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

"I find Microsoft Defender very effective in vulnerability management and it provides good attack reduction, making it a next-generation protection solution."
"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."
"I believe it is best suited for cloud services and is unmatched by other cloud security solutions."
"Mainly, it is manageable and integrates with other Microsoft products, which is crucial for me."
"The graphics and analysis in Microsoft Defender for IoT are very representative."
"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."
"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."
"Nozomi Networks has positively impacted our organization by giving us more visibility into our OT network, so now we know what is happening in our OT network and we can find things which were never there before and which we did not know before."
"Nozomi Networks has positively impacted my organization by allowing me to build a roadmap based on what I see, ultimately leading to a better security posture, which includes knowing what is inside the network and what vulnerabilities exist."
"The tool's visibility is good. We can see the traffic flow."
"Nozomi Networks has led to specific outcomes or measurable improvements for my team, including faster response times."
"Nozomi Networks has positively impacted my organization by ensuring my assets remain secure."
"The most valuable feature of Nozomi Networks is its security features."
"Provides security for our operational technology environment for OT and IoT."
"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."
 

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."
"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."
"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 pricing was quite high based on the end customer's perspective."
"Creating custom queries is time-consuming."
"Regarding the functionality of Nozomi Networks, the query syntax is very complicated. The syntax of the queries is very complex, so sometimes you will not get what you want."
"I would like more customizable options for configurations."
"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."
"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 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."
"We have faced downtimes, crashes, or performance issues with certain implementations."
