AWS Network Firewall is a fully managed service, making it easy to deploy network level protection for your Amazon Virtual Private Clouds or VPCs. There is no infrastructure to manage and can quickly be deployed and set up with just a few clicks within the AWS console. AWS Network Firewall provides the flexibility when defining firewall rules, allowing fine grain control over your network traffic, and increasing your ability to stop or block unwanted traffic. 

AWS Network Firewall also provides a way to import existing rules written in common, open source platforms, including third party intelligent integration feed source by AWS partners. We'll be talking about different deployment models available, but it is important to note that in order to essentially manage all AWS network firewalls, this service seamlessly works together with AWS Firewall Manager within an AWS organization.
