A firewall is a device that monitors network traffic from the outside world to protect against cyber attacks and security threats.

These firewalls are referred to as Next Generation Firewalls (NGFWs) and are defined by their ability to address the more complex and ever-changing threats in the cyber security world. Using a combination of signatures on the hardware with the latest threat intelligence from cloud engine databases, a NGFW can stop unknown threats and prevent them from spreading to the network even if they have never been identified before. Upon deep packet inspection, if a profile cannot be matched against known threat or regular traffic types it will be 'sand-boxed' in the cloud until such a time it can be identified and classified. This type of enhanced firewall features help address 'zero-day' attacks and sophisticated ransomware and are highly recommended in protecting a network.
