What is AWS Network Firewall?

AWS Network Firewall is a managed service that allows you to deploy essential network protections for all your Amazon Virtual Private Clouds (VPCs). It provides features like stateful firewalling, intrusion detection and prevention (IDS/IPS), and web filtering to protect your network traffic. It's commonly used to centrally manage and enforce network security policies across multiple VPCs, inspect traffic based on custom rules, and block malicious activity.
