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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I find Microsoft Defender very effective in vulnerability management and it provides good attack reduction, making it a next-generation protection solution."
"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."
"The graphics and analysis in Microsoft Defender for IoT are very representative."
"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."
"Mainly, it is manageable and integrates with other Microsoft products, which is crucial for me."
"I believe it is best suited for cloud services and is unmatched by other cloud security solutions."
"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."
"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' best features include asset management as the top offering, providing a wide range of capabilities, along with vulnerability management backed by a very large and regularly updated PV data bank that provides the right direction with tested patches, plus financial calculations and reports based on NIST and other frameworks, all supported by a dashboard that delivers better visibility and sets Nozomi Networks apart from others."
"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."
"Nozomi Networks has positively impacted our organization as we can visualize the traffic within the OT networks and identify the potential threats or vulnerabilities."
"The best feature of Nozomi Networks is that it has built OT-oriented protocols such as OPC UA, DNP3, Modbus, and Siemens S7, and for these protocols, Nozomi Networks identifies them very perfectly."
"The scalability of Nozomi Networks is super easy to scale up as long as you have a Vantage solution, meaning the private cloud connected to on-premises or on-premises Guardians connected to the private Nozomi Networks cloud."
"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."
"Nozomi Networks is an easy-to-use and powerful tool."
 

Cons

"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."
"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 documentation for Microsoft Defender for IoT is lacking. There are no clear steps or guidance, and updates are frequent, which adds to the confusion."
"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."
"The pricing was quite high based on the end customer's perspective."
"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."
"On the negative side, I believe their AI, which is IQ, could be more improved."
"Nozomi Networks can be improved by integrating with other technologies so that teams look at a single dashboard when it comes to security issues."
"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."
"Integrating with other security devices is a little difficult because this process is not currently automated."
"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."
"To improve Nozomi Networks, I believe that it is less useful without Vantage if I have a multi-site setup."
