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.
While your home or workplace may be well-protected against digital intrusion, your local coffee shop may not have the best wireless security. Someone may also try to trick you into connecting to an unsafe public wireless network. In those scenarios, it's not a bad idea to have third-party firewall software running alongside or in place of Windows' built-in firewall.
Public Wi-Fi users may also want to consider a VPN, which will create a private encrypted tunnel between you and the website you're visiting. That makes it hard for other people on the public network to snoop on your activities. Check out our VPN buyer's guide. For the best experience, you will probably have to pay a subscription fee to access a VPN designed for personal use.
