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.

Consent and cookies modules have enhanced the integration of data protection strategies despite challenges

There should be more customization options, as many things are restricted. This customization should suit individual needs, allowing for more UI customization, especially during consent collection. Also, improvements in data discovery and classification are needed, with the use of AI-oriented data discovery and more robust PDF file scanning capabilities. The scalability could be improved, particularly in detailed customization beyond the standard offering. Stability issues, like unexpected backend actions or data loss during updates, need to be addressed.

Quotes from Members

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

Pros

"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."

"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 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."

"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 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."

More Microsoft Purview eDiscovery pros

"The data flow analysis is especially valuable from a security perspective. It helps set a perimeter concerning security aspects."

"OneTrust DataGovernance has excellent on-premise data mapping and visualization capabilities."

"OneTrust allows seamless management of multiple geolocations at one time and offers workflow automation based on location-specific parameters."

"This allows anyone in the enterprise to easily find information about specific products or data elements."

"The product is easy to use, with excellent integration capabilities that, although they could be improved, are still better than other options."

"I recommend using a tool like OneTrust DataGovernance for managing regulated services, especially those handling personal information."

"This product makes it easy to manage personal data."

"One valuable aspect of the solution is its cloud-based nature. Users can just pay the fees and get started instantly."

More OneTrust DataGovernance pros

Cons

"The query language can be time-consuming to figure out if you don't know it initially."

"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."

"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."

"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."

"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."

"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."

More Microsoft Purview eDiscovery cons

"The platform could benefit from more competitive AI features, more user-friendly dashboards, and better automatic recognition or advanced templates."

"The integration with third-party products could be better."

"Deployment is a big issue."

"In OneTrust DataGovernance, there is room for improvement in creating customized email notifications in plain language and enhancing text editor features for form creation."

"Stability issues, like unexpected backend actions or data loss during updates, need to be addressed."

"The process management capability could be improved. It would be beneficial to have an authorization mechanism for users to process certain actions."

"The process management capability could be improved."

"The tool is an amalgam. It's a collection of loosely integrated pieces and parts that don't work well together. There is room for improvement there. My team reached out to the support team, and their experience was not satisfactory."

Pricing and Cost Advice

"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."

"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 product is worth every penny."

"The solution is a low-cost option."

"There is a licensing fee that we pay regularly."

"The product cost was reasonable due to a discount for NGOs."
