PRTG vs Zabbix Comparison for Network Monitoring and Management


Marc Wilson UPDATED: March 31, 2023

When looking for the differences between PRTG vs Zabbix, in terms of Network, Server and Infrastructure monitoring, we want to evenly consider the benefits, pros & cons and strengths/weaknesses of each software suite before making the decision on which one to deploy in our environments. We'll layout out which is the best choice for networking monitoring and a table laying out their features and options.

Some major considerations that we've brought up in previous comparisons and breakdowns of PRTG and other major open-source and commercial alternatives are as follows:

  • Support and Enterprise Assistance (Most Important for us)
  • Ease of Configuration and Intuitiveness
  • Scalability for Future Growth
  • Automatic Network Discovery and Mapping
  • Extensive Hardware Vendor Support (OID's and MIB)
  • Alerts, Reporting, and Notifications (via Email/SMS)
  • UI Friendliness and Ease of Use
  • Web/Mobile Accessibility and/or App

These requirements above are just a few things we are looking for when comparing these two software suites, and furthermore, how well they perform in real-world environments.


One of the most important, if not THE MOST important, questions is Pricing.

Zabbix is a Free, Open-Source software package. However, we do not recommend you make your decision based on price alone. As many admins and engineers realize at one point or another in their IT career, you will eventually need help with an issue that arises from a software package you are using.

This is where Support and/or Google comes into play. When dealing with an open-source, Free software package, you'll notice that support is at times, lackluster.

PRTG, on the other hand, has a Free version that allows you to monitor up to 100 Sensors for as long as you want. You can also download and use the unlimited version on a 30-day free trial to discover your requirements.

  • Uses a combination of packet sniffing, WMI, and SNMP to report network performance data
  • Fully customizable dashboard is great for both lone administrators as well as NOC teams
  • Drag and drop editor makes it easy to build custom views and reports
  • Supports a wide range of alert mediums such as SMS, email, and third-party integrations into platforms like Slack
  • Each sensor is specifically designed to monitor each application, for example, there are prebuilt sensors whose specific purpose is to capture and monitor VoIP activity
  • Supports a freeware version


  • Is a very comprehensive platform with many features and moving parts that require time to learn

Don't let PRTG's price fool you though, as with Zabbix, if you are looking to Buy Enterprise Support or even Migration/Update services, the pricing is not made public, only the levels of support are, as seen below:


  • Open-source transparent tool
  • Uses both SNMP and ICMP for a broader monitoring range
  • Can detect new devices and configuration changes immediately
  • Offers useful templates for quick insights
  • Robust notification system supports SMS, email, custom script, and webhook


  • The interface isn’t as intuitive as solutions such as DataDog or Site24x7
  • Would like to see better-alerting features, specifically related to reducing false positives

Zabbix Upgrade services are however made public, and can be seen here: http://www.zabbix.com/upgrade_services
