Firewalls protect computers from hacker attacks and malicious programs when they are connected to the Internet or a local network. A good firewall provides protection for both inbound and outbound activity, and it can also be used as an additional layer of security for your antivirus solution to ensure that malware cannot reroute or hijack Internet traffic or bypass your anti-virus protection.

A good firewall will provide outbound filtering, which means that only certain programs can send data over the Internet. Many of the best firewalls do this by checking to see if programs are sending data to the Internet, and if so, whether it is encrypted or not. The software will then decide what to do with the data depending on your preferences and the threat level.

Some of the best firewalls will include features that help protect against specific types of threats, such as ransomware and phishing. Bitdefender Internet Security, for example, is a top choice for consumers looking for the best overall firewall protection available with advanced features such as web attack prevention, real-time data protection and anti-phishing tools.

Other firewalls will provide more advanced capabilities, such as the ability to perform Stateful Inspection of applications that are trying to connect to the Internet. This will evaluate each connection to look for the telltale signs of hacking, such as source routing and IP spoofing and can stop these connections from going through your firewall.
