Has a learning curve that is easy to deal with for users

With the tool, the learning curve is really good. I don't have to spend time in long training sessions, which is typically required for other platforms. As my company is a Microsoft kind of shop, we have developers, making the learning curve easy compared to other tools. When it comes to integration with the back-end systems, manufacturing companies are still using some other apps in their environment. Getting data or pushing those analytics data back to the back-end systems is relatively simple while using Azure Sphere and other integration points, and so that is why there is a clear direction from our company's end customer that they need an Azure solution.

Comprehensive dashboards have enabled detailed asset visibility and proactive risk mitigation

On the negative side, I believe their AI, which is IQ, could be more improved. For example, when I export any data, there are only 50 columns available. What if there were more columns? Nozomi Networks does not provide that data, so I have to go to the query section. The AI is currently useful for writing queries in English that are converted into their coding language for queries. Sometimes it provides the correct data, and sometimes it does not understand the request. From my attempts, I would say 50 percent of the time it has given me the proper data, and 50 percent of the time it might need improvement. Every day or week, new threat intelligence and AI upgrades are being released for Vantage, and all those upgrades are being implemented. Things are getting better, but I believe there are areas of improvement.

Quotes from Members

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

Pros

"I think my team is comfortable with the installation of the product."

"When you use this solution, you get a dual processor with all the necessary security and Microsoft updates supplied, so you don't have to be concerned about the security aspect related to IoT because Microsoft takes care of this."

"It's stable and the performance has been great."

"This is a good product and I definitely recommend it."

"It brings visibility into the OT environment because most of the enterprises only have methods to check their IT environment."

"The best feature of Nozomi Networks is that it has built OT-oriented protocols such as OPC UA, DNP3, Modbus, and Siemens S7, and for these protocols, Nozomi Networks identifies them very perfectly."

"Nozomi Networks' best features include asset management as the top offering, providing a wide range of capabilities, along with vulnerability management backed by a very large and regularly updated PV data bank that provides the right direction with tested patches, plus financial calculations and reports based on NIST and other frameworks, all supported by a dashboard that delivers better visibility and sets Nozomi Networks apart from others."

"Nozomi Networks has positively impacted my organization by allowing me to build a roadmap based on what I see, ultimately leading to a better security posture, which includes knowing what is inside the network and what vulnerabilities exist."

"Our last customer using Nozomi Networks is very happy with it and appreciates the reports and all features, and they use Nozomi Networks in the SOC where the technical people monitor and see the performance of the OT product and are very satisfied."

"The return on investment from Nozomi Networks is substantial, particularly concerning time saved."

"The most valuable feature of Nozomi Networks is its security features."

Cons

"The lack of awareness of the products among our company's customers is a challenge that needs to be looked at and improved by Microsoft."

"The type of edge devices being addressed through the suite was limited, however, even that has also significantly increased."

"One of the pain points of this solution is that the full Linux box is not exposed to all developers. This restricts what the applications can do as they cant be adjusted."

"I see challenges with Nozomi Networks mainly as a detection or visibility tool, but it does not actively block traffic by design for safety reasons."

"Nozomi Networks currently offers add-ons, such as ARP agents, that can be installed on machines to expand the information we receive from sensors. However, these are part of a licensing structure, which can be costly."

"I chose eight out of ten because their customer services are something lacking."

"Integrating with other security devices is a little difficult because this process is not currently automated."

"Nozomi Networks should improve its pricing."

"I believe there is room for improvement regarding on-premises AI."

"I think Nozomi Networks should still work on the graphical user interface because it can be more friendly in terms of user experience, especially regarding the flows, the workflows, the intuitiveness of certain things and positions of certain buttons or even creating a dashboard for yourself in a way easier manner."

"Nozomi Networks can be improved in many points. First of all, reduce the cost. That is really important because many companies are not so huge and many companies cannot acquire this kind of licensing."
