What CAPTCHA Protection Can Do for Your Scenario

Login & Registration

In user login and registration scenarios, captchas can effectively resist automated malicious registrations (such as bulk registries using bots), while also effectively countering credential stuffing attacks from the source.

Flash Sales & Promotions

Bots claiming rewards prevent genuine users from accessing them, reducing promotion effectiveness and causing losses. CAPTCHA is ideal for flash sales, and coupons, blocking bots from coupon claims and bulk orders.

Likes & Posts

Malicious users exploit fake accounts to manipulate UGC communities, disrupting feedback and activities. CAPTCHA blocks bots, spam, and vote manipulation in forums, while addressing ad flooding and malicious posting.

Data Protection

Malicious crawlers steal website content and data, risking theft of core resources. CAPTCHA is suitable for content websites such as bulletin boards and forums, effectively defending against automated bots and crawlers stealing web data.
