Is a free software really cheaper?

Free monitoring


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 time savings with an easy-to-use software are enormous over a longer period of time. 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 on the installation file and follow the dialog – that is how easy it is to install PRTG. Within a few minutes, PRTG is ready to use 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 assistant, adding 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

Agentless Monitoring


In PRTG, you do not need to install any software on the devices to be monitored – the monitoring tool is “agentless”. PRTG uses known protocols such as SNMP, WMI, NetFlow or SSH for monitoring. This way, not only is the burden lower, the monitoring is done quickly and easily.

Zabbix, in contrast, can only monitor devices once an agent is installed on them. Especially in a heterogeneous network, setting up monitoring often requires a substantial time investment.

Time, which you as admin could save and use for more important tasks.

PRTG is intuitive and easy to use 

PRTG ist intuitiv


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

Technical support is included in the price of PRTG

Free monitoring


The price of a PRTG license includes free maintenance for one year, multi-year maintenance (24 or 36 months) is subject to a fee. In case of a problem, you will receive competent help from our support team within one business day. So, a tedious search and testing of solutions from forums is not necessary. As an open source program, Zabbix is free, but you would have to purchase paid packages for support from the manufacturer.

Those who compare, know better

“Zabbix is free, which is decisive for some people. But infrastructure monitoring is so immensely important for a company that the price of a perpetual PRTG license is almost too low.”
