Is a free software really cheaper?


Why should you use paid software if there is a free open-source version available? At first glance, Zabbix seems much more attractive than PRTG Network Monitor financially.

However, especially in the case of frequently used software that is important for smooth business operations, the purchasing price is only one part of the costs. The amount of time you save with an easy-to-use software is enormous over a longer period. Usability and intuitive operation or setup are one of the biggest pluses of PRTG, which are also always highlighted by our customers.

With PRTG, you save time and money and have a software that is fun!









Installation and setup: Save time and nerves with PRTG



To install PRTG, you only need a Windows computer with sufficient computing power (you can read about the precise requirements here). Requirements for installing Zabbix are Apache, PHP, and a MySQL database.

Installation process

Installation process

Double-click the installation file and follow the steps in the installation wizard – this is how easy it is to install PRTG. Within a few minutes, PRTG is ready to be used and you can start setting it up. In Zabbix, you have to set up Apache and a MySQL database and then correctly configure PHP. Although there are instructions for each step, additional time is required.



After installation, you have the option in PRTG to automatically search for available network devices and services and create sensors. Thanks to a clear graphic user interface, the process of adding, editing, and deleting sensors is very intuitive. In Zabbix, on the other hand, automatic network discovery is anything but easy and is possible only in a very technical way using countless SNMP commands.

Adding sensors in PRTG later on also just takes a few clicks. You either add the new sensors manually or run a new discovery process on a specific device. Thanks to the easy-to-use dialog, this is particularly simple. Zabbix asks for a new manual definition of many parameters such as the SNMP version or authentication method for each sensor.


Agentless monitoring: Easy setup, lean operation

In PRTG, you do not need to install any software on the devices that you want to monitor – the monitoring tool is “agentless”. PRTG uses known protocols such as SNMP, WMI, NetFlow or SSH to integrate devices and services from any vendor or provider.

Zabbix on the other hand offers only a limited range of functions such as TCP port check, ping or SSH without the installation of agents. To monitor CPU usage, memory or system uptime, agents must be installed on the target systems. Especially in a heterogeneous network, setting up monitoring often requires a substantial time investment.

Time that you as an admin could save and use for more important tasks.


PRTG is intuitive and easy to use 

A monitoring solution should be as easy as possible in operation. For this reason, we work a lot on developing and constantly improving our user interface. In independent tests, PRTG Network Monitor usually has the first place due to its user-friendliness and easy operation.

Technical support is included in the price of PRTG
