Executive SummaryUpdated on Mar 29, 2026

PRTG Network Monitor and Icinga are two leading products competing in the network monitoring software category. While PRTG is favored for its user-friendly setup and comprehensive alert system, Icinga stands out with customization and integration options, appealing to users with technical expertise.

Features: PRTG Network Monitor is known for extensive notification features, allowing alerts before issues occur, supported by sensors and a solid server/client infrastructure. It includes numerous plugins and offers a simple setup. Icinga focuses on automation and integration through its APIs and open-source nature, which permits extensive customization. It effectively integrates with third-party solutions and monitors varied environments.

Room for Improvement: PRTG Network Monitor could enhance its desktop application for better intuitiveness, improve database structure, and reporting features. Users suggest scalable solutions for enterprise needs and better technical support. Icinga could streamline its user interface and simplify its setup process, along with improving dashboard features and platform integration capabilities.

Ease of Deployment and Customer Service: PRTG supports on-premises, hybrid, and cloud configurations, offering deployment versatility. Customer service has mixed feedback, with some noting swift responses while others mention delays. Icinga, primarily on-premises with strong community support, may lack immediate support but compensates with responsiveness in forums. PRTG offers greater cloud compatibility, whereas Icinga requires more initial technical expertise.

Pricing and ROI: PRTG Network Monitor provides flexible licensing suitable for various business sizes but can be expensive as it scales. It offers significant ROI by minimizing downtime with its monitoring features. Icinga’s open-source model makes it cost-effective for technically skilled users, with commercial support available for a fee. While Icinga lowers initial costs, PRTG provides a more comprehensive solution at a higher expense, with both offering valuable returns depending on user needs.

Easy to use, and it's possible to customize the product as per the needs we may have but average multi-tenancy aspect

It's supported by the community. We use Icinga, which is not part of the Open-Source platform but is wrapped into a commercial solution from another provider, a local provider in Italy. Icinga is an open-source platform, so it is supported by the community. It's quite easy to use, and it's possible to customize the product as per the needs we may have. So it's not expensive, and it's quite a general purpose. We can easily monitor any kind of infrastructure we encounter. The ability to customize scripts and build your own queries to request information from the infrastructure elements you want to monitor. This level of personalization and customization is highly appreciated. The alerting is the same as any other monitoring platform. It's not a "wow" feature that has changed our lives, but it's perfectly adequate.

Senior consultant at Cambridge Institute of Technology

Has reduced troubleshooting time and improved issue detection through sensor alerts and team collaboration

PRTG Network Monitor can be improved because the dashboard themes feel outdated. It should be updated to a newer version for the new Gen Z customers. The notification sound options are limited unless customized. Restarting probes after Windows updates is necessary, and there should be some kind of automatic restart. The initial auto-discovery added too many unnecessary sensors, so auto-discovery should only take the necessary sensors into consideration.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The most valuable feature is one that not many are even aware of, as Icinga has a self-healing event handler where if the service is down, it is automatically restarted, and you can configure the handler to take action after the critical alarm without human interaction."

"An affordable solution for small organizations to do basic network monitoring."

"Icinga does the job and is fairly stable."

"It is really easy in Icinga to create your own plugin and integrate it without any fuss. And it works just perfectly fine."

"People should know that it is simple and advanced."

"We have found the solution to be stable."

"I use it for monitoring infrastructure and it was very good for that issue."

"There's a module called Icinga Director, which helps us configure the product using an intuitive interface through clicks instead of creating a text configuration. It's very helpful for us."

More Icinga pros

"It is a very stable solution. There are no bugs, glitches and we have not experienced any crashing."

"The solution provides us response times to issues."

"One of its valuable features is the fact that it handles multiple operating systems... And I like the fact that it tells me when things are about to fall over, which means I can preempt it and not have to wake up at three in the morning to fix it."

"Its initial setup process is fast and easy."

"The most valuable features of PRTG Network Monitor are the threshold notification when certain traffic increases and goes beyond the defined threshold. The up and down status email notifications and other notifications are useful. Additionally, it is user-friendly, and customizable, and there are many features available."

"As far as network monitoring and analysis, I cannot think of a more intuitive and flexible product on the market today."

"It helps the entire organization become digitally enabled."

"It's great that we can create a dashboard inside software monitoring, and access many other websites, it is a complete monitoring solution."

More PRTG Network Monitor pros

Cons

"There is room for improvement in multi-tenancy. It's not perfect, not even really good. It's average, but it should be improved."

"One thing that Icinga lacks is the capability to create advanced and customized dashboards within the tool itself."

"Scalability is problematic. If you have a stable environment it's good, but if the environment is growing, I had some problems with Icinga."

"The tool currently fails to provide notifications to users."

"It needs Trap SNMP. I saw the documentation for Zabbix, that it has its own built-in product which handles SNMP traps, and there's nothing similar in Icinga or Nagios. I think this feature is most important for me."

"Icinga is a complex solution that's hard to learn. It's a powerful product for monitoring, but new users will have a hard time figuring out what to do."

"I think the software is quite good, but we have had problems with getting it to recognize certain areas and amend certain checks, where we needed so we would have to create backend scripts for those checks. Though, being open source, it has the support to create backend scripts, it would be better to have these scripts in-built."

"Icinga’s automation could be improved."

More Icinga cons

"The scalability of this solution could improve as well as the automated provisioning of the infrastructure."

"I posed this question to PRTG and they were unresponsive, so it seems like not enough customers are complaining about it or would be potentially using it."

"There seems to be a big jump from the basic scan to the really thorough scan."

"I would like a more straightforward ability to create dashboards and maps. The network maps should be a bit more flexibility in the GUI to do what we need to do."

"Sometimes the error messages are too vague and don't directly tell me what went wrong."

"PRTG Network Monitor can be improved as there is a lot of manual cleanup needed, which could be reduced."

"PRTG Network Monitor could improve by having descriptions for the tab usages. The dashboards or interface could be easier to understand."

"The desktop app is terrible."

More PRTG Network Monitor cons

Pricing and Cost Advice

"It is cost-effective, and the return on investment can be very interesting because the price is low."

"The solution is free to use."

"The product is inexpensive compared to other DBM products."

"Even though Icinga's financial cost is low, it is an expensive product regarding the resources required to maintain and operate it."

"It's an open-source solution."

"The solution is cheap."

"This is an open-source solution with paid support."

"We're using the free version of Icinga."

"The price is pretty comparable."

"The pricing for PRTG in our case is reasonable because we have a lot of applications to monitor within PRTG. It is not that expensive."

"We are using the premium version of PRTG Network Monitor. The price of the solution is a bit higher than competitors but it is worth the extra money. However, it would be helpful if the price was lower."

"Because we are only on the free version, we have a limited number of sensors. Therefore, we are not monitoring as much as we want to be to obtain historical information."

"There is a license to use PRTG Network Monitor and it is annually."

"Licenses are very expensive, so I would like to see cheaper licensing."

"PRTG Network Monitor is cheap."

"We have an unlimited license for this solution."
