PRTG network scanning tools: What you’ll find on this page
Keep your network running smoothly, and hackers at bay
Can you ever be 100% sure you're using network resources as efficiently as possible, and that there are no potential vulnerabilities bad actors could exploit?
No.
But with PRTG’s network scanning tools, you can have the next best thing: a constant eagle eye on every single metric that might impact your network’s performance, health and security.
And when we say constant, we mean 24 hours a day, seven days a week, 365 days a year (well, or 366, if it’s a leap year).
Packed with advanced features, and designed to be user-friendly and intuitive by default, PRTG’s sophisticated sensors track all your network devices’ critical metrics and alert you if something doesn’t look quite right, saving you time, effort, and giving you the peace of mind that you’ll always know about any issues before they cause disruption and unplanned downtime.
PRTG makes scanning your network easy
Custom alerts and data visualizations make it easy to monitor, identify, and prevent bottlenecks, unplanned downtime, service interruptions, suspicious activity, and other network performance and security issues.
A network administrator’s best friend: Why Paessler PRTG

A complete view of your network’s health and security at a glance. Stop wasting time and effort switching between different monitoring environments and get the visibility you need to maximize performance and plan ahead with confidence.
Proactive protection
Nip potential problems in the bud, and strengthen your organization’s cybersecurity. Once you pick your preferred thresholds, PRTG monitors everything round the clock, and built-in automations alert you if there are issues, so you can step in and fix them straight away.
Effortless customization
Tailor your monitoring environment to your exact needs. Create your own library of toplists and topology maps, bespoke charts, graphs, and dashboards, and reporting templates, and configure user-defined thresholds. You can even create custom monitoring sensors.
As user-friendly as it gets
Enter your chosen IP range, and Auto Discovery detects your network devices, assigns the right sensors, and starts monitoring. Job done. You don’t even have to customize or configure (unless you want to). One of PRTG’s key features is that it works right out of the box.
