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

"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."

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

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

"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."

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

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

"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."

"Icinga does the job and is fairly stable."

More Icinga pros

"What I've found most valuable is the custom sensor, which allows you to write scripts or code to monitor a specific metric in your environment."

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

"Stable and scalable network monitoring tool. Installation is simple and straightforward."

"The solution is scalable."

"My opinion is that this solution is not very expensive."

"The sensors and remote probes are phenomenal. We use them for all of our global sites. The problem with our global sites are that they are all VPNs. If the link goes down, you can't monitor other solutions, as it just goes off the grid. Having remote probes allows them to still carry on and get the information that we need when it comes back up, sending the information to us."

"The remote probe feature in PRTG Network Monitor helps you monitor remote systems or your network at a lower cost than other solutions."

"The scalability is good. You can improve a remote host or the clustering. This gives it the flexibility to monitor another infrastructure remotely."

More PRTG Network Monitor pros

Cons

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

"The connection between Icinga and Icinga Web."

"The installation and configuration are very complex."

"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."

"Icinga’s automation could be improved."

"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."

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

More Icinga cons

"If PRTG could help me see the bandwidth for each host I have on my network, either for a wireless or a wired network, that would be very helpful."

"We have had a few issues with the web elements, as far as the dashboard. With the dashboard, it has to be manually refreshed. Occasionally, we reboot the server, or at least web services, due to the web aspect."

"In terms of sensors and probes, it would be really cool if PRTG had a purely Azure-based solution. We had to install a probe on one of our cloud servers and then let that probe out from there. It would be really cool if it just monitored Azure without having to install something on the device."

"PRTG Network Monitor could improve interaction with customers by offering direct support involvement instead of just mail responses."

"PRTG's application monitoring sensor is not strong."

"The thing that we do struggle with a bit is in the historic data. If I want look over 30 days, because it averages out onto one graph, you can't zoom in and drill down information."

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

"They need to address the slowness issue that sometimes occurs with PRTG Network Monitor."

More PRTG Network Monitor cons

Pricing and Cost Advice

"It's an open-source solution."

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

"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."

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

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

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

"It is expensive."

"PRTG Network Monitor is cheap."

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

"I rate the price of PRTG Network Monitor an eight on a scale of one to ten, where one is a high price, and ten is a low price."

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

"The price of PRTG is reasonable. PRTG's competitors like SolarWinds and ManageEngine charge more for the same functionality."

"We pay for PRTG Network Monitor annually. The price is approximately 10,000 rupees annually."

"The pricing is not too bad. It's not massively expensive, and the ability to upscale or even downscale licenses every year is brilliant for us."
