GlassWire

GlassWire monitors incoming and outgoing traffic to protect against intrusions. It’s among the most beginner-friendly and intuitive firewall programs I’ve seen. The app provides useful graphs that make it easy to tell what each process is doing. Once you’re in the app, you’ll see 5 tabs that highlight the following details:

OpenDNS

Note that OpenDNS Home works best alongside Windows’ built-in firewall. Since it’s not a complete firewall software, you’ll need another firewall to properly monitor incoming and outgoing traffic to help block network intrusions. All things considered, though, OpenDNS Home is a great free solution to improve online safety.

Norton

While the firewalls I’ve picked are good for basic safety, you should note that a premium antivirus with a built-in firewall is a better choice. For instance, Norton has a highly secure and customizable firewall that works besides its other features to ensure airtight protection. You can even try Norton without risk, as it’s backed by a 60-day money-back guarantee.

Intego

You can get Intego for as low as $19.99/year. However, Integos’ Mac Premium Bundle provides the best value, as it includes all the app’s key features at just $34.99/year. Also, you can try Intego without risk for 30-days, as it’s backed by a money-back guarantee. There’s also a 14-day trial that lets you try Intego’s firewall free on Macs.

BitDefender

Best of all, Bitdefender’s firewall is available in its free plan, meaning you don’t need a subscription to use it. Note, however, that getting a premium plan does increase overall security. Pricing for Bitdefender starts at just $29.99/year, but I found that its $49.99/year Total Security plan offers the best value.
