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.

Pros

"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."
"Mainly, 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."
"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 graphics and analysis in Microsoft Defender for IoT are very representative."
"I find Microsoft Defender very effective in vulnerability management and it provides good attack reduction, making it a next-generation protection solution."
"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."
"Purview is about auditing and discoverability. We need to ensure people aren't releasing information that they shouldn't and that they're doing multi-factor authentication or accessing it from the correct devices. It aids in reducing silos within organizations, enabling staff to easily find documents and contacts without exhausting human resources."
"I created training materials for end users on applying different labels, explaining their purposes, and providing examples. This was crucial since end users would apply the labels in different protection scenarios. The implementation helped the organization in several ways."
"Microsoft Purview Information Protection integrates with the productivity and security tools that my customers use regularly, allowing them to avoid using multiple information protection solutions."
"The simplicity of the way we can configure the DLP rules in Microsoft Purview Information Protection is good."
"The user interface is nice and it's very user-friendly on that front."
"I think Purview is incredibly stable."
"We are using Microsoft Purview Information Protection to enable the confident use of AI, so it is a set of controls and visibility that helps customers understand why they should be confident in the way that they have organized and classified their data so they can start to let agentic AI operate in their environment."
"The reporting capabilities of Microsoft Purview are crucial. They provide insights into potentially non-compliant situations and suggest ways to rectify them. The solution helps to automate many tasks, allowing human operators to focus on areas where they offer the most value."
 

Cons

"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."
"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."
"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."
"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."
"Microsoft Purview Information Protection can improve in terms of scan concurrency and scan processing time."
"There is room for improvement with the policy tips feature."
"I would like the time it takes to update a DLP policy on an endpoint to be reduced."
"Scalability is affected by the time it takes to update policies."
"Our primary concern is third-party application visibility. Many people choose other DLP tools, as they can search the Office 365 suite and detect sensitive information across thousands of other apps. The product is weak compared to the competitors on the DLP front, but the classification is good; the tool needs a bit more maturation."
"During the initial setup, I found the lack of policy segregation at the sub-site level for DLP policies to be a challenge."
"Microsoft can improve the affordability of Purview Information Protection by offering it at a lower cost."
 

Pricing and Cost Advice

Information not available
"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 price is determined by the enterprise licensing, either the E3 or E5 licensing or the EMS plus security and other feature licensing."
"The tool's pricing is fairly low, less than 100,000 for a year."
"The pricing and setup costs are transferred to my clients, who find it affordable and are satisfied with what they receive."
"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 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."
