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

"I find Microsoft Defender very effective in vulnerability management and it provides good attack reduction, making it a next-generation protection solution."

"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."

"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."

"I believe it is best suited for cloud services and is unmatched by other cloud security solutions."

"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."

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

"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."

"When you are going to use Microsoft Purview Data Loss Prevention, most of the setup is already done by default as per your needs."

"We can triage based on quick and sometimes constant alerts."

"It's secure and can be integrated with an existing Forcepoint DLP setup."

"The solution's most valuable feature is the mature O365 DLP, which works with SharePoint and Teams."

"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."

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

"The policy customization feature is very useful, and we have successfully used the auto policy configuration."

Cons

"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."

"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 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."

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

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

"There is no AIP for Linux systems. That's a setback. Another thing it's lacking is libraries to work with Python. It has libraries for C# and C++, for example, but not for Python and, these days, Python is very useful."

"More training for end users on how it works would be beneficial."

"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."

"The AI advancements can improve the false positives."

Pricing and Cost Advice

Information not available

"The solution’s pricing is reasonable."

"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."

"It's a little bit pricey compared to competitors, but it's not too high."

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

"The pricing is reasonable."

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

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

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