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.

Pros

"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."
"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."
"Nozomi Networks has impacted our organization positively as we have gained trust from customers in terms of the technology results and everything that the technology brings."
"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."
"The most valuable feature of Nozomi Networks is its security features."
"It brings visibility into the OT environment because most of the enterprises only have methods to check their IT environment."
"Nozomi Networks' best features include asset management as the top offering, providing a wide range of capabilities, along with vulnerability management backed by a very large and regularly updated PV data bank that provides the right direction with tested patches, plus financial calculations and reports based on NIST and other frameworks, all supported by a dashboard that delivers better visibility and sets Nozomi Networks apart from others."
"Nozomi Networks has positively impacted my organization by ensuring my assets remain secure."
"Nozomi Networks has positively impacted my organization by providing observability of the environment and the assets in the OT environment of the shop floor."
 

Cons

"I'm not exactly sure how scalable it is if you're managing multiple locations, but I think it still has some potential for improvement for multiple locations."
"The main challenge with mapping Nozomi Networks for asset inventory was the new integrations."
"We have faced downtimes, crashes, or performance issues with certain implementations."
"Proof of concept could be improved. It could be more tangible to the customer and the end users to have a video presentation or something like that."
"On the negative side, I believe their AI, which is IQ, could be more improved."
"I see challenges with Nozomi Networks mainly as a detection or visibility tool, but it does not actively block traffic by design for safety reasons."
"Nozomi Networks currently offers add-ons, such as ARP agents, that can be installed on machines to expand the information we receive from sensors. However, these are part of a licensing structure, which can be costly."
"Nozomi Networks should improve its pricing."
"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."
