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.

Comprehensive security features with integral network communication view
Real-time monitoring and proactive threat prevention offered by Palo Alto Industrial OT Security is a key feature of the product, which is distinctive since many other security solutions for industrial plant environments are basically able to detect - not protect. They need to be integrated with other security components, making the deployment more complex as more products and solutions need to be integrated. In Palo Alto, we have a single device that does everything. These features contribute to maintaining oversight over my Industrial networks or my customers' networks, and it's very important. It is a way to detect any change in the field, even if changes are made outside the proper control processes. The capability of Palo Alto Industrial OT Security to map network flows and understand asset interdependencies is especially important in complex environments. In smaller environments, which are the most common in my country, the industrial plants usually change very slowly, so this kind of discovery feature is interesting at the beginning but not critical after the first deployments. The positive impact of Palo Alto Industrial OT Security on my organization brings benefits such as a constant view of the intercommunication and connection between different areas of the networks.
