Luis Gabriel Mieles Benavides - PeerSpot reviewer
Cloud Architect at Sonda S.A.
Security monitoring has become proactive and threat hunting is now faster and more precise
The best features of Microsoft Defender for IoT are that it is easy to find where the intruder is and easy to capture and hunt intruders. When I need to send a full scan for a device, it is straightforward. I have worked with Symantec, which is an antivirus, and McAfee, where I send full scans in a similar way to how I do it in Azure Defender, and it is equally easy. I can take actions with the device, such as disconnecting it, turning it off, or sending an alarm. The integration with Azure Defender and Azure Sentinel is seamless because they are from the same company. They capture intruders, viruses, worms, and everything else easily, and I can fix problems quickly. I use the network visibility features daily to manage connected assets. Currently, I am closing a case with Mutual Asesorías where they have a computer with intruders attempting to force brute capture the password. I can see how the intruder tried to do this, and my work involves closing the IP origin in this case.

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

"The best features of Microsoft Defender for IoT are that it is easy to find where the intruder is and easy to capture and hunt intruders."
"The graphics and analysis in Microsoft Defender for IoT are very representative."
"I believe it is best suited for cloud services and is unmatched by other cloud security solutions."
"Some advantages of Microsoft Defender for IoT are that it's easy to install on any OS, and you can create any custom use cases easily."
"I find Microsoft Defender very effective in vulnerability management and it provides good attack reduction, making it a next-generation protection solution."
"Mainly, it is manageable and integrates with other Microsoft products, which is crucial for me."
"As a cybersecurity consultant, the best part of Microsoft Defender for IoT is the capability to integrate with other tools such as Microsoft Sentinel and receive real-time alerts from the product."
"I believe it is the best."
"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."
"Our last customer using Nozomi Networks is very happy with it and appreciates the reports and all features, and they use Nozomi Networks in the SOC where the technical people monitor and see the performance of the OT product and are very satisfied."
"Nozomi Networks has really offered a stellar performance within the organization and there is not any specific part that needs improvement for now."
"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."
"This is a good product and I definitely recommend it."
"The return on investment from Nozomi Networks is substantial, particularly concerning time saved."
"The feature I like best is its stability."
 

Cons

"The only improvement I see is that some detection explanations are vaguely provided by Microsoft, resulting in generic IoT detections that alert me to an issue yet don't specify what's wrong."
"Microsoft Defender for IoT is not scalable. If you want to monitor another industrial network, you need an additional server, making it less scalable."
"There are a few limitations with Microsoft Defender for IoT. We raised concerns with the product team because they don't capture all the information regarding command execution or processes executed on certain endpoints."
"The primary area that needs improvement is compatibility with the latest IoT technologies."
"Customer service and support from Microsoft are costly. The execution by engineers is expensive, and the service is neither free nor toll-free, making it less accessible for customers."
"The documentation for Microsoft Defender for IoT is lacking. There are no clear steps or guidance, and updates are frequent, which adds to the confusion."
"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."
"I chose eight out of ten because their customer services are something lacking."
"On the negative side, I believe their AI, which is IQ, could be more improved."
"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."
"To improve Nozomi Networks, I believe that it is less useful without Vantage if I have a multi-site setup."
"The main challenge with mapping Nozomi Networks for asset inventory was the new integrations."
"The solution should include an integration library."
