## What Is NGFW? | Next-Generation Firewall
What Is NGFW? NGFW (Next-Generation Firewall) an advanced firewall that goes beyond traditional port and protocol inspection to include application-level inspection, intrusion prevention, and intelligence from outside the firewall.

## Why This Matters for Your Business
Traditional firewalls can't distinguish between legitimate web traffic and malware disguised as web traffic. NGFWs inspect the actual content of network packets, block application-layer attacks, and use threat intelligence feeds to stop emerging threats — essential as attacks become more sophisticated.
