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.
