AWS Network Firewall now supports flexible cost allocation via Transit Gateway

[AWS Network Firewall ](https://aws.amazon.com/network-firewall/)now supports flexible cost allocation through [AWS Transit Gateway](https://aws.amazon.com/transit-gateway/) native attachments, enabling you to automatically distribute data processing costs across different AWS accounts. Customers can create metering policies to apply data processing charges based on their organization's chargeback requirements instead of consolidating all expenses in the firewall owner account. This capability helps security and network teams better manage centralized firewall costs by distributing charges to application teams based on actual usage. Organizations can now maintain centralized security controls while automatically allocating inspection costs to the appropriate business units or application owners, eliminating the need for custom cost management solutions. Flexible cost allocation is available in all [AWS Commercial Regions](https://aws.amazon.com/about-aws/global-infrastructure/regional-product-services/) and Amazon China Regions where both AWS Network Firewall and Transit Gateway attachments are supported. There are no additional charges for using this attachment or flexible cost allocation beyond standard pricing of [AWS Network Firewall](https://aws.amazon.com/network-firewall/pricing/) and [AWS Transit Gateway](https://aws.amazon.com/transit-gateway/pricing/).
