The XSOS firewall
xSOS AI enhanced Firewall
Quite probably the most powerful internet tool ever devised, you could run scans on any website, see every ip address you connect to when opening that site, get detailed information about those addresses and create block lists of those addresses you did not want to connect too, like facebook, I had every known ip adress of facebook blocked and a host of others, giving me the cleanest, securest, and fastest surfing experience I ever had.
Unfortunately I had to do a complete OS reinstall a while back and can no longer use the software because the company vanished from the internet so it can't be re-activated.
I did not think it would last long however as it gave the user way to much control over the internet for the powers that be to let it exist.
