In computing, a firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted internal network and untrusted outside network, such as the Internet. Firewalls are often categorized as either network firewalls or host-based firewalls. Network firewalls filter traffic between two or more networks and run on network hardware. Host-based firewalls run on host computers and control network traffic in and out of those machines.
The company's core products are a platform that includes advanced firewalls designed to provide network security, visibility, and granular control of network activity based on application, user, and content identification and cloud-based offerings that extend those firewalls to cover other aspects of security.
