I work for a Large Government Agency.
My machines are on an internal network. Even though I have valid IPv4
addreses, my network is behind numerous firewalls that control all incoming,
outgoing, and even internal access.
...except the Web.
If I want to connect to a site over port 80 or 443, the network team
will not approve any firewall requests. I must use the designated "web
proxy", which provides my machine access to a list  of over 450 web
sites, including numerous that end with amazonaws.com
I can't have access to just the one web site I want. I can access all
of them, or I can access none of them.
Somehow, that qualifies as "network security".

 I went to download the list so that I could count its length. The
$LGA web site hosting the list has an SSL certificate that expired
this past Thursday.
