What is NetFoundry?
NetFoundry was founded by the inventors and maintainers of OpenZiti, an open-source zero-trust networking project, and sells a commercial platform built on it. The product delivers what NetFoundry calls "Identity-First Reachability" - cryptographic identity verification before any network path is established - to eliminate open inbound ports, VPNs, and firewall rule changes. Use cases include site-to-site connectivity, OT/IoT and API security, vulnerability cloaking for unpatched assets, and securing AI agent traffic.

Key capabilities
- Zero-trust overlay: Outbound-only, identity-verified connectivity with no open inbound ports.
- OpenZiti foundation: Built on the open-source project NetFoundry created and still maintains.
- Use-case coverage: Site-to-site networking, OT/IoT security, API security, and AI-agent traffic control.
Core areas are zero-trust network overlays, microsegmentation without network redesign, and securing machine-to-machine and AI-agent connectivity.
Shortlist NetFoundry if you want a commercially supported platform on top of the open-source OpenZiti project, rather than running OpenZiti yourself, and want to eliminate inbound-facing network attack surface rather than just segment it.
Because public pricing isn't listed, confirm current commercial terms directly, and clarify which capabilities require the paid NetFoundry platform versus what's available by self-hosting OpenZiti directly.
