Cloudflare is a global connectivity and security platform that provides content delivery, DDoS mitigation, DNS, Zero Trust networking, and edge compute services to accelerate and protect Internet properties. It operates a distributed edge network that caches and routes traffic, applies security controls (WAF, bot management, DDoS protection), and runs serverless code at the edge via Cloudflare Workers. Cloudflare’s suite reduces latency, simplifies network architecture, and provides unified observability and access controls for applications, remote users, and multi-cloud environments.
