I'm not involved in any way in developing pf. I'm first and foremost

a large-scale user of pf, I use pf for security, to manage threats both internal and external, and that helps to run large pieces of critical infrastructure in a redundant and scalable manner. PF is not just about "How do I make firewall", it is about learning techniques for manipulating your network traffic and understanding those techniques enough to make your life as a system and network admin a lot easier. It's impossible to put on one or more events, all the things you can do with PF, but for newcomer, it can get you up to speed on OpenBSD and PF .
