Cloudflare bot solutions identify and mitigate automated traffic to protect your domain from bad bots.
Bot Management provides access to several new variables within the Firewall expression builder, as well as Workers cf objects, such as Bot Score, Verified Bot, and Serves Static Resource.
A bot score – cf.bot_management.score – is a score from 1 (automated) to 99 (likely human) that indicates how likely that request came from a bot.
These bot scores are generated by different detection engines, such as heuristics, machine learning, anomaly detection, JS detections, and others. Additionally, the __cf_bm cookie can be used to identify bots.
