# Cloudflare Bot Management
|
||||
|
||||
Enterprise-grade bot detection, protection, and mitigation using ML/heuristics, bot scores, JavaScript detections, and verified bot handling.
|
||||
|
||||
## Overview
|
||||
|
||||
Bot Management provides multi-tier protection:
|
||||
- **Free (Bot Fight Mode)**: Auto-blocks definite bots, no config
|
||||
- **Pro/Business (Super Bot Fight Mode)**: Configurable actions, static resource protection, analytics groupings
|
||||
- **Enterprise (Bot Management)**: Granular 1-99 scores, WAF integration, JA3/JA4 fingerprinting, Workers API, Advanced Analytics
|
||||
|
||||
## Quick Start
|
||||
|
||||
```txt
|
||||
# Dashboard: Security > Bots
|
||||
# Enterprise: Deploy rule template
|
||||
(cf.bot_management.score eq 1 and not cf.bot_management.verified_bot) → Block
|
||||
(cf.bot_management.score le 29 and not cf.bot_management.verified_bot) → Managed Challenge
|
||||
```
|
||||
|
||||
## What Do You Need?
|
||||
|
||||
```txt
|
||||
├─ Initial setup → configuration.md
|
||||
│ ├─ Free tier → "Bot Fight Mode"
|
||||
│ ├─ Pro/Business → "Super Bot Fight Mode"
|
||||
│ └─ Enterprise → "Bot Management for Enterprise"
|
||||
├─ Workers API integration → api.md
|
||||
├─ WAF rules → patterns.md
|
||||
├─ Debugging → gotchas.md
|
||||
└─ Analytics → api.md#bot-analytics
|
||||
```
|
||||
|
||||
## Reading Order
|
||||
|
||||
| Task | Files to Read |
|
||||
|------|---------------|
|
||||
| Enable bot protection | README → configuration.md |
|
||||
| Workers bot detection | README → api.md |
|
||||
| WAF rule templates | README → patterns.md |
|
||||
| Debug bot issues | gotchas.md |
|
||||
| Advanced analytics | api.md#bot-analytics |
|
||||
|
||||
## Core Concepts
|
||||
|
||||
**Bot Scores**: 1-99 (1 = definitely automated, 99 = definitely human). Threshold: <30 indicates bot traffic. Enterprise gets granular 1-99; Pro/Business get groupings only.
|
||||
|
||||
**Detection Engines**: Heuristics (known fingerprints, assigns score=1), ML (majority of detections, supervised learning on billions of requests), Anomaly Detection (optional, baseline traffic analysis), JavaScript Detections (headless browser detection).
|
||||
|
||||
**Verified Bots**: Allowlisted good bots (search engines, AI crawlers) verified via reverse DNS or Web Bot Auth. Access via `cf.bot_management.verified_bot` or `cf.verified_bot_category`.
|
||||
|
||||
## Platform Limits
|
||||
|
||||
| Plan | Bot Scores | JA3/JA4 | Custom Rules | Analytics Retention |
|
||||
|------|------------|---------|--------------|---------------------|
|
||||
| Free | No (auto-block only) | No | 5 | N/A (no analytics) |
|
||||
| Pro/Business | Groupings only | No | 20/100 | 30 days (72h at a time) |
|
||||
| Enterprise | 1-99 granular | Yes | 1,000+ | 30 days (1 week at a time) |
|
||||
|
||||
## Basic Patterns
|
||||
|
||||
```typescript
|
||||
// Workers: Check bot score
|
||||
export default {
|
||||
async fetch(request: Request): Promise<Response> {
|
||||
const botScore = request.cf?.botManagement?.score;
|
||||
if (botScore && botScore < 30 && !request.cf?.botManagement?.verifiedBot) {
|
||||
return new Response('Bot detected', { status: 403 });
|
||||
}
|
||||
return fetch(request);
|
||||
}
|
||||
};
|
||||
```
|
||||
|
||||
```txt
|
||||
# WAF: Block definite bots
|
||||
(cf.bot_management.score eq 1 and not cf.bot_management.verified_bot)
|
||||
|
||||
# WAF: Protect sensitive endpoints
|
||||
(cf.bot_management.score lt 50 and http.request.uri.path in {"/login" "/checkout"} and not cf.bot_management.verified_bot)
|
||||
```
