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

"Knovos eZSuite has a nice interface and performance well. It has a good processing speed."
"Purview eDiscovery has made it significantly easier to handle rare litigation requests."
"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."
"Our legal team benefits from using Microsoft Purview eDiscovery."
"Tasks that took an entire day before we implemented Purview now take just 30 minutes."
"The most valuable feature of Microsoft Purview eDiscovery is the content search. We can use it to find the data we need by searching for keywords, phrases, or the sender or recipient. It helps us gather information from current employees or ones who have left the company."
"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."
"The most valuable features are automatic content logging tagging. Performing these tasks manually would be impossible. Since most of our data is already in Microsoft, it's convenient to run it through this tool."
"I think eDiscovery Premium has made dealing with data from Teams much more accessible than any other platform."
 

Cons

"The solution could improve by having better integration with different platforms. Additionally, the audio and video could have better support."
"I would suggest adding more platforms."
"I see two significant challenges with many of my clients. One is that there are some functionality gaps compared to specialized tools in the legal industry, like a legal hold tool or a document review tool. They have features that Purview eDiscovery lacks. Those gaps create a situation where I almost have to do things twice. I need to collect all my data in eDiscovery and ship it to another platform to complete the review."
"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."
"Microsoft Purview eDiscovery should be cheaper."
"The query language can be time-consuming to figure out if you don't know it initially."
"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."
"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."
"We find that many critical functions are available only to E5 license holders. It would be beneficial to have more options available for E3 customers. Enhanced Teams functionalities and better capture of text message data, both SMS and MMS, would also be improvements."
 

Pricing and Cost Advice

"We were using a trial license of the solution."
"The costs associated with E5 licensing are currently expensive for us, so we use the E3 license, which comes with fewer features and functionalities."
"Microsoft Purview eDiscovery comes as part of Microsoft 365 licenses."
"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."
"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."
