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.

Critical networks have gained real-time visibility and detect threats with intelligent monitoring
I would like to see improvements in Nozomi Networks, probably more AI-based integration and better native integration with SOC and SOAR platforms. I would like to see specific features included in the next releases of Nozomi Networks, such as improvements in threat intelligence. They have competition from Dragos, which I believe is better in threat intelligence. I do not have much of an answer about the key differences of Nozomi Networks in comparison to other cyber defense solutions because I only work with Nozomi Networks. However, I heard from the market that they might lack in threat intelligence compared to Dragos. Other than that, I see Nozomi Networks as the best platform for customers, easy to manage, deploy, and operate. The cons might be that they lack some threat intelligence features that Dragos offers.

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."
"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."
"Microsoft Defender for IoT is not scalable. If you want to monitor another industrial network, you need an additional server, making it less scalable."
"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."
"The primary area that needs improvement is compatibility with the latest IoT technologies."
"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."
"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."
"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."
"Creating custom queries is time-consuming."
"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."
"The solution should include an integration library."
"I believe there is room for improvement regarding on-premises AI."
"I would like more customizable options for configurations."
"It should support more programmable logic controllers (PLCs)."
