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.

Achieve comprehensive data protection with reliable performance and room for enhanced discovery accuracy
The product is still in a growing phase. I could see that many use cases in their product are not capable enough in terms of detecting or protecting. Compared to other products, they are in the middle of bringing their solution up to the mark, so it is not a full-grown solution. They have to get more accurate results in terms of data discovery and classification. The second thing is their support; support from Microsoft takes a lot of time to get a response from their support team. The third thing is their OCR capability is not that great in terms of identifying the documents. We would love to see response times of less than 24 hours. Additionally, there is no way to check the policy's current status in terms of whether it got synced or not. You have to wait and test the use cases after 24 hours or after 48 hours, and once it starts working, then it appears the policy got implemented.

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."
"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."
"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."
"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."
"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."
"We use the solution for our customers' services. It helps identify and protect sensitive data in documents, PDFs, emails, and Teams chats to prevent data leakage. It can detect and block emails containing credit card information sent outside the organization."
"The most valuable feature of Microsoft Purview Information Protection is its ability to respond to sensitive data shared on Teams chat by deleting the message, not just monitoring or logging."
"Microsoft Purview Information Protection supports data classification, sensitivity labels, and data loss prevention."
"The UI is user-friendly, and I have observed that it improves further each year."
"The simplicity of the way we can configure the DLP rules in Microsoft Purview Information Protection is good."
"Before using it, we had a lot of unlabeled data, and the tool helped us quickly and accurately label a large number of documents."
"Incorporating data loss prevention capabilities built into the Microsoft platform to endpoints, such as Windows 10 and Windows 11 computers, can also help prevent data loss and is highly advantageous."
"My favorite feature about Microsoft Purview Information Protection is how it applies to everything generally, so I don't have to do it manually."
 

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."
"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."
"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 primary area that needs improvement is compatibility with the latest IoT technologies."
"I assess its ability to classify data and identify sensitive information as an area where we have not really gotten a lot of progress yet."
"I rate Microsoft support six out of 10. Response times are a challenge. It's hard to be an ambassador for a product when you know it will be hard to get support."
"The communication around Microsoft product names and functionalities can be confusing, like when they combined Office 365 Risk and Compliance with Azure Purview. Then, they added Purview Hub to Fabric, and people thought Purview Hub would do data lineages, but it didn't. It isn't full-fledged Purview. It's just one feature set."
"Scalability is affected by the time it takes to update policies."
"Microsoft can improve the affordability of Purview Information Protection by offering it at a lower cost."
"Microsoft customer service is hit or miss. Sometimes, I get a fast and knowledgeable response, while other times, I've experienced delays and received no resolution."
"Purview could better integrate with third-party tools, but I don't have a specific use case for that because It's currently integrated into the managed services we offer to Microsoft customers using E5 licenses."
"There should be more training and communication regarding new features. I may be missing those communications, but it often seems like changes happen in the Purview portal without notice. Having a roadmap or updates about new releases would be helpful for demonstrating to clients. If things are constantly changing, I sometimes look silly when I log in, and things have moved or changed."
 

Pricing and Cost Advice

Information not available
"The price is determined by the enterprise licensing, either the E3 or E5 licensing or the EMS plus security and other feature licensing."
"The product is affordable, and our clients agree. Sensitivity labels come with the MIP license at an additional $2 a month per user, an excellent deal for auto-labeling capabilities."
"Initially, Purview's cost seemed quite high because it was for personal use. I was scanning a tiny tenant and thinking, "If I extrapolate this to an enterprise-scale tenant, it will be quite costly." However, I talked to people who had compared it to other products on the market, and they're spending five figures to get started. At least, Purview has a free trial, so you can try some of the features early on."
"The tool's pricing is fairly low, less than 100,000 for a year."
"The tool's pricing is not a problem for customers because they often purchase it as part of a bundle. With an E5 license, for example, users get access to the entire functionality. This is one of the main reasons why many customers are choosing Microsoft."
"The pricing and setup costs are transferred to my clients, who find it affordable and are satisfied with what they receive."
