Next-Gen Firewall (NGFW)
App-aware perimeter firewall with threat prevention.
9 options listedTypical cost: $15k-$150k/yrPROTECT (PR)
Overview
NGFWs combine stateful firewalling with deep packet inspection, application identification, and integrated IPS/anti-malware. They enforce segmentation and policy at network boundaries and increasingly at cloud edges. Sold as physical appliances, virtual machines, or cloud-delivered firewalls. Throughput tier and subscription bundles drive cost more than the box itself.
Baseline perimeter and segmentation control most environments still need.
Advantages
- Mature, consolidated L3-L7 control with one policy plane
- Palo Alto & Fortinet strong threat prevention
- Fortinet good price/performance
- pfSense/OPNsense free for small sites.
Trade-offs
- Appliance refresh cycles plus stacked threat subscriptions
- throughput-tier licensing gets pricey
- rule sprawl over time
- OSS options lack premium threat-intel feeds.
