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 apply rules feature saves a lot of time."

"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."

"Macros and the ability to connect it to Google Maps are valuable features."

"If you have a small infrastructure or a small number of devices that you want to monitor, then I think it's a good solution."

"Icinga does the job and is fairly stable."

"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."

"I would recommend Icinga; it's an open-source solution, it's quite easy and simple to use, and checks can be run with Python code and Shell Script code."

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

More Icinga pros

"My company runs a large scale SAAS infrastructure with a large mix of technologies, and PRTG is the first software product we have used to accurately alert the right people of trouble."

"The initial setup was surprisingly easy, the way the menus are all laid out."

"The support is fantastic."

"It will take care of all your monitoring needs, pretty much, but just be conscious of scale."

"You will not find anything cheaper that really does the job."

"The feature set is very strong compared to other products that I have used; it's great because it does everything that we need it to do, it's easy to use, and it looks great when you present it in an open office environment."

"The most valuable feature is the dashboard interface. It's very clean, it's very simple to use."

"The reporting module is easy to configure."

More PRTG Network Monitor pros

Cons

"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."

"The solution lacks many features important to higher-level IT management and network support."

"We have found some problems with Nagios, and support isn't very responsive."

"Network Discovery capabilities would be extremely helpful."

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

"Sometimes, it is very hard to keep an overview of what's happening."

"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."

"One of the areas that are frustrating is remote monitoring for more than one machine."

More Icinga cons

"They just released a newer version of the desktop app, a beta version, that I have been trialing out. I prefer the older version, only because of how the layout is designed"

"There seems to be a big jump from the basic scan to the really thorough scan. There is a big jump in the quantity of sensors it uses for certain things. One minute you might get ten and then the next you get 200. There seems to be a big jump between the two at times."

"The reporting features look very technical and that can be improved."

"PRTG access works best from the web GUI. There are dedicated apps on Windows/Android/iOS, but they are slow and don’t work as well as the web GUI."

"Dashboards can look cluttered on smaller screens, and the UI can feel crowded when there are hundreds of sensors in one group."

"The dashboarding definitely needs improvement."

"The solution could be better and faster when it comes to performance."

"PRTG Network Monitor needs to enhance network performance monitoring. Moving towards observability, similar to what Datadog offers, could be beneficial."

More PRTG Network Monitor cons

Pricing and Cost Advice

"The solution is cheap."

"It's an open-source solution."

"The solution is free to use."

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

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

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

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

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

"One thing I like is that when you buy sensors, it's a perpetual license, so once you buy 2,000 sensors, you've got 2,000 sensors; it's not a recurring cost."

"PRTG Network Monitor's price is a little high."

"We have an unlimited perpetual license, so we just pay support costs and it can scale throughout the organization."

"When you buy PRTG, everything comes in one bundle. Licensing is very easy."

"The pricing is very low compared to other solutions."

"The pricing is comparable."

"Cost was a factor when selecting this solution, but it just did everything we wanted it to do."

"The pricing is reasonable for the features provided."
