If someone needs more insight - I am happy to help.
@valvaris , please a question:
Let's focus only at firewall functions.
But let's separate PRIVACY from SECURITY firewall functions.
And let's focus only at SECURITY firewall functions (or security benefits etc).
If I'm right, in terms of security, firewalls are almost useless.
I say "almost" because firewalls can block app, program, macro, cmd or powershell etc "OUT/IN" connections, avoiding/blocking tons of threats. But the real danger remains on browsing + webpages, which is the source of 90% of security problems. and where firewalls are almost useless.
Am I wrong?
