Cloudflare, Inc.

Cloudflare Application Security provides WAF, DDoS protection, bot management, and API security through Cloudflare's global edge network spanning over 300 cities. It inspects and filters web traffic at the edge before it reaches origin servers, blocking application-layer attacks at scale. 

Cloudflare generates detailed security event logs covering WAF rule matches, DDoS mitigation actions, bot detection scores, rate limiting events, and managed challenge results. These logs enable security teams to analyse web application attack patterns, investigate incidents, and tune protection policies.
