NGFWs use a more thorough inspection style, checking packet payloads and matching signatures for harmful activities such as exploitable attacks and malware.

Next-generation firewalls perform deeper inspection compared to stateful inspection performed by the first- and second-generation firewalls. The goal of next-generation firewalls is to include more layers of the OSI model, improving filtering of network traffic that is dependent on the packet contents. NGFWs include the typical functions of traditional firewalls such as packet filtering, network- and port-address translation (NAT), stateful inspection, and virtual private network (VPN) support. , and SSL decryption Next-generation firewall versus traditional firewall Other techniques might also be employed, such as TLS/SSL encrypted traffic inspection, website filtering, QoS/ bandwidth management, antivirus inspection, third-party identity management integration (i.e. Part of the third generation of firewall technologyĪ next-generation firewall ( NGFW) is a part of the third generation of firewall technology, combining a traditional firewall with other network device filtering functions, such as an application firewall using in-line deep packet inspection (DPI), an intrusion prevention system (IPS).
