Cloudflare CSE Assignment - Edge Worker

Secure Remote Access with Zero Trust Architecture

The Problem

Your development team built an internal API running on a private network at 10.1.1.1. Works great in the office, but now your team works remotely. You need to give them access without punching holes in your firewall or managing VPN clients.

Challenge: Traditional solutions make you choose between security or convenience. VPNs are secure but frustrating. Port forwarding is convenient but dangerous.

The Solution

This demo solves that problem using Cloudflare's edge network. There's an API running on a private network accessible securely from anywhere. No VPN. No exposed IP. No compromise.

Try it: Visit /secure to authenticate. You'll see your identity, country flag from private R2 storage, and full API documentation fetched in real-time through a secure tunnel.

How It Works

Cloudflare Tunnel creates an outbound connection from the private network to Cloudflare's edge. Firewall stays locked down. No inbound rules. No exposed ports.

Zero Trust Access validates every request. Before you see anything, you authenticate with SSO. Cloudflare cryptographically verifies the JWT token. Every request. Every time.

Edge Worker orchestrates everything. Validates authentication, fetches country flags from private R2 storage, and securely proxies API requests through the tunnel. All in milliseconds.

CSE Step 7: Worker with identity info, R2 storage integration, JWT validation, and Workers VPC for private network access.

Key Benefits

Developers: Instant access with existing SSO. No VPN client. No network configs. Authenticate and you're in.

Security: Zero trust by default. Private infrastructure stays private. Every access logged. Compromised credentials? Revoke at IdP and access stops everywhere.

Operations: Setup once. No VPN servers to patch. No split-tunnel routing. No late-night connectivity issues.
