Featured Reviews

Maria Greene - PeerSpot reviewer
A reliable solution with great searching capabilities and good tech support.
It depends on what you need. If you're a law firm and you have a lot of cases, then RelativityOne might be something to look into. If you're a small business and you're really focusing on small-level reviews, then there might be cheaper options for you. I think RelativityOne, because it is so powerful, can be very difficult to use and there's a lot that can go wrong if you don't know how to use it. In order to get the most out of your subscription, I would definitely recommend having someone who has had experience with it and knows how to work the program if you decide to make the investment. Alternatively, budget for some of the Relativity training classes. I would rate this solution as a ten out of ten.
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

"There are a lot of ways to QC your work and save your searches, and we had really good case support from the Relativity team."
"The initial setup was relatively straightforward."
"The ease of navigation from dock to dock, and that kind of usability, is quite helpful."
"It is easy for a beginner to learn to use Relativity."
"Caplets are a very good technical feature."
"I like Relativity's blackout feature, as well as the Case Dynamics function."
"kCura Relativity is easy to use, and it is reliable."
"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."
"Tasks that took an entire day before we implemented Purview now take just 30 minutes."
"Purview eDiscovery has made it significantly easier to handle rare litigation requests."
"I think eDiscovery Premium has made dealing with data from Teams much more accessible than any other platform."
"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 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 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."
 

Cons

"What I dislike about Relativity is that we have to go through the host in order to do productions and loads. It is not a do-it-yourself tool."
"The price per user could be improved. We'd like for it to be more affordable."
"The platform's integration of advanced AI features could further enhance its capabilities."
"I haven't seen anything on AI merging with Relativity."
"They require more built-in support for some third-party applications."
"There are a lot of bugs on the development side."
"I would definitely not recommended it unless you have someone who has had experience with it and knows how to work the program."
"We find that many critical functions are available only to E5 license holders."
"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."
"Microsoft Purview eDiscovery should be cheaper."
"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. 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."
"The query language can be time-consuming to figure out if you don't know it initially."
"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."
"I would suggest adding more platforms."
 

Pricing and Cost Advice

"It's worth the money."
"They are maintaining the per gigabyte pricing, and it's based on tiers of how much data you host with them."
"Users are typically charged a fee per user account and a separate fee based on the amount of data processed and hosted."
"The pricing is extremely complicated."
"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."
"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."
"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."
"With the full bundle, pricing is not a significant concern. As an M3, I find the Purview pricing of 1250 per user worthwhile."
