Secure Mobile AI Bridge

Zero-trust bridge connecting external mobile applications to on-premise infrastructure without opening any inbound ports. A containerised relay node deployed on edge infrastructure establishes an outbound-only encrypted tunnel to the private network. External clients authenticate through an edge proxy layer that validates requests before they ever reach the relay — two layers of authentication between the public internet and the internal network.

Edge authentication uses challenge-based token validation at the proxy layer. Only requests with valid credentials pass through to the relay container. The relay itself authenticates separately against the private network via its own encrypted tunnel. Traffic is encrypted end-to-end — the proxy cannot read request content, only validate authentication headers. No direct inbound connections to the target network exist at any point in the chain.

The relay container runs in an isolated environment with no persistent storage and minimal attack surface. It joins the private network mesh via an encrypted overlay, appearing as a trusted internal node to services behind it. Route configuration restricts which internal endpoints the relay can reach — it's not a general-purpose VPN, it's a scoped bridge to specific APIs.

Designed for mobile applications that need to reach private inference endpoints, internal APIs, and local services from outside the network. No firewall changes required on the private network side. No VPN client software on end devices. The mobile app talks to the edge proxy over standard HTTPS — the complexity of the secure relay chain is invisible to the client.
