Onion Routingīeyond applying firewall filters to Tor traffic, Cloudflare users can improve the Tor user experience by enabling Onion Routing. Cloudflare updates its list of Tor exit node IP addresses every hour.

There's no geographical country associated with these IPs, but this approach lets Cloudflare customers override the default Cloudflare threat score to define the experience for their Tor visitors. The default level is Medium.Ĭloudflare assigns the two-letter code T1 for Tor. The choices for security range from Essentially Off to I'm Under Attack. Our basic protection level issues CAPTCHA-based challenges to visitors whose IP address has a high threat score, depending on the level chosen by the Cloudflare customer. Control Tor access via the Firewall app and enable Onion Routing in the Network app.ĭue to the behavior of some individuals using the Tor network (spammers, distributors of malware, attackers, etc.), the IP addresses of Tor exit nodes may earn a bad reputation, elevating their Cloudflare threat score.

Cloudflare does not automatically block visitors who use the Tor network.
