Antrea vs Aviatrix Kubernetes Firewall

Antrea provides networking and security for Kubernetes workloads by implementing the Container Network Interface and Kubernetes NetworkPolicy. It uses Open vSwitch as its data plane, including for Kubernetes Service load balancing. Depending on infrastructure and use case, clusters can use VXLAN or Geneve overlays or run without an overlay. Antrea extends Kubernetes policy controls with tiers, rule priorities, cluster-level policies, and Node policies. It can federate clusters with a unified data plane, multi-cluster Services, and security posture. Diagnostics include command-line and UI tools for packet tracing, policy analysis, and flow inspection; metrics can be exported to Prometheus. Pod traffic encryption with IPsec or WireGuard is supported between Linux nodes, but not on Windows nodes. Deployment guides cover Amazon EKS, Azure AKS, and Google GKE, with GKE marked Alpha. The project requires a Kubernetes cluster and the Open vSwitch kernel module on every node, and its overview says it has been tested with Kubernetes 1.23 or later. Antrea is an open-source CNCF sandbox project under Apache License 2.0.

Aviatrix Kubernetes Firewall governs traffic entering, leaving, and moving between Kubernetes workloads across clusters and environments. It applies Zero Trust controls at the cloud network layer, outside Kubernetes clusters, so deployment does not require sidecars, agents, CNI replacement, or application changes. Policies can target pods, namespaces, services, and labels using Kubernetes-native identities. A centralized control plane manages policy across multicloud and multicluster environments, with automation options including Terraform, Kubernetes custom resource definitions, GitOps, and policies in Kubernetes manifests. Supported environments include AWS, Microsoft Azure, Google Cloud, and on-premises deployments, including EKS, AKS, and GKE. The product offers traffic visibility, observability, and anomaly detection, along with distributed firewalling, threat prevention, URL filtering, egress control, micro-segmentation, TLS decryption, DNS firewalling, and advanced NAT for overlapping address ranges. It can use a shared security model for containerized and legacy VM workloads. There is no free plan.
