A next-generation firewall (NGFW) is a type of firewall that is designed to protect a network by filtering traffic and blocking malicious content. It is a type of security measure that is often used in addition to traditional firewalls.
NGFWs are designed to protect against a variety of threats, including viruses, worms, and other malware. They can also block access to websites that are known to be malicious or that contain inappropriate content. NGFWs can also be used to control access to specific applications or services.
