What is our primary use case?
I have been involved in projects that used Nozomi Networks for Italian companies. At Advance, for example, we used it extensively, but in Italy, it is a brand that is quite expensive for many companies because the majority of the market is composed of small and medium companies, so a budget for Nozomi Networks is not very often available.
When I have used it, I implemented it for OT and IoT environments in public administration in Rome. We conducted a trial and were followed by a Nozomi Networks technician directly here in Italy. Guardian takes all the information that it receives from the appliance that you have deployed, and after you have all the data, you can put it into your SIEM and or SOAR, even if SOAR is not a good idea to have in use in OT and IoT.
In this particular customer, we had more or less 2,000 devices spread all over the city because they follow the traffic and also the parking and the IPTV cameras that are spread around the city in Rome. We deployed one Guardian and two remote devices that catch all the information that arrived from the devices spread all around the city. We conducted this kind of proof of concept in order to acquire and purchase Nozomi Networks instead of some other competitors.
Another case that I have seen was a really interesting demo with my previous company. We created it using Nozomi Networks and also Rapid7 as a SIEM. We managed a really small beer production facility. We simulated a threat actor that was introduced into the farm. After we deployed Nozomi Networks, we showed the people how it works and what the main features of the product are, how it can overview all the nodes using the probes. The probes can send data to one unique central console that is named Guardian. After that, Guardian can send data, raw data to your SIEM in order to process it and have SOC services that can guarantee the complete overview of your infrastructure.
What is most valuable?
Nozomi Networks is the easiest to use, with the capability to build really quickly an overview of your infrastructure. You can have an inventory of all your OT and IoT devices. It is based on a really solid code instead of many other competitors that were born recently. Today, it is recognized as the milestone to follow, the GOAT in this kind of environment.
Really often people do not know what they have put in place in their infrastructure. Especially in OT and IoT, you have to look into the complete environment in order to have a complete inventory. So, Shadow OT, which I have spoken about many times in terms of devices instead of Shadow IT in terms of applications, is a valuable feature.
Starting from scratch, they did not have any kind of tool that takes care of OT and IoT. Starting from scratch implementing Nozomi Networks, people were really happy because they have seen for the first time all their infrastructure. They have seen for the first time the complete inventory of all devices that were spread into their network. Today they are really happy to feel safe and to be sure to have it all under the control of our SOC services.
What needs improvement?
Nozomi Networks can be improved in many points. First of all, reduce the cost. That is really important because many companies are not so huge and many companies cannot acquire this kind of licensing. The second improvement would be to have a much more solid and robust IT solution, something that works like a network detection and response, even if Nozomi Networks was not born for this.
What do I think about the scalability of the solution?
Nozomi Networks is absolutely scalable because you can introduce some other probes into your environment. You can also put some Guardians on-premise or have the SaaS solution that manages everything.

Which solution did I use previously and why did I switch?
I have always tried to sell Nozomi Networks instead of other competitors from Israel, for example, because I trust in this kind of technology. Although Nozomi Networks is not so up-to-date for IT infrastructure, it is used in OT and IoT environments. It is a really good brand.
What about the implementation team?
This kind of appliance is not so difficult to manage and not so specific. The customer is happy because today they have all things under control.
Which other solutions did I evaluate?
I am actually looking at another solution that is named LEX. It is another completely Italian solution and it is much cheaper than Nozomi Networks, but at this moment, it was born as a network detection and response. Now they are also working on OT/IoT protocols, CANbus, and all the other industrial protocols. For the moment, I think that if you have a really solid infrastructure and you are managing a more or less big customer, you have to choose Nozomi Networks.
Another customer was also evaluating another Iranian solution. At this moment, I cannot remember the name, but it is really famous.
What other advice do I have?
Nozomi Networks works like a charm and works as expected. It is interesting to receive data from CTI and organize it in your infrastructure using the AI algorithms that can really save a lot of time for a SOC operator or SOC analyst. The capability is really good.
Nozomi Networks is not as expensive as some other players like Darktrace, even if they do another job, but it is not so cheap either. I think that Nozomi Networks needs to have some discounts, additional discounts for some environments.
SOC analysts are much happier because they already have good and clean data. In this way, they can reduce the mean time to acknowledge and the mean time to detect.
Be sure that the probes are installed in the right network points. That is the most important thing I can advise.
I would rate this product an eight out of ten.
