Instead of Antrea
Antrea alternatives
Antrea is a free, open-source Kubernetes networking and security project. It implements the Container Network Interface and Kubernetes NetworkPolicy, using Open vSwitch for pod networking and Kubernetes Service load balancing. VXLAN and Geneve overlays are available, as is operation without an overlay. Policy tiering, priorities, cluster-level policies, Node policies, multi-cluster federation, diagnostics, and Prometheus metrics extend its core networking role. Linux nodes can encrypt pod traffic with IPsec or WireGuard, but Windows nodes cannot. Antrea requires a Kubernetes cluster and the Open vSwitch kernel module on every node, while Azure support is best-effort.

Alternatives vary from Kubernetes CNIs and service meshes to workload access-control and micro-perimeter platforms. When switching, compare policy scope, data-plane choices, encryption, observability, supported platforms, and how directly each product handles pod networking. Also consider whether you need broader workload coverage, ingress or service-mesh controls, BGP routing, desktop virtualization, or enterprise segmentation instead of Antrea’s Kubernetes-focused model. Pricing ranges from free open-source projects to paid products with pricing on request.
