Slightly off-topic but does anyone have any suggestions for Little Snitch like application for Windows?

I've been using GlassWire: https://www.glasswire.com/

on windows I use WFC[1], which leverages the built-in firewall. Due to this though unlike LittleSnitch by the time you get a notification the connection has already been denied to the program, which can be an issue.
