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.

Easy to integrate, enhances operational efficiency, and has machine learning capabilities
We are satisfied with the product. We can passively scan the network for anomalies and let it learn through machine learning about the normal state of the network. If it deviates from that, then it is an anomaly. It would give an alert about anomalous behaviors like a cyber attack. The network visibility has enhanced operational efficiency. It is easy to integrate the solution with the existing industrial control systems.

"Nozomi Networks is an easy-to-use and powerful tool."
"The tool's visibility is good. We can see the traffic flow."

"There is definitely a notable return on investment from Nozomi Networks, including financial savings and time efficiency."

"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."

Cons

"Nozomi Networks pricing is very high."
"The main challenge with mapping Nozomi Networks for asset inventory was the new integrations."

"Nozomi Networks can be improved by integrating with other technologies so that teams look at a single dashboard when it comes to security issues."
"The pricing was quite high based on the end customer's perspective."
"I believe there is room for improvement regarding on-premises AI."
"To improve Nozomi Networks, I believe that it is less useful without Vantage if I have a multi-site setup."

Pricing and Cost Advice
