Huge Demand for Next-Generation Firewall Industry


A Next Generation Firewall (NGFW) is part of the third generation of firewall technology, combining a traditional firewall with other filtering functions of network devices, such as an application firewall using the 'online deep packet inspection (DPI), an intrusion prevention system.

Other techniques can also be used, such as TLS / SSL encrypted traffic inspection, website filtering, QoS / bandwidth management, anti-virus inspection, and web integration. management of third-party identities (ie LDAP, RADIUS, Active Directory).

Some of the key players of Next-Generation Firewall Industry:

McAfee, Inc., Sophos Ltd., Cisco Systems, WatchGuard Technologies, Zscaler, Palo Alto Networks, Palo Alto Networks, Forcepoint, Fortinet, SonicWall, Kaspersky, Juniper Networks, Check Point Software, Barracuda Networks

NGFWs include the functions typical of traditional firewalls such as packet filtering, network and port address translation (NAT), stateful inspection, and virtual private network (VPN) support. The goal of next generation firewalls is to include more layers of the OSI model, thus improving the filtering of network traffic that depends on the content of the packet.

NGFWs perform a more in-depth inspection compared to the stateful inspection performed by first and second generation firewalls. NGFWs use a more in-depth inspection style, checking packet payloads and corresponding signatures for harmful activities such as exploitable attacks and malware.
