Effective network monitoring with identified documentation improvements needed

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. More detailed documentation with video instructions for tasks would be helpful. The system capabilities are not well-documented either. Importing device names and maintaining a list can be cumbersome, as it requires manual input for a large number of devices. The backup and restore process is limited to GUI for backup but lacks a GUI for restore, though future updates might address this. Sentinel documentation is also poor, with limited guidance available.

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."

"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."

"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."

"Mainly, it is manageable and integrates with other Microsoft products, which is crucial for me."

"It is manageable and integrates with other Microsoft products, which is crucial for me."

"The most valuable features are identifying sensitive data and issuing alerts."

"I rate Microsoft Purview Data Loss Prevention's stability a ten out of ten."

"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."

"When you are going to use Microsoft Purview Data Loss Prevention, most of the setup is already done by default as per your needs."

"The impact of Microsoft Purview Data Loss Prevention's classification and policy controls on our productivity within our organization is significant, as it's helped our security team."

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."

"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."

"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."

"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."

"More training for end users on how it works would be beneficial."

"The AI advancements can improve the false positives."

"The tool's user interface and document fingerprinting have been very poor for my customers because uploading files manually can be problematic."

"I would assess the stability and reliability of Microsoft Purview Data Loss Prevention as being flaky at times, where eDiscovery sometimes takes forever or doesn't bring the results we expect."

"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 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."

"A major improvement is required in the solution's incident handling and alerting."

"I would say the improvement of Microsoft Purview Data Loss Prevention could be in the propagation of policies, as if you create a policy, it may take up to 48 hours to propagate to devices, and this might take a little bit longer than ideal."

Pricing and Cost Advice

Information not available

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

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

"We are using the E3 license for Microsoft 365 with the E5 compliance license add-on."

"The pricing is reasonable."

"It's a little bit pricey compared to competitors, but it's not too high."

"The solution’s pricing is reasonable."
