Executive SummaryUpdated on Oct 12, 2026

NETSCOUT nGeniusONE and Icinga are tools that operate in the IT monitoring and analytics domain. NETSCOUT nGeniusONE appears to have the upper hand due to its comprehensive performance monitoring capabilities and versatile deployment options.

Features: NETSCOUT nGeniusONE provides in-depth packet-level analysis, a comprehensive single pane view, and interoperability across multi-vendor environments, offering enhanced decision-making. Icinga focuses on infrastructure monitoring with support for automation and integration but relies on external tools for advanced features.

Room for Improvement: NETSCOUT nGeniusONE faces challenges related to complexity, high costs, and the need for better usability and integration across features. It also requires more comprehensive training resources and improved connectivity solutions. Icinga needs advanced dashboard capabilities and more detailed support documentation, making it less user-friendly compared to established APM tools.

Ease of Deployment and Customer Service: NETSCOUT nGeniusONE supports on-premises, hybrid, and private cloud environments and offers responsive technical support. However, its complexity might necessitate dedicated resources. Icinga is simpler to set up and supports mainly on-premises environments with good community support, though responses to complex issues may be slower.

Pricing and ROI: NETSCOUT nGeniusONE is known for premium pricing, reflecting its extensive features and support, but delivers significant ROI through reduced troubleshooting times. Icinga, being open-source, provides a cost-effective solution for smaller organizations, yet may lead to indirect costs related to manual setup. The open-source nature of Icinga allows for high ROI due to its low financial barrier, though it relies heavily on user expertise.

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.

Monitoring has improved bandwidth insights and application diagnosis but setup and costs still need work

They need room for improvement about the spare parts. There are shortages in Egypt in their stock. We tried to make RMA for specific parts, and it took a long time. Comparing this to a vendor like Cisco, who provides any component next business day, NETSCOUT nGeniusONE took a long time. This needs more improvement. I believe it is expensive. They need to reduce its budget a little bit. Comparing to other solutions, it is very expensive.

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."

"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."

"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."

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

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

"Icinga does the job and is fairly stable."

"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."

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

More Icinga pros

"This solution has cut our overall troubleshooting time by several days."

"I like the single pane of glass view. I like being able to go to one place instead of having to hunt around for everything."

"The valuable features include packet analysis, packet capture, and [that] it's easy to use."

"My clients have received a return on investments and have expanded."

"Deep packet inspection is a very useful tool as it works in real time and uses serial packet-level analysis."

"It catches bigger issues on a weekly basis. That's how often we find something big enough that the only reason we know about it is because of the nGeniusONE. The bigger issues are mostly security-type issues: Odd traffic leaving our network or coming into it, that has found its way past a firewall."

"From the standpoint of VoLTE and related things, it's providing visibility into the network and how it operates."

"With NETSCOUT, it's very easy to check where the problem is located, and you can uncover if it is in the network or the application or the server."

More NETSCOUT Network & Application Observability pros

Cons

"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."

"The installation and configuration are very complex."

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

"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."

"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."

"In general, the product does not look good. However, it does what it is supposed to do. So, the improvements should focus on usability and UI."

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

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

More Icinga cons

"Room for improvement exists in filtering in the packet decode."

"There is currently less visibility or GUI to analyse the packet for troubleshooting purposes."

"For the most part, it's relatively stable. However, there are some times where it seems like it runs a little slow and you have to reset things to get it back going again."

"We see it overload once in a while. It doesn't have built-in protection. Therefore, once it gets too much data, it tends to crash. Then, we have to recover it."

"Initially, we were having a lot of issues with bugs when using version 6.1.1. There were a lot of problems with the dashboard causing confusion. We worked with our SE and the NETSCOUT engineering team to fix the visibility with the data. There should be a patch release to fix this issue. However, this seems to be working fine for us right now after the 6.2.2 upgrade."

"The stability is okay, but sometimes we see that the memory on the server is not 100 percent correct and we need to stop and start the software to have it reallocated again."

"Another thing that would help out is if they packaged the NetFlow monitor into nGeniusONE. Their NetFlow monitor works with nGeniusONE where you can actually get the netflow of pretty much anything you hook it up to. But it's a separate box that you have to buy. If there was a way that could package that into nGeniusONE, it would be a complete package straight out of the box."

"Before an attack starts, seeing the traffic behavior and activities would be great. The tool should also share alerts since it is an area where the product has certain shortcomings."

More NETSCOUT Network & Application Observability cons

Pricing and Cost Advice

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

"The solution is cheap."

"The solution is free to use."

"It's an open-source solution."

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

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

"Their pricing is very competitive with other solutions... But what I like about NETSCOUT's licensing is that it's shared across all their platforms. They don't create a new licensing scheme for every one of their products. So for nGeniusONE, you buy a certain license level, and it works on all of their products."

"I would like it to be more scalable with less spend."

"The license becomes cost prohibitive very quickly."

"I rate the price of NETSCOUT nGeniusONE a four out of five."

"The scalability becomes very expensive quickly."

"It can be scalable. It just costs too much. With a company as big as ours, it gets too expensive to accommodate every single site."

"There is a need to make yearly payments towards the licensing charges attached to the product. The product may come across as a cheap tool for some, while it may seem costly for others."

"Like any company, we always want better pricing. The pricing is okay, but it's not a cheap solution. When you want to deploy it across an enterprise as large as ours, you go into seven figures. It's not a cheap solution to get out there."

Which is the best DDoS protection solution for a big ISP for monitoring and mitigating?

I would say if it’s an ISP that will build a scrubbing center, Netscout/Arbor is a good solution. In all other solutions, Imperva is a great choice.
