Benefits of Using a Next Generation Firewall

Unlike most traditional firewalls, NGFWs also include a path through which future updates will be received. They can use whitelists or a signature-based IPS to distinguish between safe applications and unwanted ones, which are then identified using SSL decryption. These firewalls have extensive control and visibility of applications that it is able to identify using analysis and signature matching. The most obvious difference between the two is an NGFW’s ability to filter packets based on applications. There are also fundamental differences between the traditional firewall and next generation firewalls. Both firewall types should also be able to translate network and port addresses in order to map IPs. Like regular firewalls, NGFW use both static and dynamic packet filtering and VPN support to ensure that all connections between the network, internet, and firewall are valid and secure. Next Generation FirewallsĪs their name suggests, next generation firewalls are a more advanced version of the traditional firewall, and they offer the same benefits. A next generation firewall (NGFW) is, as Gartner defines it, a “deep-packet inspection firewall that moves beyond port/protocol inspection and blocking to add application-level inspection, intrusion prevention, and bringing intelligence from outside the firewall.” Traditional Firewalls vs.
