A curated guide to 16 leading cloud network infrastructure vendors — eBPF-powered networking, service mesh, multi-cloud connectivity, hyperscaler networking services and distributed edge delivery.
Isovalent leads the eBPF-powered revolution in cloud native networking and security. As the creators and maintainers of Cilium, the open-source eBPF-based networking, observability, and security solution for Kubernetes, Isovalent provides the foundational technology layer for modern cloud-native infrastructure. Cilium has become the de facto standard for Kubernetes networking, adopted by major cloud providers and enterprises worldwide for its ability to deliver transparent encryption, deep network observability, and high-performance data plane processing powered by Linux eBPF.

Traefik provides automatic service discovery, load balancing, and TLS termination with native integration for container orchestration platforms.
VisitCisco Multicloud Defense, which began as Valtix, protects applications and services with a multi-cloud network security platform delivered as a service. It provides cloud-native firewall, network segmentation, and security policy automation across AWS, Azure, and GCP without requiring hardware appliances or complex configurations.
VisitNetskope One SD-WAN, which began as Infiot, delivers secure, optimized and intelligent access for remote workers, micro-branches and IoT as part of Netskope's converged networking and security platform.
VisitTigera is the company behind Project Calico, the widely used open-source networking and network security solution for Kubernetes, with commercial products for policy, observability and multi-cluster operations.
VisitSolo.io builds application networking products, including an Istio-based service mesh and a Kubernetes API gateway, for connecting and securing services across clusters and clouds.
VisitBuoyant created Linkerd, the CNCF-graduated, security-focused service mesh for Kubernetes, and offers enterprise support and tooling around it.
VisitAviatrix provides a software-only solution that enables quick and secure connections from data centers to the public cloud over any transport. Its distributed cloud firewall and advanced networking controls give enterprises centralized visibility and governance across multi-cloud environments including AWS, Azure, GCP, and Oracle Cloud.
VisitThe fastest and most secure way to deliver applications — deploy, connect, secure, and operate apps across multiple clouds and the edge. Now part of F5, the distributed cloud platform originally built by Volterra provides a unified SaaS layer for managing application services across multi-cloud and edge locations.

VisitMegaport provides on-demand, software-defined private connectivity between data centers, cloud providers and enterprises through network as a service.
VisitEquinix Fabric is a software-defined interconnection service that links customers directly to cloud providers, networks and partners across Equinix data centers worldwide.
VisitA network transit hub that connects Amazon VPCs and on-premises networks through a central gateway, simplifying routing and peering at scale.
VisitA Microsoft-managed networking service that brings branch connectivity, VPN, ExpressRoute and secure hubs together in a global transit architecture.
VisitA hub-and-spoke service for connecting VPC networks, on-premises sites and other clouds over Google's network from a single place.
VisitOracle's cloud networking services, including virtual cloud networks, FastConnect private connectivity, load balancing and network firewall.
VisitCloud network infrastructure is the set of networking services that connect workloads, users and sites across public clouds, data centers and the edge. It includes virtual networks, transit and interconnect services, cloud-native load balancing and proxies, and cloud-delivered network security.
Multi-cloud networking connects applications and networks across more than one cloud provider with consistent routing, security policy and visibility. Vendors such as Aviatrix, Alkira and F5 provide software layers for this, while interconnect providers like Megaport and Equinix supply private links between clouds.
Services such as AWS Transit Gateway, Azure Virtual WAN and Google Cloud Network Connectivity Center integrate tightly with one provider's cloud. Third-party vendors typically add a consistent control plane, security policy and visibility across several clouds and on-premises environments.
