way PRTG will automatically recognize a wide range of devices and systems and create sensors from predefined device templates. This saves you a lot of configuration work and you can start monitoring right away.



With PRTG Maps you can create web pages with up-to-date monitoring data in your desired design. You can even make maps with your monitoring data publicly available. Have an eye on your network like you need it!



PRTG alerts you when it discovers warnings or unusual metrics. With our free Apps for Android, iOS, and Windows Phone you can get push notifications directly to your phone. You can easily setup notifications via email or SMS according to your needs. With our powerful API you can even write your own notification scripts.

Administrators rely on PRTG Network Monitor to monitor their LANs, WANs, servers, websites, appliances, URLs, and more

Network problems create business emergencies. When the network goes down, employees can't read emails. Customers can't purchase the product. Work stops. Network monitoring helps you keep your business healthy:

  • Avoid expensive outages 
  • Address bottlenecks before they cause problems
  • Reduce costs by buying only the hardware you need

Stop wasting time putting out fires. Start building the future foundations of your business. You'll be less stressed and your colleagues will consider you a hero.

Bandwidth monitoring: Find out who Is using your network, for what

PRTG Network Monitor runs on a Windows machine within your network, collecting various statistics from the machines, software, and devices which you designate. (It can also autodiscover them, helping you map out your network.) It also retains the data so you can see historical performance, helping you react to changes.

PRTG comes with an easy-to-use web interface with point-and-click configuration. You can easily share data from it with non-technical colleagues and customers, including via live graphs and custom reports. This will let you plan for network expansion, see what applications are using most of your connection, and make sure that no one is hogging the entire network just to torrent videos.

PRTG can collect data for almost anything of interest on your LAN. It supports multiple protocols for collecting this data:

Knowing when things break is good. Knowing before they break is even better.

PRTG Network Monitor includes more than 200 sensor types for all common network services, including HTTP, SMTP/POP3 (email), FTP, etc. But what is a sensor? One sensor within PRTG is one aspect that you monitor on a device. For example a specific URL, the traffic of a network connection, a port of a switch or the CPU load on a machine. Please have a look at the list of supported sensor types. Every entry in this list counts as one sensor. Normally, we are calculating with between 5 and 10 sensors per device, but of course that depends on what exactly you want to monitor.

We can alert you to outages before your users even notice them, including via email, SMS, or pager. Even better, after you use PRTG to track request times and uptime for a few months, you can optimize your network so your smartphone never gets a push from PRTG again. PRTG can print reports showing how good a job you are doing. (Tell your boss that your 100% uptime last quarter deserves a raise. We'll even print you the report to do it with.)


Most administrators want to test a tool for free before deciding to make an investment.

The many advantages of PRTG:

1. Free trial version: Take the time to explore PRTG so you can determine if it satisfies your needs and meets your expectations. Once the trial is over, it’s easy to upgrade your already configured version of PRTG, which means you’re much less likely to make an incorrect purchase.

2. One tool, one overview: Administrators often use a variety of monitoring solutions for their network or for the individual components of their infrastructure. But using several different tools every time you want to create an overview costs time and energy. PRTG is an “all-in-one” solution. Our dashboard and app provide a comprehensive overview, whenever you want it.

3. Quick customer support: Got a question? Stuck on a problem and need a hand? PRTG is backed by a dedicated development and support team. We do our utmost to answer every customer inquiry within 24 hours (on business days). Browse all our support topics here.

Configure your PRTG today. The trial version is free of charge. Save time, worry, and money with our monitoring tool designed for your network and entire infrastructure.
