Cloudflare runs a global network that sits in front of your website. It caches content on its CDN, blocks attacks, provides SSL and DNS, and filters traffic with a web application firewall.
Cloudflare also offers tools to build and deploy serverless apps. Workers lets you deploy serverless code across the globe, and Workers KV provides a secure, low-latency key-value store. Cloudflare’s storage products also let you create serverless SQL databases and store and retrieve objects. With Pages, you build full-stack applications that deploy to Cloudflare’s global network, and it supports popular frameworks including React, Hugo and statically exported Next.js sites. Pages Functions add server-side code without a dedicated server, and rollbacks let you revert to a previous production deployment.
For companies that need to secure staff rather than a website, Cloudflare sells a zero trust platform. Cloudflare says it gives every employee, contractor and AI agent identity-first access to internal applications, and that it replaces clunky, insecure VPNs. Its DNS and HTTP filtering shields branch offices and remote staff from phishing, malware and harmful sites.
