AWS Firewall Manager now supports central monitoring of VPC routes for AWS Network Firewall

Starting today, AWS Firewall Manager allows customers to centrally monitor route configurations for AWS Network Firewall, and get alerts on routes non-compliant with their configuration. With this launch, customers can now monitor VPC routes to ensure traffic egressing through Internet Gateway (IGW) is inspected by the Network Firewall deployed by Firewall Manager in each VPC. Customers get alerted on route configurations that are non-compliant, such as, routes that bypass firewall inspection, or routes that lead to asymmetric traffic, and get suggestions to remediate the routes.
