Product deployment protects assets but needs improvement in system support

I am doing maintenance for Microsoft Defender for Business, and I'm currently working with it. We don't need to use the latest version of Microsoft Defender for Business. We still use the latest virus definition file that Microsoft Defender for Business has automatically updated. We implement a basic update mechanism. Our compliance division manages how many servers and PCs we have and whether those servers have antivirus solutions. I am not certain about how Microsoft Defender for Business helps with AI-driven security strategies. I just use it normally and don't know if it uses AI technology. I rate Microsoft Defender for Business a six out of ten.

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.
