Edge Security Acceleration (ESA) AI CAPTCHA blocks automated attacks with client-side HTML integration only. No server-side code is required.
Use cases
Websites and applications face automated attacks during user interactions such as registration, sending text messages, ticket booking, information queries, downloads, forum posting, and voting. Attacks like spam account creation, brute-force password attacks, and message flooding consume server resources and risk data breaches.
AI CAPTCHA is an intelligent verification service that distinguishes human users from automated programs by analyzing behavior, device fingerprints, and trajectory features. It offers multiple CAPTCHA types to balance security and user experience.
This feature is free of charge.
