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."

"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."

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

"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."

"For Purview's natively integrated compliance across Azure, Dynamics 365, and Office 365, I would give it a 10 out of 10. It provides all the insights and information."

"The auto-labeling feature is definitely the most valuable feature. It goes in and labels the documents for you in different repositories. It covers the Outlook and Exchange repositories along with SharePoint and OneDrive. It is really helpful in those areas."

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

"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."

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

"I like the sensitivity labels and data security posture management for AI."

Cons

"The primary area that needs improvement is compatibility with the latest IoT technologies."

"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."

"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 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 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."

"Perhaps with the advent of AI, it can be enhanced, especially with organizations that handle and process huge amounts of data."

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

"It could cover more solutions and technologies."

"The platform can be challenging to navigate and has the potential for improvement."

"Because it's an academic institution, we got really excited about the level of granularity we could implement, but that granularity overwhelmed our users."

"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."

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

"The support is poor."

Pricing and Cost Advice

Information not available

"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."

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

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

"The pricing is reasonable."

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

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

"Though I am not a specialist, the tool is quite expensive."
