This is a tool that reads the access.log of Squid Proxy continuously.
It will check the URL part of each new logline for matching patterns specified
in a ACL file and records the match to a local logfile. The logfile with all
matches will be send as plain text email to a configurable destination.
Go and visit the OPNsense Documentation and setup a transparent proxy.

Download the CA Certificate and distribute it to your devices.
In most cases a "double click" on the File will trigger a import dialog
from your OS.
