Hopr vs OVN-Kubernetes

Hopr provides Zero Trust access control for workloads and APIs using Cloud Native Automated Moving Target Defense. Its Workload Security Proxy is a lightweight proxy built on open-source Envoy and can be deployed with legacy virtual machines or container systems such as Kubernetes. Machine Alias ID gives each workload a frequently rotating identity credential. Hopr says its SEE protocol establishes a bidirectional, end-to-end encrypted channel for each session without a key exchange. Runtime Microsharding divides the application-layer attack surface into small, dynamic shards. Lane7 Blueprints are preconfigured Kubernetes networks that Hopr says can be deployed in under 30 minutes. Blueprint downloads are free, but use requires a Hopr license; the site offers a 30-day trial license. The Korvette-S WoSPs plan costs $35 per month per active WoSP and includes 1 billion sessions per WoSP and unlimited workloads. Enterprise Ultra includes unlimited sessions and workloads, with pricing available through sales. Hopr describes security leaders, DevOps teams, and platform engineers as its intended users. Its licensing is restricted in some countries by export regulations.

OVN-Kubernetes is a free, open-source networking solution and CNI-conformant plugin for Kubernetes, built on OVN and Open vSwitch. It handles pod IP allocation and interfaces, GENEVE overlays, Kubernetes Services, EndpointSlices, network policies, and IPv4/IPv6 dual-stack clusters. OVN ACLs enforce NetworkPolicy, AdminNetworkPolicy, and EgressFirewall rules; EgressIP, EgressService, and EgressQoS govern outbound traffic. Pods can join multiple networks, and the project also supports multicast, traffic shaping, BGP route advertisements, and SmartNIC or DPU offload. For KubeVirt, it provides persistent IPs during live migration; Hybrid Overlay enables mixed Windows and Linux networking. Deployment documentation covers Kind, Helm, DPU acceleration, kubeadm, and source builds. Requirements depend on OVN, nft, Multus, CNI, and Kubernetes versions; the master branch lists Kubernetes 1.33 or newer. Secondary User Defined Networks currently lack north-south traffic and core Kubernetes Services support. AdminNetworkPolicy APIs remain alpha and may change before stable v1.
