Cloudflare

Cloudflare is a global cloud services provider founded in 2009 by Matthew Prince, Lee Holloway, and Michelle Zatlyn, headquartered in San Francisco, operating one of the world's largest networks spanning over three hundred cities across more than one hundred countries, providing content delivery, DNS resolution, DDoS protection, web application firewall, serverless computing, and internet security services that protect and accelerate over forty million internet properties including sites for Reddit, Discord, Shopify, LinkedIn, and millions of small businesses. The content delivery network caches static and dynamic content across globally distributed edge servers, reducing latency and origin server load through intelligent routing, tiered caching, and image optimization, achieving average response time improvements of over fifty percent and bandwidth savings through compression and minification. The DNS resolution service provides the fastest authoritative DNS globally with sub-ten millisecond lookup times, supporting DNSSEC, CNAME flattening, geo-routing, and split-horizon DNS for different network views, freely available with unlimited queries on the free tier. The security services include DDoS mitigation capable of absorbing attacks exceeding one hundred terabits per second, web application firewall with managed rulesets and custom rules, bot management using machine learning and behavioral analysis, SSL and TLS encryption with free Universal SSL certificates, and rate limiting for API protection. The Workers serverless platform runs JavaScript, TypeScript, Rust, and Python at the edge with sub-millisecond cold starts. The R2 storage provides zero-egress S3-compatible object storage. The Pages platform enables static and full-stack deployment. The Zero Trust service replaces traditional VPNs. Designed for web developers, IT teams, and enterprises of all sizes.
