AWS Network Firewall
Deploy network firewall security across your VPCs
Automatically scale your network firewall to protect your managed infrastructure.
Protect your unique workloads with a flexible firewall engine that can define thousands of custom rules.
Centrally manage security policies across existing accounts and VPCs, and automatically enforce mandatory policies on new accounts.
How it works
With AWS Network Firewall, you can define firewall rules that provide fine-grained control over network traffic. Network Firewall works together with AWS Firewall Manager so you can build policies based on Network Firewall rules and then centrally apply those policies across your virtual private clouds (VPCs) and accounts.
