AD
Technical Solution Architect at liwa
Has enabled us to manage internal access securely but lacks accessible documentation for deeper integration
We haven't required any support, but overall, Microsoft support is good. Whenever we raise any concern, they are supporting us on time. Currently it is good. We are not a public-facing company; it is a retail company only, so that's why I don't think it is required. We don't have an e-commerce solution on Azure. For that, we are using a different stack for the e-commerce portal, so that is not in Azure. We are only using it for business applications, and I think L3 filtering in network security suffices for our problem currently. Regarding scalability for Azure Firewall, we don't need it here because the request to the application is internal. All are internal users. So there is not much request to get into the application, so scalability is not required for us in the current scenario.

Protects sensitive data across devices and helps address client compliance needs proactively
The reporting in Microsoft Purview Data Loss Prevention is a little easier than most Microsoft portals. I understand the licensing cost, especially if you're a Business Premium or in the SMB world, and a lot of clients run with a Business Premium. That comes with data loss prevention in a manual process, whereas E5 gives automation. Microsoft has said, 'Okay, here's your Microsoft 365 E5 compliance add-on that can go on the Business Premium.' So Business Premium users can get the data loss prevention features of E5, which is fantastic. That was the big point that they were missing, and I'm glad that they actually have an add-on now that makes it possible. So truly, I don't think there's a downside. Maybe more reporting, but that's it.
