Whatever happened to the useful ones?

from here and here

One the plus side, I do get fewer useless alerts than I used to, but the useless ones still outnumber the useful ones by a wide margin. I don't even remember the last time I got a useful one. These days it's usually Windows telling me the firewall is disabled when it's perfectly fine.

Maybe I don't see useful alerts because the attacks never reach the computer with the firewall software in the first place. Maybe NAT-enabled routers were all most of us ever really needed.
