As someone else pointed out, if you want the ISP to provide you
with a completely "safe" network you will end up with something
like Minitel.

Note that the Minitel itself had many backdoors (not all of them being
blocked by servers) and has not been safe for years; the issue is
somehow comparable: The {app|minitel} has built-in vulnerabilities
{crummy code|hidden control codes}. Those of us that participated in the
early days of it still remember that when you wanted to get rid of
someone in a chat room all you had to do was to private a message
containing <esc>:f<ctrl-c><esc>9g
