Microsoft Purview Data Loss Prevention has absolutely helped improve my organization's ability to manage data because we use M365 for the majority of our knowledge worker storage, and that's where people's data lives.

My favorite feature about Microsoft Purview Data Loss Prevention is actually quite simple: there's a handful of things that you do, you create a new batch, it'll give you a unique ID, you copy that unique ID, it's a URL, and then you can put that into a script that we wrote so we just paste that in our script and then it uses that URL to upload all of those mailboxes, and then we can use that to import.

The stability and reliability of Microsoft Purview Data Loss Prevention is great. Besides the weird timeframe where it takes a couple hours for a rule to sync and 24 hours to appear for someone, I don't really have an issue.

Director, IT Infrastructure at a university with 1,001-5,000 employees

Improving Microsoft Purview Data Loss Prevention would involve recognizing that the whole AI path we are all on is going to help, given the massive amount of data we handle; even if there are true positives, implementing a degree of severity ranking is essential.

Perhaps with the advent of AI, it can be enhanced, especially with organizations that handle and process huge amounts of data.

I would assess the stability and reliability of Microsoft Purview Data Loss Prevention as being flaky at times, where eDiscovery sometimes takes forever or doesn't bring the results we expect.

The major challenge we had was overreach. When our initial design inception blocked more data than we expected, we had a lot of help desk related issues that we did not see in testing.
Iohann Gessenay - PeerSpot reviewer

Nov 19, 2025
I would say the improvement of Microsoft Purview Data Loss Prevention could be in the propagation of policies, as if you create a policy, it may take up to 48 hours to propagate to devices, and this might take a little bit longer than ideal.

I see that there's a lot of content in Microsoft Purview Data Loss Prevention, and when I click on it and look around, I wonder what certain features do, but there's not enough documentation and explanation.

To improve Microsoft Purview Data Loss Prevention, I think it would be helpful if we could make bulk labeling easier, as it is a little cumbersome at the moment.
