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.

"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."

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

"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."

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

"The product has improved compliance and confidence. We are aware of the data that is leaving our organization. It provides confidence in data management and information storage."

"There's a good amount of documentation in case you run into any problems."

"The impact of Microsoft Purview Data Loss Prevention's classification and policy controls on our productivity within our organization is significant, as it's helped our security team."

"The product can block the uploads to cloud services."

"Because everything is on Microsoft and we use Azure, integration with the product is easier. That's the most important thing when you use many Microsoft products. It's easier to integrate everything in one place."

"Earlier, our customers had no control at all over compliance, and confidential documents that were going out were not at all looked into, and Microsoft Purview Data Loss Prevention has been a huge benefit to our clients in this regard."

"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."

"My favorite feature about Microsoft Purview Data Loss Prevention is actually quite simple: there's a handful of things that you do, you create a new batch, it'll give you a unique ID, you copy that unique ID, it's a URL, and then you can put that into a script that we wrote so we just paste that in our script and then it uses that URL to upload all of those mailboxes, and then we can use that to import."

Cons

"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."

"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."

"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 documentation for Microsoft Defender for IoT is lacking. There are no clear steps or guidance, and updates are frequent, which adds to the confusion."

"I see that there's a lot of content in Microsoft Purview Data Loss Prevention, and when I click on it and look around, I wonder what certain features do, but there's not enough documentation and explanation."

"They do not provide language options beyond the ones already available, so our language option is missing."

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

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

"All the security operations are better defined in Forcepoint, while in Microsoft Purview Data Loss Prevention, you will have to use a specific workflow and then an application to release blocked emails."

"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."

"A major improvement is required in the solution's incident handling and alerting."

"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."

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."

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

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

"Microsoft Purview Data Loss Prevention is part of a bundle and is not sold as a standalone product."

"The solution’s pricing is reasonable."

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

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

"The pricing is reasonable."
