The Connectivity Cloud

Scaling a Better Internet: Security, Performance, and Reliability for Everyone.

01. Global Network & Infrastructure

Cloudflare runs one of the world’s largest networks, spanning **330+ cities** across more than 120 countries. This massive footprint allows them to handle an average of **57 million HTTP requests per second** while ensuring 95% of the world's population stays within 50ms of a data centre.

02. Enterprise-Grade Security

Cloudflare blocks an average of **247 billion threats** every single day. Their security suite includes Layer 7 DDoS protection, a world-class Web Application Firewall (WAF), and advanced Bot Management.

The Entropy Wall

For truly unpredictable encryption keys, Cloudflare famously uses a wall of **lava lamps** at their headquarters. The chaotic movement of the wax provides high-entropy data used for seeding the random number generators that secure approximately 20% of the web's traffic.
