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.

Alerting precision has reduced incident response times and improved department-level network visibility

The auto-pause sensor during the maintenance window is good without any false alerts, and it prevents me from getting flooded with alerts during planned maintenance, helping department heads understand their own network usage better. It has reduced incident response time by giving clearer ownership of each alert, ensuring alerts go to the proper recipient. SNMP testers and auto-pause are among the best features of PRTG Network Monitor, which is particularly useful for different departments such as HR and finance, where alerts can be filtered accordingly. The alerting features and dashboard of PRTG Network Monitor are very helpful, especially in our industry. However, the dashboard can look cluttered on smaller screens, which is one negative aspect. PRTG Network Monitor has impacted us positively; we have stopped getting flooded with alerts during planned maintenance or unplanned outages. Compared to others, this gives specific alerts very quickly and helps department heads understand their own network usage better, thus reducing incident response time so that each alert has clear ownership.

Quotes from Members

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

Pros

"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."

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

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

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

"This solution has a self-healing handler where if the service is down, it is automatically restarted."

"We have found the solution to be stable."

"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 features of PRTG Network Monitor are user-friendly, and the graphical interface is good for all the network devices that are mapped in this organization. It's very easy to find reports for any devices that we are looking for."

"We did some research, found PRTG, and I spoke to another company that used it, they really loved it so we went ahead got the free license initially, did a trial, found it absolutely amazing, and then bought it."

"The most valuable feature is the notifications, as long as you spend time and think about what and when you want to be notified, it's always accurate, it is always there, and I find things out before my Internet provider."

"PRTG Network Monitor helps us quickly and easily discover a large number of sensors, so we can spend minimal time monitoring customer sites."

"You should absolutely look at this solution; it gives us everything that we need: the lightweight aspect of it on the network and the amount of information, and it's absolutely worth the money."

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

"With PRTG, we normally know of issues with our servers before anybody reports them."

"We have been extremely satisfied with PRTG's capabilities overall."

More PRTG Network Monitor pros

Cons

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

"At this time, the layout of the website is a bit difficult. It should be more user-friendly for changing the background and logos."

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

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

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

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

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

More Icinga cons

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

"I would like to see Office 365 monitoring. Essentially, it doesn't do it."

"The operations dashboard is only available in PRTG's enterprise version, but I wish it could be accessed in the standard licensing. It would also be nice if PRTG had templates for dashboard monitoring, software monitoring, etc. It can help me set up a dashboard because now we don't have a template from PRTG, so we need to create one from scratch."

"I am not sure the solution is giving me all the needed feedback that we need. When something goes off on our IT infrastructure, it does tell me. However, it would be nice if it gave more intuitive information, e.g., the hard drive has gone up by 60 percent in an hour."

"It would be good if there were better graphical interfaces when you have it on multiple monitors... Because we have so many servers, things can get lost in the fog a little bit. Maybe having a better way of showing different geographies, Flash, etc., would help."

"If they are looking for complex reports, I will say stay away from this product."

"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."

"It's expensive to maintain."

More PRTG Network Monitor cons

Pricing and Cost Advice

"The solution is cheap."

"The solution is free to use."

"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."

"It's an open-source solution."

"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."

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

"We pay nothing for it. Its 100 sensors have allowed us to put a magnifying glass on some systems, providing an extra layer of detail. Therefore, our outgoing is nothing and our incoming is a lot of useful data that we can react to proactively."

"We have an unlimited license for this solution."

"PRTG Network Monitor is not that expensive, so I like it cost-wise. There's no additional cost apart from the standard licensing fees. On a scale of one to five, with one being the cheapest and five being the most expensive, I would rate the cost of PRTG Network Monitor a two."

"We are licensed for 2500 endpoints."

"The price is actually on the cheaper side. If you're going with the unlimited license code, it's very cheap compared to competitors unless you're going for something free, like Zabbix. But you get what you pay for, and it doesn't have the full suite of products or tools like SolarWinds or a ScienceLogic."

"Right now, the smallest sensor pack that they have is just a bit out of range for me, as a business. This kills me, as I need the product. Therefore, there is always a balance between needing to buy it or continuing their free version."

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

"We used a product called SolarWinds in the past, and its cost was high. Whereas, PRTG came in at a third of SolarWind's cost."
