NetFoundry Platform provides identity-first network connectivity based on the OpenZiti framework. The platform establishes connections between workloads, services, and networks using identity-based authentication and authorization before allowing any IP connectivity. The platform operates through a software-based network overlay that can be hosted by NetFoundry across 100+ points of presence or self-hosted. All connections use mutual TLS with X.509 certificates, and endpoints make outbound-only connections without requiring inbound firewall ports or VPN configurations. NetFoundry supports multiple deployment scenarios including IT/OT network segmentation, partner connectivity, customer onboarding, API protection, and internal microsegmentation. The platform provides visibility into connected traffic by identity and service rather than IP address. The architecture embeds zero trust connectivity directly into workloads and applications, enabling least-privilege access control based on specific identities and services. The platform denies all connections by default and requires explicit authorization for each connection. NetFoundry eliminates the need for site-to-site VPNs, ongoing firewall rule changes, and reduces attack surface exposure by making services unreachable from the internet until authentication and authorization complete.
