AWS Network Firewall is a firewall solution for Amazon Virtual Private Cloud (VPC) that provides pluggable support for third-party intrusion detection systems. It helps customers monitor and guard against unwanted traffic to and from their VPCs, with fine-grained visibility into potential attacks. Datadog's integration with AWS Network Firewall enables users to understand performance, discover trends in firewall traffic, quickly detect threats, and visualize metrics alongside other network infrastructure running in the VPC. The integration also makes it easy to spot unexpected surges or drops in traffic and provides an anomaly monitor to alert teams automatically if issues arise.
