Critical networks have gained real-time visibility and detect threats with intelligent monitoring
I would like to see improvements in Nozomi Networks, probably more AI-based integration and better native integration with SOC and SOAR platforms. I would like to see specific features included in the next releases of Nozomi Networks, such as improvements in threat intelligence. They have competition from Dragos, which I believe is better in threat intelligence. I do not have much of an answer about the key differences of Nozomi Networks in comparison to other cyber defense solutions because I only work with Nozomi Networks. However, I heard from the market that they might lack in threat intelligence compared to Dragos. Other than that, I see Nozomi Networks as the best platform for customers, easy to manage, deploy, and operate. The cons might be that they lack some threat intelligence features that Dragos offers.

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.
