Integration with existing tools boosts management efficiency

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. Often, it just links back to a generic KB article without additional information. When it happens, it requires extra detective work. This issue doesn't occur often but can be annoying.

Automation has given us consistent analytics and improved quality of insights into user activity

One of the valuable features of Purview is the ability to create a legal hold on a user's account within the compliance portal. That's pretty useful when it comes to any litigation or if you want to redeem the content within a mailbox, OneDrive, or a generic public SharePoint site. If you want to retain the user's data until the case is resolved, you can use the legal hold feature. Also, it's important that Purview can connect to iOS, Mac, and Android devices. With smartphone involvement, so many applications can now be accessed through them and it is important to apply Purview across operating systems and platforms. Purview's natively integrated compliance across Azure Dynamics and Office 365 is also significant because within Microsoft 365 there are multiple applications. Irrespective of whether it's Dynamics or Azure, it's very important that it has native support. The data connectivity should be efficient enough to support and secure their own platform's data. In addition, with varying regulations in different industries and matters, Purview lets you create rules and conditions based on industry standards around the world. That is important. Our company is in pharmaceuticals and the rules and conditions are different from other industries. It is important to be able to keep track of all these regulations and have a tool that is flexible enough to create the regulatory rules and conditions we need. And when it comes to data loss protection, Purview has features that can recognize patterns and detect any sort of data loss, where the data is being transferred from its platform to a different one. The default settings that come with it are pretty nice for identifying data transfer or data loss across the platform. It also comes with a lot of training materials, with use cases and examples, to help educate users and make them familiar with the tool.

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."

"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 primary area that needs improvement is compatibility with the latest IoT technologies."

"I would like Microsoft Purview Data Loss Prevention to be on the source code or SQL databases. It is difficult to do classification and labeling when you have a third-party source code or a third-party Oracle database. It is seamless when it comes to Microsoft documents but is not so with third-party source codes. Microsoft needs to work on it a little bit more."

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

"There is a need for improvements, particularly in ensuring that file-based recognition is more reliable and comprehensive."

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

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

"All the security operations are better defined in Forcepoint, while in Microsoft Purview Data Loss Prevention, you will have to use a specific workflow and then an application to release blocked emails."

"Technical support is awful."

"We faced a performance issue with the tool when we didn't get alerts for file uploads."

Pricing and Cost Advice

Information not available

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

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

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

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

"The pricing is reasonable."

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

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