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.

Quotes from Members

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

Pros

"The scalability of Nozomi Networks is super easy to scale up as long as you have a Vantage solution, meaning the private cloud connected to on-premises or on-premises Guardians connected to the private Nozomi Networks cloud."
"I chose Nozomi because it is far ahead of other competitors, like Curator and Elastic."
"The most valuable features of Nozomi Networks are the visibility of OT protocols and the versatility in finding the details of the assets feeding the tool."
"The tool's visibility is good. We can see the traffic flow."
"Nozomi Networks has the best AI-based detection and intrusion detection solution, as it is very robust, easy to deploy, and easy to use with a very user-friendly GUI and good support in terms of product and after-sales support."
"Nozomi Networks has led to specific outcomes or measurable improvements for my team, including faster response times."
"Nozomi Networks has impacted my organization positively because we have experience with a few other vendors, and their configuration, reliability, and even threat identification are significantly lower than Nozomi Networks capabilities."
"The return on investment from Nozomi Networks is substantial, particularly concerning time saved."
"The network visibility has enhanced operational efficiency."
 

Cons

"In terms of improvements for Nozomi Networks, I believe clients have mentioned experiencing alert fatigue due to the high volume of notifications once they install the system in a previously unmonitored OT environment."
"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."
"I would like more customizable options for configurations."
"Regarding the functionality of Nozomi Networks, the query syntax is very complicated. The syntax of the queries is very complex, so sometimes you will not get what you want."
"Nozomi Networks should improve its pricing."
"I chose eight out of ten because their customer services are something lacking."
"I think Nozomi Networks can be improved by enhancing the size of the boxes and the performance for collecting logs, and of course, the price."
"Integrating with other security devices is a little difficult because this process is not currently automated."
"The tool must provide new features similar to Radiflow."
 

Pricing and Cost Advice

"The solution's pricing is good and cheaper than that of Claroty."
