Zero Trust and Tunnels

Cloudflare can protect private apps without opening firewall ports.

📖 Key ideas

Cloudflare Tunnel (cloudflared) connects a server outward to Cloudflare, so no inbound ports are needed.
Access puts a login (Google, GitHub, email OTP) in front of internal apps.
Zero Trust means every request is verified, not trusted by network location.
WARP client secures staff devices' traffic.
Policies decide who can reach which app.

💡 Real-life example: Like a locked office with a guard at the lift: even staff show ID for every floor they visit.
