AWS Network Firewall Icon

AWS Network Firewall is a managed service that acts as a security layer for your VPC (Virtual Private Cloud). It helps protect your network traffic by inspecting it against security rules you define. Think of it as a virtual firewall that sits between your VPC and the internet, letting you control which traffic is allowed in and out, based on criteria like source/destination IP addresses, ports, and protocols. This helps prevent unauthorized access to your resources and improves your network security posture.
