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.

Automated data discovery has streamlined management while configuration remains complex
Compared to Big-ID, Microsoft Purview Data Governance looks complicated to me. I do not feel it has a good user-level UI. The interface feels a little complicated compared to Big-ID. I did not appreciate the configuration part. It felt complex, whereas when I went for a Big-ID demo, the interface looked better and was easier to understand for any user.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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."
"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."
"I believe it is best suited for cloud services and is unmatched by other cloud security solutions."
"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."
"The graphics and analysis in Microsoft Defender for IoT are very representative."
"Data authentication enables us to classify documents based on whether they should be restricted for internal consumption or permitted for external sharing."
"It is pretty early, but the decision to go with this investment was largely driven by the simplification of our information security technology management stack. That is the primary objective. Once you simplify and you have a connected structure, it allows for faster adoption there. It also gives us additional capabilities as we go on using the technology that we are familiar with, and we do not have to depend on outside parties to come in and tell us how to do certain things."
"I don't know if I've gotten much value out of Purview personally, but our security team loves it. Our biggest concern is leakage or theft of our data because we have a lot of PII and stuff that has not been released. We like the insights Purview provides and the way the solution can track and manage things. I'd say that was probably their favorite piece of it so far. From everything the security team has told me, the policy management and DLP features are working spectacularly."
"Microsoft Purview stands out for its automatic data recovery system, which prioritizes critical data for the fastest restoration."
"The cataloging tool is definitely the most valuable... It tells you about all the data you have in your tables, which helps people understand our data. We now know what data we have."
"The data protection feature is vital as it controls who can access data when it moves out of our protected boundary."
"Purview's ability to connect to iOS, Mac, and Android devices is critical."
"The DLP part and the AI related ones are the most valuable features; I mostly appreciate their automated data discovery."
 

Cons

"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."
"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."
"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."
"Two features are unsupported—custom insights and the DLP component—that would be beneficial to me as a consultant and for the customer in terms of security and monitoring. Regarding security, DLP would provide a more granular level of data masking. Custom insights would offer more detailed monitoring and alerts that can notify customers of failures or anything requiring urgent action."
"There are some limitations to the solution with regard to the lineage of data from different systems."
"Because Purview is not a 100 percent data governance solution, it would help if we could pick some of the good capabilities of other products."
"Frequent daily updates from Microsoft can cause interface elements like buttons to appear and disappear, making navigation unpredictable."
"It could reduce pricing to encourage usage."
"There are differences when looking at an incident in the M365 portal versus Purview, and the main one is the advanced hunting. In the M365 portal, you can write KQL queries and fetch data. If that was available in Purview, it would be very good."
"I have some concerns about the separation of roles in Purview from the Microsoft tenant, as well as how they interact with the security portal and endpoint manager."
"The current event-based retention management is very poor."
 

Pricing and Cost Advice

Information not available
"The pricing depends on the client's requirements and the number of applications."
"The price is reasonable because most of our clients already have an E3 license, which makes implementation easy."
"To get the full features of Purview, we currently need E5 enterprise licenses, which are expensive."
"Licensing is frustrating due to multiple modules and licenses. The feature might be available in the console, but it won't work without the proper license, creating confusion."
"It's not cheap. I'm not exactly sure how much our license costs, but it is very expensive."
"Microsoft Purview is a subscription-based service, so we need either an E3 or E5 license to use it."
"Currently, the licensing differs for the governance side compared to the risk and compliance side."
"It is cheap. It is based on consumption. If somebody wants to start using it, the price is definitely cheaper than a tool like Collibra."
