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.

Creates robust rules for communication and data security, boosting compliance measures
I was talking with some engineer from Microsoft about how we can audit our web page. They create or add to Microsoft Purview Communication Compliance that part, the Layer seven of the OSI model, to check the application and maintain a good practice of coding. I've tried the web page part, and it works great. However, monitoring and compliance for web applications could be improved.
