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.

An affordable and easily scalable tool that decreases the risk of data leakage in an organization

It is important to me that Purview delivers data protection across multi-cloud and multi-platform environments. Otherwise, we would have to have multiple DLP solutions. It is very important to me that the solution was built taking into account critical regulations from around the world. It makes it easier to templatize deployments for data loss prevention. I use the tool for data loss protection. The tool works fairly well in remediating policy violations. There could be a little bit of improvement in policy tips. Policy tips aren't consistent across different experiences. The tool has greatly impacted the visibility of most of our customers. Some of our customers didn't realize they had a lot of PII data being sent externally until after the tool was implemented. Later, they become more aware. The solution enables us to show our compliance as close to real-time as possible. It has affected our meetings with compliance regulators. We don't save time and money directly. The tool saves us time and money by saving on fines for regulatory compliance violations. Without the solution, one of our customers would have been fined about $2,500,000. It is important to me that the product can connect to iOS, Mac, and Android devices, as well as data in other SaaS apps. It's not a complete solution unless it can be used everywhere. We are implementers. People evaluating the product must understand the types of data and the compliance models they must adhere to. Overall, I rate the product an eight out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"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."

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

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

"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."

"For Purview's natively integrated compliance across Azure, Dynamics 365, and Office 365, I would give it a 10 out of 10. It provides all the insights and information."

"Insider risk management and data retention are beneficial."

"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."

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

"Microsoft Purview Data Loss Prevention's ability to prevent unauthorized sharing of sensitive information is valuable."

"Microsoft Purview Data Loss Prevention's responses are faster. Its installation is also reliable. The security score helps with the security part."

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

"The auto-labeling feature is definitely the most valuable feature. It goes in and labels the documents for you in different repositories. It covers the Outlook and Exchange repositories along with SharePoint and OneDrive. It is really helpful in those areas."

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."

"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."

"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."

"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 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."

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

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

"Endpoint Data Loss Prevention needs to be improved as it is not up to expectations."

"Some main features are limited in comparison to other solutions."

"The support is poor."

"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."

"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."

"The solution should provide better integration with other systems."

"Microsoft Purview Data Loss Prevention's licensing is expensive."
