Cloudflare protects everything.

Cloudflare is more than DNS and a CDN for us. When logic needs to run before a request ever reaches the origin, we reach for Workers: lightweight functions that execute at the edge, close to the visitor. We use them for the jobs that belong in front of the application rather than inside it: redirect logic and URL rewrites, geolocation-based routing, bot filtering, A/B split assignment, and lightweight API proxying that keeps origin keys off the client. Because Workers run on Cloudflare's global network, that logic executes in milliseconds regardless of where the origin server lives, and it takes load off the application entirely. We keep the boundary clear, so edge logic stays edge logic and the application stays focused on what only it can do. For sites already sitting behind Cloudflare for security and caching, adding a Worker is a small step that removes a surprising amount of work from the origin.

Moving a live site behind Cloudflare is routine for us, and doing it without downtime is the whole skill. We start by importing the existing DNS records exactly, verifying every subdomain and mail record so nothing silently breaks when the nameservers change. We stage the caching and security rules in advance: cache levels tuned per content type, page rules for the paths that need special handling, SSL mode matched to the origin, and WAF and rate-limiting rules sized to the site's real traffic. Only once the configuration is validated do we move the nameservers, so the cutover is a switch rather than a scramble. After launch we watch the analytics to confirm cache hit rates and blocked-threat counts land where they should, then tighten rules from real data. The result is a site that stays up during traffic spikes, serves assets from the edge, and turns away malicious traffic before it costs origin resources.
