Advanced threat protection secures diverse workloads with cost-effective deployment
If I need logs and don't have local storage bundled with Defender, I need to add workspace and log analytics, which is costly for storing logs of 2 GB, 5 GB, 10 GB. A default storage of 5 GB for logs should be included with Defender. There are limitations in whitelisting folders and files, and the whitelisting feature for Defender threat protection was deprecated. A straightforward feature for this should be added.
Roby Skariah - PeerSpot reviewer
Automation has given us consistent analytics and improved quality of insights into user activity
One of the valuable features of Purview is the ability to create a legal hold on a user's account within the compliance portal. That's pretty useful when it comes to any litigation or if you want to redeem the content within a mailbox, OneDrive, or a generic public SharePoint site. If you want to retain the user's data until the case is resolved, you can use the legal hold feature. Also, it's important that Purview can connect to iOS, Mac, and Android devices. With smartphone involvement, so many applications can now be accessed through them and it is important to apply Purview across operating systems and platforms. Purview's natively integrated compliance across Azure Dynamics and Office 365 is also significant because within Microsoft 365 there are multiple applications. Irrespective of whether it's Dynamics or Azure, it's very important that it has native support. The data connectivity should be efficient enough to support and secure their own platform's data. In addition, with varying regulations in different industries and matters, Purview lets you create rules and conditions based on industry standards around the world. That is important. Our company is in pharmaceuticals and the rules and conditions are different from other industries. It is important to be able to keep track of all these regulations and have a tool that is flexible enough to create the regulatory rules and conditions we need. And when it comes to data loss protection, Purview has features that can recognize patterns and detect any sort of data loss, where the data is being transferred from its platform to a different one. The default settings that come with it are pretty nice for identifying data transfer or data loss across the platform. It also comes with a lot of training materials, with use cases and examples, to help educate users and make them familiar with the tool.
