Cloudflare Bot Management Technology Intelligence

What is Cloudflare Bot Management?

Cloudflare Bot Management is an enterprise-grade solution that uses machine learning and behavioral analysis to detect and mitigate malicious bot traffic while allowing legitimate bots and users through. It operates at Cloudflare's global edge network, providing protection without adding latency.

The service analyzes millions of requests per second across Cloudflare's network to build comprehensive bot signatures and behavioral models. It distinguishes between good bots (search engines, monitoring tools), bad bots (scrapers, credential stuffers), and humans using advanced fingerprinting and challenge mechanisms.

Detection of Cloudflare Bot Management indicates an enterprise investment in sophisticated bot protection, often used by high-traffic websites, e-commerce platforms, and financial services requiring advanced threat mitigation beyond standard WAF capabilities.

Cloudflare Bot Management Code Examples

Workers Bot Score Access

// Cloudflare Worker accessing bot score
export default {
  async fetch(request, env) {
    const botScore = request.cf.botManagement.score;
    const verifiedBot = request.cf.botManagement.verifiedBot;

    // Block likely bots (score < 30)
    if (botScore < 30 && !verifiedBot) {
      return new Response('Access Denied', { status: 403 });
    }

    // Challenge suspicious traffic (score 30-50)
    if (botScore < 50) {
      return new Response('Challenge Required', {
        status: 403,
        headers: { 'CF-Challenge': 'managed' }
      });
    }

    return fetch(request);
  }
}

Firewall Rule Configuration

# Block requests with low bot score except verified bots
(cf.bot_management.score lt 30) and not cf.bot_management.verified_bot

# Challenge suspicious automation
(cf.bot_management.ja3_hash eq "hash_value") and (cf.bot_management.score lt 50)

# Allow known good bots
cf.bot_management.verified_bot and cf.client.bot in {"googlebot" "bingbot"}
