Featured Reviews

William Tuleja - PeerSpot reviewer
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.
Peter-Murphy - PeerSpot reviewer
Streamlined data management and improved compliance with efficient document classification
The most valuable feature is data classification retention since I deal with terabytes of data, and managing and monitoring it simplifies the process. Additionally, the system provides a dashboard showing our compliance status, which aids in managing compliance tasks. The compliance score feature allows me to assess and compare our compliance across organizations. I've also noticed efficiency gains, especially in handling subject access requests. Previously, these tasks were manual and time-consuming, but now they are streamlined, reducing the process from weeks to just a day.

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 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."
"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."
"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."
"Integrating add-on licenses, which currently offer additional features at a cost, into the base product would be beneficial, especially for a charity organization to avoid incurring extra costs."
"The speed and accessibility, particularly in the user interface, require significant work."
"There could be improved automation for handling tasks in bulk or in an automated way."
"We'd like to see the solution expanded to include firewalls and endpoints."
"One area for improvement is the technical support for Purview. With all the other solutions from Microsoft we get really good technical support, but with Purview we had a compliance error and we couldn't find the solution. Purview would not point us to the correct solution, it just indicated the error. We had to troubleshoot it and find out what led to this error. We contacted technical support but it took them one week to identify the root cause of the error."
"We've had issues with data connectors for Teams."
"Integrating add-on licenses, which currently offer additional features at a cost, into the base product would be beneficial, especially for a charity organization to avoid incurring extra costs."
"When I tried to set up Microsoft Purview Compliance Manager for my organization to ensure people are not sending PII documents, especially payment cards, using keywords for flagging, it disrupted our services, so we had to deactivate it."
