Enables us to guarantee that we followed the regulations
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. Purview's inclusion of critical regulations is essential. Lawyers will ask how we gathered information. With Purview, we can guarantee that we've followed the regulations. The visibility into what's happening and who has access is great for legal matters and saves us a lot of time.

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."
"Tasks that took an entire day before we implemented Purview 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."
"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."
"Purview eDiscovery has made it significantly easier to handle rare litigation requests."
"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 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 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."
"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."
 

Cons

"The solution could improve by having better integration with different platforms. Additionally, the audio and video could have better support."
"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."
"The sorting and filtering of the result data need improvement, and the interface for writing queries is not user-friendly for business users."
"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."
"Microsoft Purview eDiscovery should be cheaper."
"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 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."
 

Pricing and Cost Advice

"We were using a trial license of the solution."
"Microsoft Purview eDiscovery comes as part of Microsoft 365 licenses."
"With the full bundle, pricing is not a significant concern. 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. 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."
"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."
