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.

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

"Icinga does the job and is fairly stable."

"The value of Icinga is that it has hundreds of plugins, so it's really easy to monitor pretty much anything."

"The drafts are easy but what I like about Icinga is that there are many add-ons that you can download."

"I like the ability to amend and adjust things really easily, which is useful in a case where you could make it auto-discover and then set a template to say all of these applications or servers under this template have an automatic threshold set that you’d set up manually."

"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."

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

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

"The best thing about the solution is how it highlights errors, the issues, and what needs my attention. The solution directs me to areas that I should look for first."

More Icinga pros

"The most valuable feature of PRTG Network Monitor is the dashboards. We can check to see the resources and the uptime."

"I really love the activity library. It gives the flexibility to discover data and metrics about my interface and data server."

"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."

"It has provided us with early warning for potential issues and has stopped potential downtime before it occurs."

"PRTG gives us true visibility of the downtime of particular circuit functions, so if a circuit is up but not routing traffic, I will know with this tool and can write a customized script for a sensor to detect specific things."

"PRTG is integrated on Windows."

"We are using the basic PRTG that we can download for free, and PRTG is much cheaper than SolarWinds."

"It is easy to use and intuitive, which is really important. It does what it says on the box by giving you a visual of the state of what is going on at any one time."

More PRTG Network Monitor pros

Cons

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

"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."

"Network Discovery capabilities would be extremely helpful."

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

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

"The user interface should be improved."

"It is not really adequate for our current needs. It causes additional issues which we have to work around and takes us time that a better solution would not."

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

More Icinga cons

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

"The traffic, the status of the devices can stand improvement."

"PRTG Network Monitor needs to show bandwidth utilization in proper graphs. It isn't easy to learn."

"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"

"I would like to see more updates available in this solution."

"The technical support service should be improved."

"PRTG could use reporting tools and mobile alert tools. It should be easier to diagnose and respond to problems from a mobile device on the go."

"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."

More PRTG Network Monitor cons

Pricing and Cost Advice

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

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

"The solution is free to use."

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

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

"The solution is cheap."

"It's an open-source solution."

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

"We have an unlimited license for this solution."

"The scalability is there, but smaller companies might need CAM software to be able afford the product."

"PRTG Network Monitor is very expensive."

"We are using the basic PRTG that we can download for free. For now, we only need to monitor less than 100 devices. For more than 100 devices, we would need to buy a license. PRTG is much cheaper than SolarWinds."

"We are licensed for 2500 endpoints."

"The pricing is okay and it is cheaper than some competing products."

"All monitoring system is close to the same pricing scheme."

"Pricing for PRTG Network Monitor is a nine out of ten. It meets my company's budget and monitoring requirements. My company is on a perpetual license."
