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.

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 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 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."

"Our legal team benefits from using Microsoft Purview eDiscovery."

"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."

"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 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."

"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."

More Microsoft Purview eDiscovery pros

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

"The tool gives us the ability to trace the path of an incident."

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

"The product's valuable feature is its integration with other tools, such as risk management and risk assessment."

"It helps me in managing and using personal data while complying with the regulatory framework."

"The platform enhances the collaboration between data governance teams and other business units."

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

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

Cons

"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."

"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."

"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."

"I would suggest adding more platforms."

"The sorting and filtering of the result data need improvement, and the interface for writing queries is not user-friendly for business users."

"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."

"We find that many critical functions are available only to E5 license holders."

More Microsoft Purview eDiscovery cons

"Deployment is a big issue."

"The process management capability could be improved."

"The subject rights and concerns functionality needs to be improved."

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

"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."

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

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

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

Pricing and Cost Advice

"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."

"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."

"With the full bundle, pricing is not a significant concern. As an M3, I find the Purview pricing of 1250 per user worthwhile."

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

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

"The product is worth every penny."

"The solution is a low-cost option."
