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.

Integrated controls have reduced insider risk and now protect sensitive data across our workforce
One standout feature about Microsoft Purview Data Loss Prevention is the tight integration with Insider Risk Management and Defender XDR, as it gives much better context during investigations instead of treating DLP as an isolated alerting tool. We also use endpoint DLP heavily to control USB, copy, print, clipboard, and browser upload activity, which has been very effective for remote workforce security. The best features Microsoft Purview Data Loss Prevention offers include real-time policy enforcement, endpoint DLP, and deep integration with Microsoft 365 plus Defender XDR. We also heavily rely on sensitive information type detection, adaptive policy tips, and insider risk integration to investigate suspicious user behavior with proper context. Another standout feature is the ability to control USB copy, browser uploads, print clipboards, and cloud sharing actions directly from endpoint policies. The integration with Microsoft Defender 365 and Defender XDR helps our team in day-to-day operations because DLP alerts are automatically correlated with endpoint identity, email, and user activity telemetry, which helps the SOC investigate incidents much faster from a single workflow. The sensitive information type detection makes a difference compared to other tools we have used because it is more effective than many legacy DLP tools. It understands context, exact data patterns, document labeling, and Microsoft 365 native content, reducing false positives while improving detection accuracy. Another strong feature of Microsoft Purview Data Loss Prevention is auto-labeling and policy inheritance with Microsoft's Information Protection, which helps maintain protection even after files are shared or moved across workloads. We also value the user coaching or policy tip capability because it educates users in real time instead of only blocking actions, which reduces repeated DLP violations significantly.

Pros

"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."
"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."
"I find Microsoft Defender very effective in vulnerability management and it provides good attack reduction, making it a next-generation protection solution."
"Mainly, it is manageable and integrates with other Microsoft products, which is crucial for me."
"The graphics and analysis in Microsoft Defender for IoT are very representative."
"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."
"Microsoft Purview Data Loss Prevention has significantly improved our data security posture by reducing the risk of accidental data leaks and helping to meet compliance requirements."
"The most valuable features are identifying sensitive data and issuing alerts."
"We can triage based on quick and sometimes constant alerts."
"If we can prevent information from going out, eventually, when a regulator is asking about our security measures, we can show what we've been doing."
"We can use Microsoft Purview Data Loss Prevention to manage devices and site policies."
"Microsoft Purview Data Loss Prevention has impacted the organization very positively by strengthening data security through automatically detecting and protecting sensitive information across emails, endpoints, SharePoint, and OneDrive."
"The solution is very stable and extremely reliable."
"The solution's most valuable feature is the mature O365 DLP, which works with SharePoint and Teams."
 

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."
"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."
"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."
"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."
"I rate the overall solution 3 out of 10."
"Microsoft Purview Data Loss Prevention can be improved as the endpoint DLP policy tuning can be complex in large environments, especially when balancing security with user productivity."
"There is a need for improvements, particularly in ensuring that file-based recognition is more reliable and comprehensive."
"We faced a performance issue with the tool when we didn't get alerts for file uploads."
"Technical support seriously needs work. They are not helpful at all."
"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."
"Improving Microsoft Purview Data Loss Prevention would involve recognizing that the whole AI path we are all on is going to help, given the massive amount of data we handle; even if there are true positives, implementing a degree of severity ranking is essential."
"The only concern is that it forces clients to use an expensive license."
 

Pricing and Cost Advice

Information not available
"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."
"We are using the E3 license for Microsoft 365 with the E5 compliance license add-on."
"If one is very cheap and ten is very expensive, I rate the price as one out of ten."
"The cost works out to about $15 per user per month."
"The product has the best price-to-performance ratio."
"Microsoft Purview Data Loss Prevention is part of a bundle and is not sold as a standalone product."
"Though I am not a specialist, the tool is quite expensive."
"The pricing is reasonable."
