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.

Quotes from Members

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

Pros

"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."
"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."
"I find Microsoft Defender very effective in vulnerability management and it provides good attack reduction, making it a next-generation protection solution."
"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."
"Mainly, it is manageable and integrates with other Microsoft products, which is crucial for me."
"We can use Microsoft Purview Data Loss Prevention to manage devices and site policies."
"We can triage based on quick and sometimes constant alerts."
"Microsoft Purview Data Loss Prevention makes it way easier to prevent unauthorized sharing of sensitive information within the organization."
"I rate Microsoft Purview Data Loss Prevention's stability a ten out of ten."
"Insider risk management and data retention are beneficial."
"When you are going to use Microsoft Purview Data Loss Prevention, most of the setup is already done by default as per your needs."
"The most valuable features are identifying sensitive data and issuing alerts."
"Microsoft Purview Data Loss Prevention's responses are faster. Its installation is also reliable. The security score helps with the security part."
 

Cons

"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 primary area that needs improvement is compatibility with the latest IoT technologies."
"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."
"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 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 Purview Data Loss Prevention's licensing is expensive."
"I rate the overall solution 3 out of 10."
"The major challenge we had was overreach. When our initial design inception blocked more data than we expected, we had a lot of help desk related issues that we did not see in testing."
"More training for end users on how it works would be beneficial."
"The main disadvantages of Microsoft Purview Data Loss Prevention in comparison to the Netscope product are notable considerations."
"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 assess the stability and reliability of Microsoft Purview Data Loss Prevention as being flaky at times, where eDiscovery sometimes takes forever or doesn't bring the results we expect."
"Endpoint Data Loss Prevention needs to be improved as it is not up to expectations."
 

Pricing and Cost Advice

Information not available
"I am satisfied with the tool's pricing."
"The solution’s pricing is reasonable."
"The cost works out to about $15 per user per month."
"The pricing is reasonable."
"Though I am not a specialist, the tool is quite expensive."
"We are using the E3 license for Microsoft 365 with the E5 compliance license add-on."
"It's a little bit pricey compared to competitors, but it's not too high."
"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."
