The goal of Fortinet's next-generation firewall (NGFW), the FortiGate, is to offer complete network protection for all network sizes. Here are some salient attributes and advantages:
A firewall is a type of network security device that uses pre-established security rules to monitor, filter, and regulate all incoming and outgoing network traffic. Building a wall between an untrusted external network and a trusted internal network is the main goal of a firewall.
Both software and hardware versions of firewalls are available. They function by examining data packets and using a set of rules to decide whether to allow or stop them. These rules allow organisations to allow or prohibit communication depending on a variety of parameters, including protocol type, source and destination IP addresses, and port numbers.
