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.

"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."

"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."

"It is manageable and integrates with other Microsoft products, which is crucial for me."

"Mainly, it is manageable and integrates with other Microsoft products, which is crucial for me."

"Microsoft Purview Data Loss Prevention has absolutely helped improve my organization's ability to manage data because we use M365 for the majority of our knowledge worker storage, and that's where people's data lives."

"It has helped our clients to reduce the time to action on insider threats because it can be integrated."

"Microsoft Purview's classification and policy controls impact users' productivity within my organization very positively, as it does not get in the way of their working."

"Microsoft Purview Data Loss Prevention's responses are faster. Its installation is also reliable. The security score helps with the security part."

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 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."

"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 tool's user interface and document fingerprinting have been very poor for my customers because uploading files manually can be problematic."

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

"I would say the improvement of Microsoft Purview Data Loss Prevention could be in the propagation of policies, as if you create a policy, it may take up to 48 hours to propagate to devices, and this might take a little bit longer than ideal."

"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."

"There is a need for improvements, particularly in ensuring that file-based recognition is more reliable and comprehensive."

"A site can have different containers where you store data. We have always wanted to apply compliance, labels, and policies at the container level, rather than to an outer shell or at the site level. That is something we have been looking forward to and I believe Microsoft is already planning something like that."

"I would like Microsoft Purview Data Loss Prevention to be on the source code or SQL databases. It is difficult to do classification and labeling when you have a third-party source code or a third-party Oracle database. It is seamless when it comes to Microsoft documents but is not so with third-party source codes. Microsoft needs to work on it a little bit more."

"It could cover more solutions and technologies."

Pricing and Cost Advice

Information not available

"The product has the best price-to-performance ratio."

"It is a part of our Microsoft licensing. We pay for a yearly renewal. Its price is reasonable for the size of the organization we are. It is fairly competitive, and you get what you pay for. We have an E5 license, and a part of understanding the E5 license is to see what all you get with it. If you really look at it from that standpoint, you get a lot of value. You have Defender and all its security features in there as well. Their licensing is fairly flexible. They have different programs. We've seen ones where you could pay for up to three to five years in advance. There is also a monthly pay-as-you-go type of deal, but we're doing a yearly renewal and fixing the budget."

"The cost works out to about $15 per user per month."

"You get the solution in a bundle if you get the E5 suite."

"We are using the E3 license for Microsoft 365 with the E5 compliance license add-on."

"I am satisfied with the tool's pricing."

"If one is very cheap and ten is very expensive, I rate the price as one out of ten."

"The solution’s pricing is reasonable."
