Antrea vs Aviatrix Zero Trust for Workloads

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 Zero Trust for Workloads applies runtime security policies to virtual machines, containers and serverless workloads. It governs traffic between workloads and between workloads and the internet, aiming to prevent lateral movement and data exfiltration. The product runs inline in existing cloud architectures; Aviatrix says deployment requires neither network redesign nor application disruption. Named cloud environments are AWS, Azure, Google Cloud Platform and Oracle Cloud Infrastructure. Identity-aware policies and SmartGroups use workload metadata, tags and namespaces to set least-privilege communication rules that follow workloads as they scale or move. Distributed inspection is described as stopping exploit traffic, malware and unauthorized communication in real time. Outbound controls include selective NAT, domain filtering and geographic filtering. Aviatrix says it encrypts workload-to-workload, north-south and cloud-to-cloud traffic at line rate without hardware or agents. CoPilot Telemetry provides visibility and compliance evidence, and the product describes alignment with HIPAA 2025, PCI DSS 4.0, NIS2 and DORA. Pricing is available on request.
