Security monitoring has uncovered unauthorized devices and now protects client networks
I think the best feature of Armis Centrix for OT/IoT Security is that it ensures only the authorized devices and users are authorized to prevent any potential breaches. I think that clear definition is very essential for a lot of networks because it helps us understand who should be there and who shouldn't be. For our clientele, we were able to discover a lot of unauthorized devices that were on their network. This first of all helped them remove a lot of potential security breaches and cleared the bandwidth of the network as well. I think this has been one of the biggest cases that we have found. For most of the clients where we have deployed it, this has always been a common occurrence because a lot of people enter the network and then you don't know who is there, who has the access, and so on. I think this is the very reason I said what I said earlier.

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.
