Cloudflare CAPTCHAs are challenge-response tests used to differentiate between legitimate human users and automated bots. They're employed by websites using Cloudflare's services to protect against malicious traffic like DDoS attacks, spam, and credential stuffing. They verify a user isn't a bot before granting access to a website.
