I like that it's free to use as long as you have basic protection enabled. The firewall is very easy to set up and has many options available. You can also setup rules which are helpful in blocking sites or apps from accessing certain websites or applications. Some of those features aren't always intuitive so they need some explaining before they're used correctly. That said, this product isn't too hard to figure out once you get started using it. If you want something simple but effective then look into this software. We've been able to block access to malicious sites/apps while still allowing necessary ones through the firewall. This makes managing security easier when compared to other products we were previously using.
