How it works

Every AI Connection Starts With Identity

1AuthenticateThe AI user, the agent, and the machine each prove cryptographic identity
2AuthorizePolicy decides which MCP servers and tools that identity can reach
3ConnectAn end-to-end encrypted, outbound-only session opens to the approved resource
4Everyone ElseNo open ports, nothing to scan, nothing to reach

Use the human and machine identities you already have, or use ours.

NetFoundry reverses the traditional order: your AI stays invisible until it's authorized

One Platform, Every Connection

Secure Every Workload Connection the Same Way

The identity and policy model that secures your agents works across every connection in your environment, on the network you already have.

Trusted Where Failure Isn’t an Option

The organizations that can least afford downtime also can’t afford delay — and NetFoundry gives them both: production-grade security and connectivity that clears review instead of stalling in it.

“Our customers don’t even need to open a single inbound firewall port for us to remotely manage our software deployed on their networks. InfoSec reviews that historically took weeks became single-meeting events.”
John Wilson, CEO, TZ Limited
“NetFoundry provides the secure network foundation Rhapsody needs to support private, policy-based access across distributed healthcare environments, including applications, APIs, workloads, and emerging AI-enabled workflows.”
Kevin Day, CTO, Rhapsody
“We moved beyond the perimeter with NetFoundry. It delivers a strictly least-privileged access model that is incredibly easy to deploy, turning what used to be a tangle of firewall rules into a streamlined, visual command center.”
Viktor Szabó, Deputy CTO, Ominimo
Built in the Open

The Platform Runs on OpenZiti, and We Built It

NetFoundry created and maintains OpenZiti, the most widely deployed open source Zero Trust networking platform. The code carrying your traffic is auditable by anyone — no hidden behavior, no lock-in, no vendor you cannot verify. Run it yourself, or run it as a managed service with a global fabric and 24×7 Enterprise support behind it.
