Featured Reviews

Brian Grossman - PeerSpot reviewer
Director of Sales at Opveon Litigation Services LLC
A powerful tool for litigation support services, such as production processing to meet client requirements
LAW PreDiscovery can simplify its interface and offer a cloud-accessible version tailored to customers. We often use other cloud-based document review software alongside LAW PreDiscovery to meet specific needs. This interchangeability allows us to handle specialized export requests more effectively. There also needs to be a more straightforward process for upgrading licenses without contacting support.

Senior System Engineer at a sports company with 5,001-10,000 employees
Has made it significantly easier to handle rare litigation requests
The speed of it is valuable. I am able to search even 10,000 mailboxes for specific content. It helps search and accommodate the often limited information provided by users regarding what they need. It provides a solid starting point, and then we are able to refine the data from there. That has been very helpful because we do not always get enough information from our users to know what to look for. For example, a user is missing an email from x date but does not know anything else. In such a case, I give them a list of emails to look at so that they can tell me what they are missing. It is not a lack of the tool. It is more of a lack of the user providing info.

Quotes from Members

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

Pros

"I've found the ability to customize exports and indexing in LAW PreDiscovery to be the most valuable feature. It allows us to meet our customers' specific needs effectively."
"The sourcing and the detailed background checklist are the most valuable features of this solution."
"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 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 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."
"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 eDiscovery has made it significantly easier to handle rare litigation requests."
"The speed of it is valuable. I am able to search even 10,000 mailboxes for specific content. It helps search and accommodate the often limited information provided by users regarding what they need."
"Tasks that took an entire day before we implemented Purview now take just 30 minutes."
"I think eDiscovery Premium has made dealing with data from Teams much more accessible than any other platform."
 

Cons

"LAW PreDiscovery can simplify its interface and offer a cloud-accessible versiontailored to customers. We often use other cloud-based document review software alongside LAW PreDiscovery to meet specific needs. This interchangeability allows us to handle specialized export requests more effectively. There also needs to be a more straightforward process for upgrading licenses without contacting support."
"If these details, photos, dates of birth, and so on are not possible to include, I believe it would be much more efficient if multiple people could log in using the same email address, as we can in some other programs."
"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."
"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."
"I would suggest adding more platforms."
"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."
"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 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."
"The sorting and filtering of the result data need improvement, and the interface for writing queries is not user-friendly for business users."
"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

"LAW PreDiscovery licenses are pretty costly and are on a yearly subscription basis. Before committing to LAW, it's crucial to calculate and ensure that you'll see a return on investment."
"With the full bundle, pricing is not a significant concern. As an M3, I find the Purview pricing of 1250 per user worthwhile."
"Microsoft Purview eDiscovery comes as part of Microsoft 365 licenses."
"The costs associated with E5 licensing are currently expensive for us, so we use the E3 license, which comes with fewer features and functionalities."
"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."
"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."
