The Trouble with Tor

The Tor Project offers an anonymous browsing service, which is important for individuals living in repressive regimes. However, it also provides value to online attackers, as 94% of requests from the Tor network are malicious. Cloudflare has not explicitly treated traffic from Tor differently but users of the Tor browser have been more likely to experience CAPTCHAs or other restrictions due to the high threat score associated with Tor exit nodes. The company is working on solutions that reduce the impact of CAPTCHAs on Tor users without compromising their anonymity and while keeping its customers safe.
