Starting today, AWS Firewall Manager allows customers to define policies for centrally creating, deploying and managing Amazon Virtual Private Cloud Network Access Control List (NACL) rules for their VPC subnets across accounts in their AWS Organization. Additionally, NACL policies provide customers with visibility into policy adherence by reporting the compliance status for each policy.

With NACL policies, customers are able to implement baseline rules for protecting their subnets, such as pre-defined block-list rules, and automatically apply them across accounts. Customers also have the option to enforce NACL rules by enabling automatic remediation to revert unwanted changes and maintain a compliant network security posture.
