What is OpenZiti?
OpenZiti is an open-source zero-trust networking framework: an overlay network with native application SDKs (Go, C, Java, .NET, Swift, and more) so applications can establish outbound-only, mutually authenticated connections without exposing inbound ports or relying on a traditional VPN. NetFoundry, the company sponsoring the project, also sells a managed/hosted version built on the same code.

OpenZitiCybersecurityOpen-source zero-trust networking framework with embeddable SDKs
Key capabilities
- Overlay network: Outbound-only, mutually authenticated connections that eliminate open inbound ports.
- Application SDKs: Embed zero-trust connectivity directly into apps across multiple languages.
- Self-hosted control plane: Run your own controllers and routers, or use NetFoundry's managed option.
Embedding zero-trust connectivity in application code is a different operational model than a network appliance; validate your team can own the PKI and control-plane operations before committing.
