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

"Icinga has multiple automation and integration features. There is an API for everything and a web UI for configurations. The APIs enable you to automate tasks in Icinga. We can also use plugins to talk to the API. The Icinga Director talks to a database in the background, and you can import settings from the CMDB to all systems in Icinga."

"Icinga2 was designed to delegate, distribute and balance tasks between several nodes."

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

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

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

"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."

"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."

"We monitor all, starting from UPS to international mail chains."

More Icinga pros

"The authentication links into our standard Active Directory authentication, which is very good."

"The most valuable feature is the ability to span multiple technologies and multiple vendors."

"The best feature is that it lets me know what is going on. I need to know if something has gone down, I need to know if something is running very slowly. PRTG tells me that."

"PRTG Network Monitor is easy to set up. Within a few minutes, it is operational."

"If someone were looking for a basic monitoring tool for servers and networks, I would recommend PRTG Network Monitor."

"PRTG Network Monitor's best features are its flexibility, ease of implementation, user-friendliness, and intuitive interfaces."

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

"Time is the biggest thing that I have, and it's given me that back a bit."

More PRTG Network Monitor pros

Cons

"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."

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

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

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

"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 connection between Icinga and Icinga Web."

"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."

More Icinga cons

"They should work on syncing the solution with Gmail."

"The setup aspect of it and getting devices working needs improvement."

"PRTG Network Monitor can improve the reports."

"The technical support needs some improvement. The response time is slow, we normally get a response the next business day for urgent issues which is long time."

"The remote probes are okay. I think that there could be more sensors available, especially with newer technologies coming along."

"The desktop app is terrible."

"The automation should be improved."

"I wouldn't mind better categories for the sensors."

More PRTG Network Monitor cons

Pricing and Cost Advice

"The solution is free to use."

"The solution is cheap."

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

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

"It's an open-source solution."

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

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

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

"At the moment I'm only using 500 sensors. I pay yearly, so it's a cost that's easily swallowed."

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

"Sensors on free version can run out quick."

"If you are not too sure about it, try the free version. Then, if you like it, you can go to the paid version and roll it out."

"The price was pretty good, very competitive."

"I rate the licensing for PRTG Network Monitor an eight out of ten."

"On a yearly basis, I believe it's between £1,200 and £1,500."

"PRTG Network Monitor is very expensive."
