Compare 13 Cilium implementation partners delivering eBPF-based Kubernetes networking, Cilium Service Mesh as the sidecar-free alternative to Istio, Hubble for service-map observability and flow visibility, Tetragon for kernel-level runtime security and policy enforcement, the BGP and Egress Gateway capabilities that operationalise Cilium at the data-centre and multi-cluster edge, the migration patterns from kube-proxy, Calico, and Flannel to Cilium as the cluster-networking standard, Isovalent Enterprise for support and FIPS compliance, and the integration with the wider cloud-native security and observability stack that determines whether a Cilium programme delivers measurable operational advantage over the alternatives. Listings cover Isovalent partners, India-heritage SI Kubernetes factories, and the boutique cloud-native networking specialists. No partner pays for placement on this directory.
Cilium engagements split into three typical workstreams. CNI replacement and networking, where the partner replaces kube-proxy, Calico, or Flannel with Cilium as the primary CNI, configures the IPAM model against the cluster topology, designs the network policy framework with Kubernetes NetworkPolicy and Cilium NetworkPolicy CRDs, and engineers the BGP and Egress Gateway capabilities for multi-cluster and data-centre integration. Service Mesh and observability, where the partner deploys Cilium Service Mesh as the sidecar-free service-mesh layer, integrates Hubble for service-map and flow visibility, exports metrics into Prometheus and traces into Tempo or Jaeger, and engineers the mTLS and identity-based authorisation patterns. Runtime security with Tetragon, where the partner deploys Tetragon for kernel-level visibility and policy enforcement, integrates the security telemetry into the SIEM and SOC workflow, builds the runtime policy library against MITRE ATT&CK and the workload taxonomy, and operationalises the response patterns for runtime threat events.
Three procurement archetypes recur. Isovalent direct delivery (post-Cisco acquisition) leads on the most technically demanding programmes - large-scale CNI migrations, multi-cluster Egress Gateway topologies, FIPS-compliant deployments for regulated and government estates, and the deepest Tetragon engineering. Big Four and global SIs (Accenture, IBM, Red Hat) lead where Cilium sits inside a broader platform-engineering and zero-trust programme; their advantage is stakeholder reach across the operating model. India-heritage SIs (TCS, Infosys, Wipro, HCLTech) lead on factory delivery: large Kubernetes platform migrations to Cilium, sustained managed operations, and platform-team augmentation. Cloud-native boutiques (Container Solutions, Mesh Cloud, VSHN, nLogN, Giant Swarm) lead on technically complex networking work, the sovereign-cluster patterns, and the multi-cluster Egress topologies. Friction point: kube-proxy-to-Cilium migrations frequently slip when teams underestimate the network-policy translation work and the kernel-version dependencies, and Tetragon programmes that ship without disciplined policy curation generate alert volume that the SOC ultimately ignores.
