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.

Protects sensitive data across devices and helps address client compliance needs proactively

The reporting in Microsoft Purview Data Loss Prevention is a little easier than most Microsoft portals. I understand the licensing cost, especially if you're a Business Premium or in the SMB world, and a lot of clients run with a Business Premium. That comes with data loss prevention in a manual process, whereas E5 gives automation. Microsoft has said, 'Okay, here's your Microsoft 365 E5 compliance add-on that can go on the Business Premium.' So Business Premium users can get the data loss prevention features of E5, which is fantastic. That was the big point that they were missing, and I'm glad that they actually have an add-on now that makes it possible. So truly, I don't think there's a downside. Maybe more reporting, but that's it.

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."

"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 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."

"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."

"It could cover more solutions and technologies."

"The scalability, in terms of the portal, could be more user-friendly. Sometimes I have faced difficulties in identifying the options."

"We faced a performance issue with the tool when we didn't get alerts for file uploads."

"Endpoint Data Loss Prevention needs to be improved as it is not up to expectations."

"At this time, I have not seen a return on investment with Microsoft Purview Data Loss Prevention."

"The solution should provide better integration with other systems."

"Microsoft Purview Data Loss Prevention's licensing is expensive."

"There is a lot of ambiguity when you are setting up labels, such as sensitive information labels. It is a little daunting at first if you don't have prior knowledge, and there is a little bit of a learning curve for setting up the labels. Some of the setup wizards could be more helpful from an AI perspective. They can streamline the setup through more AI technologies so that you don't have to jump through so many hoops and different menus and dropdowns. It would be useful to have a setup wizard that is more hands-off and engaging for setting up the information type labels. If you tell them this is what we're trying to protect, it should basically start to lead you down that path of best practices. Such a feature would be great."
