BotDetect ASP Classic CAPTCHA Generator
BotDetect™ prevents automated submissions of Classic ASP forms using CAPTCHA images. The
BotDetect.Captcha COM component generates best-of-class Captcha images specifically designed to be out of reach of current computer vision and OCR technologies, while the wrapper ASP Captcha library manages user input validation and other web tasks. The component provides an audio Captcha alternative as well, to keep ASP websites 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.
Why BotDetect ASP Classic CAPTCHA?
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 2500 paying customers and not one confirmed case of automated Captcha breaking by spammers.
Visual Studio 2013 & .NET 4.5.1 Supported

Full support for all Android & iOS devices
BotDetect ASP.NET CAPTCHA v3.0.13 audio now works on Android and iOS devices. Unlike other Captchas, sounds are played directly on the form page, without opening the media player app.
The BotDetect ASP CAPTCHA Component
This high-security Captcha protection can be added to your ASP forms with a single line (
<!-- #include file="BotDetect.asp" -->), and fully customized and randomized by editing the
BotDetect\CaptchaConfig.asp file. The control also comes with a number of ASP/VbScript code samples demonstrating how to integrate Captcha protection in various ASP usage scenarios, and how to use the many available Captcha features.
