The discrimiNAT provides a solution for the inability to define hostnames or fully qualified domain names (FQDNs) within Google Cloud Firewall Rules and AWS Security Groups, enabling effective scalable egress filtering. By employing a Deep Packet Inspection engine, it monitors and blocks traffic without decryption, functioning as a high-availability NAT Instance at the egress point of your VPC network. We have designed the setup for this firewall to be incredibly user-friendly; you simply need to list the permitted destination FQDNs in the outbound rules of your applications, and the firewall manages everything else seamlessly. For a clearer understanding of its simplicity, check out the brief video demonstrations available. Our solution supports everything from complete multi-zone network setups that can be deployed with a single click, equipped with sensible defaults, to customizable instance deployments, allowing users to tailor their networking configurations as needed. Additionally, we offer a comprehensive collection of templates ready for immediate use in our CloudFormation library for AWS and as a Deployment Manager template for Google Cloud, ensuring that users can easily get started with powerful and efficient security measures.
