Cloudflare is one of the world’s largest infrastructure and security companies. It operates as a Content Delivery Network (CDN) and a security layer between the user and the origin server. Founded in 2009, it has evolved into a comprehensive ecosystem including domain registration, DDoS protection, and edge computing (Serverless) solutions. It leads the “AI Gateway” field, enabling the monitoring and optimization of artificial intelligence traffic.
