BotDetect CAPTCHA Generator protects ASP.NET forms from automated spam submissions. Highly customizable, secure and accessible Captcha protection is available for ASP.NET WebForms, ASP.NET Web Pages and ASP.NET MVC web applications.
BotDetect is unique among Captcha solutions in offering many Captcha image and sound styles. While each of them is easily comprehensible to human users, randomly using multiple Captcha generation algorithms makes the Captcha challenge practically impossible to pass automatically. This approach to Captcha security is validated by the BotDetect track record: we have over 3000 paying customers and not one confirmed case of automated Captcha breaking by spammers.
BotDetect provides an audio Captcha alternative to keep ASP.NET web applications accessible to the blind and other people for whom reading the Captcha code could be a problem, enabling you to make WCAG and Section 508 compliant websites.
