Hello,
I am writing an iOS app which will filter web traffic for requests to malicious URLs according to our list. Instead of blocking them, the app will show a warning page, so users can choose to continue or stop. I intend this for the public, so I find the NE Content Filter not suitable for my app because it only works on supervised devices.
I have tried with a Safari extension but prefer a system-wide solution. Would it be appropriate to build a custom VPN Packet Tunnel without an external VPN server for filtering the requests? Also, I heard of the Screen Time API, and is it possible to customise the block page?
Thank you.
