NGFW

Next-Generation Firewall

Definition

NGFWs extend traditional stateful packet inspection with application-layer visibility, intrusion prevention, SSL/TLS inspection, and user identity awareness. Unlike legacy firewalls that only filter by port and IP, NGFWs can identify and control specific applications (e.g., block Dropbox but allow OneDrive) and enforce policies based on user identity from directory services.
