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

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

"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."

"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."

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

"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."

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

"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."

More Icinga pros

"We have seen an ROI as it allows us to avoid downtime."

"The most valuable feature of this solution is being able to see things graphically."

"PRTG Network Monitor has positively impacted my organization as the hourly basis has been reduced, making a significant impact."

"The solution has enabled our IT department to be more cost-effective; it cuts down on downtime, brings to our attention the operational problems that we have so we can focus our attention on those, and constantly ensures our systems are up and running in a solid position, effectively removing the costs attributed to downtime."

"My advice to others is if you can't afford SolarWinds and those other expensive solutions, PRTG Network Monitor is the best value for money."

"The email notifications are helpful, and the dashboards are user-friendly for people with little network monitoring knowledge."

"PRTG is relatively intuitive and fairly straightforward. It has net flow monitoring and that works all right. I would describe it as a decent middle-of-the-road solution."

"Its initial setup process is fast and easy."

More PRTG Network Monitor pros

Cons

"Icinga’s automation could be improved."

"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."

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

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

"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."

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

"Network Discovery capabilities would be extremely helpful."

More Icinga cons

"For smaller networks, I would recommend this solution. That said, if the network is complex, I would recommend a company evaluates another product instead."

"Users need to buy the more expensive licenses if they expect to be able to scale."

"This product can be improved by updating the net flow interface. The one that is in place works – I can get all the information I need from it – but it is a little bit clunky."

"I'd like to see the inventory of the device improved."

"The technical support services could be better."

"I would like the ability to monitor Cisco IRS devices."

"The remote probes seem to be a little bit buggy at times. They just stop working or they say they can't communicate. What we tend to do to is install the remote app onto the servers that we use. That seems to clear it up."

"PRTG does not allow us to scan devices like we can scan software or another problem in it. Also, I cannot draw graphical graphs in Woodview/look. Another problem is that we cannot draw a good diagram in PRTG."

More PRTG Network Monitor cons

Pricing and Cost Advice

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

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

"The solution is free to use."

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

"The solution is cheap."

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

"It's an open-source solution."

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

"We looked at PRTG and SolarWinds. From a cost side perspective, compared to PRTG, and from what you get back from it, PRTG was sort of a hands down the winner."

"If you're looking for a cost effective software I’d suggest this product."

"We bought a license for 4000 sensors."

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

"The price of PRTG Network Monitor is reasonable for the features that the solution provides. They charge you per monitoring, not per node, it is per port that you need for a device."

"It is about £4,500 for the first year, then about another 15 to 20 percent annually after that. So, we are looking at about £1000 running costs a year. When you think about how much an outage costs per minute, it's negligible."

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

"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."
