Handling Guidance

Usually allow
  • Log by default. Do not block Cloudflare globally unless you are protecting a specific origin endpoint and understand the proxy relationship.
  • Datacenter matches are network-origin signals, not bot identities. Use them with request paths, cadence, user-agent evidence, and customer rules.
  • Browser-looking traffic from cloud, hosting, VPS, CDN, transit, or automated infrastructure should be evaluated as infrastructure-origin traffic rather than automatically treated as a normal residential visitor.

Detection and Behavior

Operational guidance
  • Common traffic pattern: Cloudflare traffic often appears as server, VPS, cloud, CDN, transit, or automated infrastructure rather than a residential browser session.
  • Detection notes: Match by ASN AS13335. Combine network identity with user-agent, path, rate, country, and rule outcomes before enforcement.
  • Behavior thresholds: Flag when request volume, identical user-agent reuse, API/feed scraping, login probing, search abuse, or repeated non-human path traversal exceeds normal visitor behavior.
  • Human monitoring relevance: Useful for separating datacenter-origin requests from real human visitor traffic. Agency human monitoring should not classify hosting/cloud requests as normal residential humans without additional signals.
  • Recommended action: Log by default. Do not block Cloudflare globally unless you are protecting a specific origin endpoint and understand the proxy relationship.
  • Notes: Cloudflare is not a bot. It is an edge/CDN/security network. Treat source IPs carefully because visitors may appear behind Cloudflare.
