Global Edge Ingress

Anycast DNS & Cloudflare Workers

Requests are routed to the nearest geographic edge node via Anycast BGP routing, terminating TLS in under 12ms before streaming through HTTP/3 to our core VPC network.

Zero-Trust Network Access

Mutual TLS (mTLS) & Ephemeral Keys

Inter-service communication is secured via Envoy service mesh sidecars enforcing strict cryptographic mTLS certificates rotated every 24 hours.
