Fastly Bot Detection, part of Fastly Bot Management, detects and controls automated traffic to web applications and APIs, including AI crawlers, headless browsers and malicious bots. Detection combines server-side and client-side methods and analyses behavioural signals, protocol traits and client data over time rather than relying mainly on IP addresses or user-agent strings. According to Fastly, evaluation happens in real time at the edge, so traffic is assessed before it reaches the origin. Administrators can block, rate-limit or allow known bots and use dynamic challenges. It runs on Fastly's edge platform as a cloud service without changes to application code, and is also available as a managed service.
