AWS Network Firewall is a managed service that makes it easy to deploy essential network protections for all of your Amazon Virtual Private Clouds (VPCs). The service can be setup with just a few clicks and scales automatically with your network traffic, so you don’t have to worry about deploying and managing any infrastructure. AWS Network Firewall’s flexible rules engine lets you define firewall rules that give you fine-grained control over network traffic, such as blocking outbound Server Message Block (SMB) requests to prevent the spread of malicious activity. You can also import rules you’ve already written in common open source rule formats as well as enable integrations with managed intelligence feeds sourced by AWS partners.
