Next-Generation Firewalls: What They Are and Why You Need One

Traditional firewalls filter by port and address. Next-generation firewalls understand applications, users and threats — a major leap in protection.

What makes them 'next-gen'

NGFWs add deep packet inspection, application awareness, intrusion prevention, and integrated threat intelligence. They can block malware, control specific apps and identify users, not just IPs.

Why it matters

Modern attacks hide inside allowed traffic. An NGFW inspects that traffic, stopping threats a basic firewall would wave through. It also simplifies policy by working in terms of apps and users.

Choosing one

Size the firewall to your throughput and feature needs. Al-Gazelle supplies Fortinet and other NGFWs and helps you deploy and tune them.
