A firewall is an app or a physical device that protects you when you're using a local computer network. It can block attempts to gain unauthorized access to the network, and it can block unauthorized communication by hidden and/or malicious software that's running on your device.
ZoneAlarm is easy to use and works alongside your antivirus and other security tools, including many other firewalls. Its Auto-Learn feature conforms to your computer use. After you've allowed your frequently used apps, ZoneAlarm mostly works in the background, only appearing when something changes, like when you install a new program that wants to connect to the Internet.
A snoop-free browsing experience can be difficult to achieve, but apps like the Tor Browser make it possible. The browser is a modified form of Firefox with built-in support for the Tor network. This is a network of encrypting relays between you and the Internet that makes it difficult for nosy people to intercept your private online communications or record your whereabouts. The Tor Browser works similarly to a VPN, but it's more decentralized, and it's free. The Android version is called Orfox and is used in combination with the Orbot app to connect to the Tor network. iOS doesn't have an official Tor option, but there are third-party Tor-aware browsers such as Art Fusion's VPN Browser.
