How well do you really know PRTG? 3 major advantages at a glance

One tool for your entire network

Devices, applications, bandwidth: PRTG keeps an eye on everything. And that’s important, because just one malfunctioning switch can cause disruptions – and require hours of troubleshooting. A clear advantage of PRTG over “smaller” alternatives. 

All-in-one monitoring

Notification system, reports, and of course, all sensors: with PRTG, all monitoring features are included. You can even monitor Cisco devices with our tool. With other monitoring software, you usually have to pay for such features.

Flexible licensing model

Want to start small? Good idea! Thanks to our flexible licensing model, you can upgrade whenever you please. Each PRTG license comes with a certain number of sensors. You pay for exactly what you need to monitor your network.

Why this company chose PRTG instead of ManageEngine and SolarWinds:

We used OpManager for a couple of years, and also evaluated Solarwinds and Nimsoft, but I wanted to see if there was anything better on the market. In terms of price-performance ratio, it does everything we need it to.”

Alex Malinov, Head of IT, Fulham FC.
