One breach can cost billions. One outage can cost the quarter. One bot army can drain your inventory before you've finished your coffee. Cloudflare blocks the attacks before they reach your code — every layer, every request, every day.
DDoS attacks don't ask permission. They show up in volume, at any layer, at any hour. Cloudflare's network absorbs them automatically — no rules to write, no pages to wake up to. Your origin keeps serving real users while the attack hits a wall it can't break.
Every request passes three checkpoints before reaching your origin: Managed Rules stop the known-bad payloads, Custom Rules enforce your own business logic, and Rate Limiting Rules stop the abuse that looks legitimate one request at a time. All edge-applied. All centrally managed. All without touching your application.
Modern apps don't ship HTML — they ship JSON. APIs are machine-readable, often undocumented, and the shortest path between an attacker and your data. API Shield discovers what you've got, validates what comes in, and scans what goes out.
One breach. One outage. One wave. The cost is real — and it shows up on the board's agenda. Cloudflare runs every layer of defense at the edge so the next attack stays a non-event, not a headline.
