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.

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."

"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."

"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."

"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."

"Before using it, we had a lot of unlabeled data, and the tool helped us quickly and accurately label a large number of documents."

"Purview saves customers time by offering them a quick way to assess a situation and insights into how to improve."

"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."

"The features I like the most about Microsoft Purview Information Protection include the ability to set different retention policies, which have benefited my organization by being crucial in maintaining taxpayer anonymity when communicating with government employees."

"The feature I prefer the most is the automated controls around it, such as automated labeling, which is effective."

"My favorite feature about Microsoft Purview Information Protection is how it applies to everything generally, so I don't have to do it manually."

"The user interface is nice and it's very user-friendly on that front."

"The simplicity of the way we can configure the DLP rules in Microsoft Purview Information Protection is good."

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 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."

"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."

"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."

"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."

"Most of the capabilities they mention are not working as expected. That is where the challenge lies."

"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."

"Microsoft Purview Information Protection can improve in terms of scan concurrency and scan processing time."

"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."

"I see many options such as SharePoint Advanced Management for customers, but that requires a high investment from the customer's end in order to access the premium features of Purview, so it is not easy."

Pricing and Cost Advice

Information not available

"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."

"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 pricing and setup costs are transferred to my clients, who find it affordable and are satisfied with what they receive."

"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."
