Connecting to the Brave VPN will encrypt/mask any network data sent from your network. Using encryption to obscure your true IP and other internet data makes it harder for websites, ISPs or any other undesired parties to track or identify you. If you are interested in the type of encryption/protocols Brave VPN uses, please visit their Guardian's official FAQ for more information.

A firewall is software that runs on a network that is designed to block unauthorized access to your personal data or information while still allowing you to use the apps and visit websites normally on your device. There are different types of firewalls with respect to how they function but the end goal is the same: block or prevent unwanted connections from your device as you normally use your computer, mobile phone or tablet.
Other existing solutions utilize custom DNS resolvers and/or “hosts” files in order to block specific connections. Brave Firewall for iOS is unique in that it is a “true” firewall; in addition to having the ability to block DNS hostnames, it is capable of blocking connections to specific IPv4 or IPv6 addresses and ports, or block connections based on network packet content and/or metadata. Brave Firewall’s backend is similar to Intrusion Detection System software seen in the enterprise, such as Suricata and Snort.
