Cloudflare Network Firewall
Cloudflare Network Firewall is a firewall-as-a-service (FWaaS) offering for on-premises networks and WANs. No more bottlenecks — instead of backhauling traffic through firewall appliances, filter layer 3 and 4 traffic with the Cloudflare network, which has locations in over 330 cities throughout the world. This allows for secure and efficient network traffic management.
