Best Firewall Software

Researched and written by Lauren Worth

Firewalls are barriers used to secure networks from hackers, malware, and other attackers. Firewalls come in both hardware and software form, but all types provide fortified security between networks and outside threats. IT managers configure firewalls to specific system requirements, ensuring no data is vulnerable. Once implemented, they will monitor firewall tools to ensure security.

Smaller companies and personal computers will rarely require hardware firewalls, but large enterprise companies will use hardware firewalls within their own systems to limit access outside the company or between departments. The best firewall products will have significant overlap with network security software and web security software products, as they all aim to secure systems and information. Some products may come equipped with vulnerability management software tools to detect and defeat threats.

To qualify for inclusion in the Firewall category, a product must:

Assess and filter user access
Create barriers between networks and the internet
Alert administrators when unauthorized access is attempted
Outline and enforce security and authentication rules
Automate tasks associated with testing or monitoring
