raspberry pi project for networks -- 2

I have a graduation project, which is cybersecurity, the idea is a piece of Raspberry Pi 4, which we will connect it to any type of router in the home and we it will be connected to a mobile app, the Raspberry should analyzes the internet data coming from the router and applies to it some of the commands that sent through the mobile application such as blocking the IP or a site and then the analyzed data should transfer to the cloud database. we will use open sources and APIs and NodeJS and Raspberry Pi 4. if you have any better idea to achieve this project it’s ok??
