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

ROI

Sentiment score

Sentiment score
7.6
Microsoft Purview eDiscovery is praised for responsive support, despite some mixed experiences with wait times and outcomes.
They are sometimes responsive, however, often issues cannot be reproduced on their end, making it challenging.
The support we receive from Microsoft is declining, and for example, after taking advanced support, we have not received satisfactory answers.
My team raised multiple support tickets for the product, and we were able to get responses from Microsoft support team.
I would rate Microsoft Purview eDiscovery's customer service and technical support a ten.
 

Scalability Issues

Sentiment score
8.4
Microsoft Defender Vulnerability Management is praised for its high scalability and seamless integration, receiving consistently high user ratings.
Sentiment score
7.9
Microsoft Purview eDiscovery is scalable and efficient, seamlessly integrating with cloud infrastructures but lacks some search functions.
It is scalable; I evaluated the product and decided to use Defender on over 700 of our company servers.
It scales with us seamlessly.
With the E3 licensing, I would rate the scalability of Microsoft Purview eDiscovery as a six because it lacks certain critical search functionalities.
 

Stability Issues

Sentiment score
6.6
Microsoft Defender is rated highly stable with 99% availability, despite minor portal, compatibility, logging, and memory issues.
Sentiment score
8.6
Microsoft Purview eDiscovery is generally stable, with minor slowdowns, but users seek more transparency on performance issues.
There are compatibility issues occasionally arising with false positives when other security tools are not whitelisted in Microsoft Defender.
It is very resource-intensive, consuming a lot of memory and CPU.
I would rate the overall stability as an eight.
For us, it has been one hundred percent reliable.
Microsoft Purview eDiscovery is highly reliable.
 

Room For Improvement

Microsoft Defender needs improvements in accuracy, customization, integration, resource efficiency, macOS support, user-friendliness, and affordability.
Microsoft Purview eDiscovery needs faster, more efficient features, better integration, NLP for queries, and affordable pricing for users.
This scoring should be for specific industries as well. If I belong to the healthcare industry using Microsoft Defender Vulnerability Management, it should provide me with a risk score and show how I fare against the risk score of my industry.
A vulnerability I patch within 15 minutes takes 24 additional hours for an update.
The product is not stable; it often uses excessive memory and CPU, which makes it slow.
Adding more features, as Microsoft continues to expand their cloud offerings, would be beneficial.
Defining what constitutes a credit card because that is where I get the most false positives.
We find that many critical functions are available only to E5 license holders.
 

Setup Cost

Microsoft Defender offers varying pricing; complex licensing may incur additional costs, but security benefits can justify the investment.
Microsoft Purview eDiscovery pricing is complex, with E5 costly yet beneficial, while E3 is cheaper but limited.
Overall, every organization wishes for cheaper options, but we look at the security side as well, so we are good for now.
For non-partners, however, the cost could be seen as higher, between seven to ten.
The pricing is reasonable, and it's included in the whole Microsoft E5 bundle, so it's all-inclusive.
With CSP or MCE-style agreements with Microsoft, the process is streamlined since we have reps from both Microsoft and CDW working together.
As an M3, I find the Purview pricing of 1250 per user worthwhile.
The pricing and licensing with Microsoft can be complex, and licensing is known to be a challenge because it changes frequently.
 

Valuable Features

Microsoft Defender Vulnerability Management excels in integration, compliance, risk prioritization, and real-time assessments, enhancing security across diverse environments.
Microsoft Purview eDiscovery ensures efficient data retrieval with multi-platform integration, automation, compliance visibility, and adherence to global data privacy laws.
The main advantage of Microsoft Defender Vulnerability Management is that it can locate and prevent most threats even when the endpoints are not connected to the corporate network, as long as the internet is available.
The most valuable aspect is the kind of assessment results I get, and the recommendations provided in Microsoft products really help in taking care of the resources.
The integration with Sentinel has been one of the most valuable features for my organization.
The most valuable feature of Microsoft Purview eDiscovery is its ability to search across various platforms, including Exchange, SharePoint, Teams, and OneDrive.
Purview can connect to iOS, Mac, Android, and SaaS apps, which is critical for capturing SMS and MMS text message data.
Purview's inclusion of global regulations is critical because we're heavily regulated by FERC, Sarbanes-Oxley, and the SEC.

Featured Reviews

NaySan @ Suraj Verma - PeerSpot reviewer
Provides actionable vulnerability insights and recommendations with notable efficiency
They may need to improve the portal refresh rate for Microsoft Defender Vulnerability Management because it takes time for recommendations to disappear after mitigation; sometimes, it takes one week, when it should ideally take only one to two hours. Overall, everything is good with Microsoft Defender Vulnerability Management, but the portal refresh rate can take up to seven days in some cases and three or four days in others to reflect changes.
Frank Radeck - PeerSpot reviewer
Tasks that took an entire day before we implemented the solution now take just 30 minutes.
The most valuable feature of Microsoft Purview eDiscovery is its ability to search across various platforms, including Exchange, SharePoint, Teams, and OneDrive. It enables a streamlined, unified process for searching across these platforms. It is critical for Purview to be able to connect to iOS, Mac, and Android devices and data in other SaaS apps. From a support perspective, I can do things while I'm eating lunch or something else. It's more dynamic and responsive. I think everybody appreciates it. We're not tied to one device. Purview's multi-cloud capabilities are also essential for the same reasons. Keeping everything under one umbrella further increases the time savings. Purview accounts for critical regulations from around the world. This is crucial because we hold ourselves accountable to standards and need to align with them. Working at a law firm, we have clients who dictate to us what standards they expect. The visibility is excellent. As we move more things into the cloud, more opportunities exist to put everything under one umbrella.
