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.
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.

Quotes from Members

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

Pros

"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."
"I find Microsoft Defender very effective in vulnerability management and it provides good attack reduction, making it a next-generation protection solution."
"I believe it is best suited for cloud services and is unmatched by other cloud security solutions."
"The machine learning wasn't half bad. I really like that part. I thought it was novel. It pretty much automated it, once you trained the model."
"The ability to query everything that's in Microsoft and send links or add people, like managers, to review the documents is valuable. It's easy as I don't have to download and email anything. I just add them as a reviewer, and they can access it from there."
"I think eDiscovery Premium has made dealing with data from Teams much more accessible than any other platform."
"Microsoft Purview eDiscovery has saved me personally a lot of time because I can query it, and it touches everything we have as a full Microsoft shop."
"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."
"The return on investment is saving the equivalent of one or two full-time IT department employees and a few hours per week for legal staff."
"Purview eDiscovery has made it significantly easier to handle rare litigation requests."
"The tool has been beneficial. Some of our previous users left the organization without sharing the information they had at a personal level. This information was related to the organization, and they didn't disclose it. Thanks to the product, it's easy for me to search and find out what communication a specific user has done, whether it's from SharePoint or any other platform. With Microsoft Purview eDiscovery, we can easily retrieve and restore this data."
 

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."
"It has been one of the most solid tools I have worked with. However, Purview Data Loss Protection for remediating policy violations needs refinement, for example, in defining what constitutes a credit card because that is where I get the most false positives."
"I would suggest adding more platforms. Currently, it's compatible with OneDrive, Teams, SharePoint, and Exchange. Adding more features, as Microsoft continues to expand their cloud offerings, would be beneficial. Exploring options like Azure Files might be an avenue for improvement."
"The query language can be time-consuming to figure out if you don't know it initially. While there are options with dropdowns to select criteria, having a natural language feature would be beneficial. Copilot is expected to add such functionality in the future."
"Purview Data Loss Protection for remediating policy violations needs refinement, for example, in defining what constitutes a credit card because that is where I get the most false positives."
"The sorting and filtering of the result data need improvement, and the interface for writing queries is not user-friendly for business users."
"The query language can be time-consuming to figure out if you don't know it initially."
"The sorting and filtering of the result data need improvement, and the interface for writing queries is not user-friendly for business users. We still need all the backend stuff. We have to use Graph API to interface with everything and create custom interfaces on the front end to make it easier for the end users, which is costly. The reporting, sorting, and filtering capabilities that other products have aren't available natively in Purview."
"Purview eDiscovery works, but it's not entirely perfect. There were times when search results would get hung up or error codes would be presented and we'd have to contact Microsoft to get that sorted out."
 

Pricing and Cost Advice

Information not available
"The pricing and licensing with Microsoft can be complex, and licensing is known to be a challenge because it changes frequently. While the licensing for Purview is not as tricky as other Microsoft products, navigating licenses since the shift to E3 and E5 plans has been a task, as individual licenses must now be purchased separately."
"With the full bundle, pricing is not a significant concern. As an M3, I find the Purview pricing of 1250 per user worthwhile."
"The costs associated with E5 licensing are currently expensive for us, so we use the E3 license, which comes with fewer features and functionalities."
"In the positions that I've had through contracting over the years, I've heard talk of it being overpriced and underperforming compared to its competitors."
"Microsoft Purview eDiscovery comes as part of Microsoft 365 licenses."
