About Firewalls

A Firewall is a security system installed in a network that monitors both incoming and outgoing traffic. Based on a set of predefined security rules, the Firewall controls what goes in and what goes out. Usually, a Firewall acts as a barrier between a trusted internal network and untrusted network, a prime example being the Internet. There are two main types of Firewalls: network firewalls and host-based firewalls. A network security firewall is installed into the network hardware, and acts as a traffic filter between networks. Host-based firewalls run on host computers and directly control traffic coming in and out of those machines. The key network firewall market players are Cisco, Palo Alto Networks, Fortinet, and Check Point Software.

Firewall Growth Drivers

A Network Firewall is a fundamental component of the Network Cybersecurity Industry. Growth is driven by a rapidly changing Cybersecurity landscape and increased focus on Network Security, which includes unified threat management, firewalls, and intrusion detection and prevention technologies. An increasing portion of the market growth of firewalls comes from software-defined firewalls, rather than physical hardware firewalls. More and more companies are deploying their systems to the public and hybrid clouds. This naturally leads to increased spending on protection from cyberattacks, and with it the Firewall Market will certainly follow.
