Luis Gabriel Mieles Benavides - PeerSpot reviewer
Cloud Architect at Sonda S.A.
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."
"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."
"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."
"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."
"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."
"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."
"The solution's IDM (Indexed Document Matching), EDM (Exact Data Matching), and DCM (Described Content Matching) features have been most effective in identifying and mitigating potential data leaks."
"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."
"Insider risk management and data retention are beneficial."
"Microsoft Purview Data Loss Prevention makes it way easier to prevent unauthorized sharing of sensitive information within the organization."
"We have not seen any sensitive files leave via email, which represents a significant improvement."
"The auto-labeling feature is definitely the most valuable feature, as it goes in and labels the documents for you in different repositories, covering the Outlook and Exchange repositories along with SharePoint and OneDrive, which is really helpful in those areas."
"We can use Microsoft Purview Data Loss Prevention to manage devices and site policies."
 

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."
"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 Defender for IoT is not scalable. If you want to monitor another industrial network, you need an additional server, making it less scalable."
"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."
"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."
"Endpoint Data Loss Prevention needs to be improved as it is not up to expectations."
"It could cover more solutions and technologies."
"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."
"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."
"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 solution should provide better integration with other systems."
"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."
"There is a need for improvements, particularly in ensuring that file-based recognition is more reliable and comprehensive."
