Network firewalls act as a secure outer perimeter to your network, preventing malicious content from accessing your systems. They are a crucial tool in any organization’s defensive strategy, due to their effectiveness and robust security features. Network firewalls examine every file and access request to your network, ensuring that only known and safe traffic is allowed to enter. This enables them to identify and prevent the vast majority of harmful traffic, unauthorized access, data breaches, and malware. 

Firewalls enable you to prevent threats from gaining entry in bulk, rather than having to spend valuable time addressing individual threats. They achieve this by filtering traffic based on pre-set policies and rules that define what should be allowed in, and what should be blocked. They carry out deep packet inspection on inbound and outbound traffic, giving you certainty that dangerous content cannot reach, or be distributed from, your network. Rather than using fixed notions of safe and unsafe traffic, firewalls can investigate individual instances to effectively stop malicious traffic, without increasing the rate of false positive.

In this article we’ve identified the top network firewall solutions and broken down their key features and use-cases. This should help you to understand more about each platform, thereby helping you to select the right one for your needs. Our reviews are based on features, market presence, technical capabilities, and user reviews.
