Next-generation firewall is a more advanced version of the traditional firewall. It is 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.
A fully integrated next-generation firewall has more powerful features, including firewall, IPS, DLP, Antivirus, application control, VPN service, and URL Filtering, to fend off cyberattacks and emerging threats while increasing operational efficiencies.
