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."

"I find Microsoft Defender very effective in vulnerability management and it provides good attack reduction, making it a next-generation protection solution."

"I believe it is best suited for cloud services and is unmatched by other cloud security solutions."

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

"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."

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

"The tool's most valuable feature is in the area of OCR."

"Because everything is on Microsoft and we use Azure, integration with the product is easier. That's the most important thing when you use many Microsoft products. It's easier to integrate everything in one place."

"If we can prevent information from going out, eventually, when a regulator is asking about our security measures, we can show what we've been doing."

"My favorite feature about Microsoft Purview Data Loss Prevention is actually quite simple: there's a handful of things that you do, you create a new batch, it'll give you a unique ID, you copy that unique ID, it's a URL, and then you can put that into a script that we wrote so we just paste that in our script and then it uses that URL to upload all of those mailboxes, and then we can use that to import."

"The product is easy to configure."

"We can triage based on quick and sometimes constant alerts."

"We can use Microsoft Purview Data Loss Prevention to manage devices and site policies."

"The solution's most valuable feature is the mature O365 DLP, which works with SharePoint and Teams."

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."

"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."

"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."

"The stability and reliability of Microsoft Purview Data Loss Prevention is great. Besides the weird timeframe where it takes a couple hours for a rule to sync and 24 hours to appear for someone, I don't really have an issue."

"At this time, I have not seen a return on investment with Microsoft Purview Data Loss Prevention."

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

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

"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 scalability, in terms of the portal, could be more user-friendly. Sometimes I have faced difficulties in identifying the options."

"A site can have different containers where you store data. We have always wanted to apply compliance, labels, and policies at the container level, rather than to an outer shell or at the site level. That is something we have been looking forward to and I believe Microsoft is already planning something like that."

"It could cover more solutions and technologies."

Pricing and Cost Advice

Information not available

"The solution’s pricing is reasonable."

"The product has the best price-to-performance ratio."

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

"I am satisfied with the tool's pricing."

"It is a part of our Microsoft licensing. We pay for a yearly renewal. Its price is reasonable for the size of the organization we are. It is fairly competitive, and you get what you pay for. We have an E5 license, and a part of understanding the E5 license is to see what all you get with it. If you really look at it from that standpoint, you get a lot of value. You have Defender and all its security features in there as well. Their licensing is fairly flexible. They have different programs. We've seen ones where you could pay for up to three to five years in advance. There is also a monthly pay-as-you-go type of deal, but we're doing a yearly renewal and fixing the budget."

"The cost works out to about $15 per user per month."

"Microsoft Purview Data Loss Prevention is part of a bundle and is not sold as a standalone product."

"If one is very cheap and ten is very expensive, I rate the price as one out of ten."
