Pros / This personal firewall software comes with a 100-percent virus protection guarantee.

Cons / Some features, such as its parental controls, don’t work with Mac or iOS devices.

 Verdict / Norton’s powerful firewall and exceptional malware detection work together to protect your devices from harmful threats, including ransomware, Trojans, hackers and bots.

Norton Security Premium includes a powerful personal firewall that monitors your network to ensure nothing suspicious breaks in to snoop around your computer, cause harm or steal information. The program works on Windows and Mac operating systems, plus it is compatible smartphones and tablets, so it can protect every device that connects to your home network. It works alongside your operating system’s firewall, providing an extra layer of protection. We think this program is especially good for families because it has extra tools to keep your children safe online.

We found that Norton Security is very good at monitoring computers, plus it did well in protection tests, making it one of the best firewall options. Also, it comes with a 100-percent virus protection guarantee, so if your computer gets infected, Norton will help clean your system for free.

During our in-house testing, we exposed Norton to over 200 live malware samples, including Trojans, rootkits, phishing schemes and malicious websites. It did a good job of blocking viruses that tried to download to our computer, and it warned us about dangerous sites before we visited them. We were especially impressed with Norton’s ability to block hidden threats that lurked on “broken” sites, such as those with suspended accounts and those that displayed 404 messages. Often on these sites, a virus download was still active, and Norton stopped it before it could attack our test computer.

Norton includes a scan that looks for vulnerable points in your system, such as out-of-date software, that serve as open doors for hackers and ransomware to enter through. This firewall software also lets you know if there are non-critical programs installed on your computer that you haven’t used in a while. Deleting these applications frees up storage space and limits the number of places malware can hide if it gets through. It also makes your computer run faster.

Norton Security Premium’s parental controls are very powerful and let you block inappropriate content by selecting filter categories. You can also use the software to track your child’s cell phone activity, including the messages they send. However, these tools are only available for Windows and Android – they don’t work on Mac computers or iOS mobile devices.

The program has other great security tools as well, including identity theft protection, a safe browser and a password manager. These features help shield personal information, such as bank account numbers, Social Security numbers and passwords, as you enter them online. Norton also comes with online backup storage, so it’s easy to restore your computer files and applications if your system crashes or you get a new computer.
