## AI overview

Fastly introduces a Challenge action for its DDoS Protection service, using Dynamic Challenges to reduce the risk that automated security rules block legitimate traffic during high-traffic events. The action can be enabled at the service or rule level, with responses tailored to request context, including background JavaScript challenges for people, CAPTCHAs for malicious bots, and API-to-API responses.
