A next-generation firewall (NGFW) is a network security solution that combines traditional stateful firewalls with advanced software capabilities to protect enterprise networks from malicious threats.

NGFWs use deep packet inspection, application-level control, and other methods to target sophisticated cyberattacks.

Unlike standard firewalls, NGFWs are able to inspect incoming and outgoing traffic from applications such as HTTP (web browsers) or FTP (file transfers).

Monitoring this data in real time can detect attacks that wouldn’t be discovered through simple port filtering techniques used by regular firewalls.

This makes them an invaluable asset for enterprises looking for superior security coverage against advanced cyber threats that often bypass traditional protection tools.
