Next-Generation Firewall Overview

FortiGate Next-Generation Firewalls combine traditional firewall controls with advanced inspection, application control, intrusion prevention, malware protection, secure SD-WAN, VPN, and zero-trust access capabilities.

FortiGate appliances use Fortinet security processors and the FortiOS operating system to provide networking and security functions through a unified platform.

Key Capabilities (model- and licence-dependent):
Stateful firewall inspection Application visibility and control Intrusion prevention Antivirus and anti-malware protection Web and DNS filtering SSL and TLS inspection IPsec and SSL VPN Secure SD-WAN Zero-Trust Network Access Data loss prevention Inline malware prevention Centralised logging and reporting OT device and industrial protocol visibility
Feature availability depends on the FortiGate model, FortiOS version, licence, and FortiGuard service bundle selected.
FortiGate Next-Generation Firewalls protect users, data, and critical assets across hybrid IT and cloud environments. Powered by Fortinet security processors and FortiGuard AI-Powered Security Services, they deliver high-performance networking and real-time protection against advanced cyber threats.
