No, you don't.


On other platforms, firewall software is needed to protect open communication ports against intrusion. Because iOS achieves a reduced attack surface by limiting listening ports and removing unnecessary network utilities such as telnet, shells, or a web server, no additional firewall software is needed on iOS devices.

Because you decided to have a problem that third-party advertising conveniently claims to resolve.


Advertising works, and gets some folks to install unnecessary, or sketchy, or rubbish, or privacy-invasive apps.


There’s a reason whole classes of apps get advertised heavily, as they’re far too often collecting your data.


One of the better-known Mac anti-malware packages was caught a while back reselling complete and personally-identified browser activities and online purchasing. They claim to not be doing that any more, of course.
