Effective asset management improves OT security by quantifying risks and identifying unauthorized communications
What is our primary use case?
We use Nozomi Networks in our operational technology environment to manage the inventory of assets in our plants and conduct vulnerability assessments and risk quantification. It helps us identify communication that is not allowed between zones.
What is most valuable?
The most valuable features of Nozomi Networks are the visibility of OT protocols and the versatility in finding the details of the assets feeding the tool. It is helpful because we can see all the traffic coming from the plants. We can distinguish what kind of traffic is our baseline, what is different from normal operation, and what is traversing the OT zone to the IT zone.
What needs improvement?
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. It would be very helpful if these agents were available free of charge. The solution itself has no major problems, but this is a feature request I would make for improvement.
For how long have I used the solution?
I have had experience with Nozomi Networks for three years.
What do I think about the stability of the solution?
I would rate the stability of Nozomi Networks as a nine out of ten. It is very good.
What do I think about the scalability of the solution?
Scalability is straightforward and tied to the license. We have a batch of 5,000 assets, but deploying the Guardian solution is unlimited. We can install the software image anywhere in any plant and still receive information.
How are customer service and support?
I would rate their customer service at eight out of ten. While their support is good, we are looking for added value in a provider. I would like to see more proactive communication and campaigns from them to help us gain further benefits and visibility of the product features.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
We previously used Tenable OT Security. We switched to Nozomi Networks due to price and architecture. Scalability is easier with Nozomi Networks, and the reporting part is integrated with the tools, unlike in Tenable, where it was separate.
How was the initial setup?
The initial setup was very easy. We have a solution called Vantage licensed by assets. We manage 5,000 assets and deploy the tool with Nozomi Networks software. We only need to connect a span port or mirror port from the network to start receiving information.
What's my experience with pricing, setup cost, and licensing?
Nozomi Networks is priced moderately. Its cost is not too expensive, but it is not low either.
What other advice do I have?
Nozomi Networks scores a nine out of ten overall. There is no perfect solution, but it is a solid choice for managing OT security.
Which deployment model are you using for this solution?
Public Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

How would you rate customer service and support?
Positive
How was the initial setup?
The solution's deployment is easy and requires only two days.
What was our ROI?
The platform's impact is significant because it provides a clear vision of all devices, including non-standard ones. Usually, customers have no idea about their environment, machines, or operations, making it very difficult to achieve visibility across all devices in the network. This is the main scope of the platform.
There are noticeable cost savings for a company after implementing Nozomi Networks. With this solution, fewer technical resources are needed, and the people managing the data center or environment have fewer daily activities to handle. A robust security solution means fewer tickets to manage and more precise security. This leads to less configuration needed on network devices or firewalls. These are the main benefits of implementing this solution.
What other advice do I have?
The operational and technical architects, NOC, and SOC teams usually use nodes to detect and remediate firewall issues. They prefer not to analyze the environment more deeply. Instead, they rely on alerts about threats or suspicious, malicious traffic flow in their network devices.
I would recommend it because it is easy to install and develop. It provides a deep analysis of devices, which helps manage security reviews and ensure compliance. Overall, it is a good solution for these main purposes.
I rate the overall product a nine out of ten.
