# Cloudflare Bot Management

Cloudflare's enterprise bot detection suite combining machine learning, browser fingerprinting, TLS fingerprinting, and JavaScript challenges.

Cloudflare Bot Management is Cloudflare's enterprise-tier bot detection product that operates at the CDN edge, before requests reach origin servers. It combines multiple detection signals: TLS and HTTP/2 fingerprint classification, JavaScript-based device fingerprinting (Canvas, WebGL, fonts), behavioural scoring (mouse movement, event timing), and IP reputation from Cloudflare's global network.

Cloudflare's challenge types escalate from invisible bot scores to Managed Challenge (which may silently pass or show a Turnstile) to explicit JS challenge pages. The free-tier Cloudflare WAF has a simpler ruleset; Bot Management (available from Business and Enterprise plans) uses the full ML-based detection stack that is significantly harder to bypass.

AlterLab handles standard Cloudflare protections in Tier 2 (TLS/HTTP2 compatibility) and Tier 3 (full browser rendering). Sites with Cloudflare Bot Management Enterprise may require Tier 4 or 5 depending on challenge aggressiveness. The `cloudflare_bypass: true` flag in the AlterLab request enables the appropriate escalation automatically.
