Zero-Trust Architecture (Cloudflare → VaultMesh)

Below is the high-level Zero-Trust flow integrating Cloudflare Edge, Tunnels, Access, DNS, and VaultMesh origins.

🔐 Identity & Access Flow

User resolves domain via Cloudflare DNS.
Edge enforces TLS, WAF, and bot checks.
Cloudflare Access challenges the user (SSO, MFA, posture).
If approved, Access forwards the request through a private Tunnel.
Origin service authenticates and emits VaultMesh receipts.
State and proof anchors propagate to ProofChain.

🚇 Cloudflare Tunnel Integration

cloudflared is the only transport path to origins.
Origins listen on localhost / private networks.
Each service has its own Access policy and Tunnel route.
Tunnel identity is tied to short-lived credentials.

🛡️ Security Controls at Each Layer

Edge: TLS enforcement, WAF rules, Bot Mode.
Access: Identity gating (email/group/MFA), device posture checks.
Tunnel: Mutual authentication, non-public network exposure.
Origin: Capability-scoped VaultMesh API.
VaultMesh: Receipt generation + Merkle-root integrity.

🔗 VaultMesh Integration Points

Each access event → creates a VaultMesh read-proof.
Each configuration change → DNS/WAF/Tunnel snapshot receipt.
Weekly proof anchors → ProofChain for immutability.

📦 Outputs

This architecture defines how

DNS routing
Edge security
Zero-Trust Access
Cloudflare Tunnels
VaultMesh integrity

all cooperate to produce a tamper-evident, private-by-default web infrastructure.
