Provides data protection across platforms and connects to different devices
The rollout of Microsoft Purview Data Lifecycle Management is not yet complete. The goal of this implementation is to mitigate the risk of oversharing, particularly in anticipation of the broader adoption of Copilot. Purview's ability to connect to iOS, Mac, and Android devices, as well as data in other SaaS applications, is crucial. As a university with a bring-your-own-device policy, we cannot control the devices used by our diverse population of students and faculty. Therefore, an inclusive ecosystem that seamlessly integrates with various devices is essential, as we cannot enforce restrictions on specific devices or mandate particular technologies due to the open nature of our system. It is critical that Purview provides data protection across diverse cloud and platform environments, including AWS and GCP. Historically, our primary platform has been AWS, but we are increasingly expanding into Microsoft Azure. Therefore, I anticipate a future where we utilize both platforms extensively, making comprehensive data protection essential. Purview's design incorporates critical global regulations, ensuring compliance for university researchers and the institution itself with government and various regulatory requirements. Purview enhances visibility across our data estate. The new AI-powered data security features, especially the oversharing report, promise to be invaluable by providing insights into potentially overshared files and sites. This automation eliminates the need for custom scripts and manual data mining, previously necessary for identifying such issues, and ultimately saves significant development time. Purview saves time by eliminating the need for manual scripts, which can take days to run due to the volume of people and sites involved. Instead of running scripts multiple times or waiting hours for completion, Purview's built-in functionality provides immediate access to reports, streamlining the entire process.

Provides peace of mind and expands well but needs a better interface
It's a hosted solution. I'm not sure which version of the solution Im on at this time. I would advise others to research all the options out there and see what the best fit is. We started this mailbox continuity project before we moved to Office 365. And now that we've moved to Office 365, we kind of don't need this piece of technology in the same way that we used to need it when we had an on-prem exchange. Therefore, make sure that you actually need it and then research to find the best options. Overall, I would rate the solution seven out of ten.

Quotes from Members

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

Pros

"The UI is the most valuable feature."
"Purview's built-in functionality provides immediate access to reports, streamlining the entire process."
"The automatic data labeling is compelling, and we are investigating its use."
"The system is stable; I haven't encountered any worldwide stability issues unlike other office products."
"The security is pretty good, and that's why we're going to upgrade to an even more advanced package. We used it when we had a power issue, and it works. It has been pretty reliable, and the support has been quite good."
"It has all the features required for distribution, such as the ability to mail."
"Mimecast has some good support services in place."
"We're now certain business-critical mail is perfectly protected in multiple ways."
"The most valuable feature of Mimecast Mailbox Continuity is real-time alerts."
"The Large File Send feature comes in handy when you have to send fairly large attachments."
 

Cons

"Microsoft Purview Data Lifecycle Management can be challenging to implement due to its complexity and dense documentation, making it difficult to get started."
"Microsoft's Purview Data Lifecycle Management preview features can be unreliable, hindering their usefulness."
"Microsoft Purview Data Lifecycle Management can be challenging to implement due to its complexity and dense documentation, making it difficult to get started."
"The time it takes to scan is one issue; when we raise high-volume issues and tickets related to scanning failures, it relates to permission errors, which are technical challenges."
"Technical support has been slower than it was in the past, likely due to the pandemic."
"The solution is expensive in comparison to similar solutions."
"The interface and the documentation could be improved. They can also include some more training resources and content like video. While setting things up, I had to search for the information quite a bit. It took me time to find the correct way to do something. The information is there, but it is sort of all over the place. They can create a better help knowledge base or help portal. It retains your email for 45 days. They can maybe increase this duration."
"The price of the solution is expensive. It can improve by reducing the price."
"The interface isn't the best. How everything works on the back end is confusing."
 

Pricing and Cost Advice

"The service operates on a pay-as-you-go basis, charging an extra one cent per field of metadata scanned in our data."
"The price of Mimecast Mailbox Continuity is expensive."
"Its price is in the middle range. It is a structured licensing model where there are various components that you can add or choose to add or not."
