BotDetect ASP.NET CAPTCHA
Lanapsoft BotDetect™ prevents automated submissions of ASP.NET forms using CAPTCHA images. The <BotDetect:Captcha> ASP.NET Custom Web Control generates and validates best-of-class Captcha images specifically designed to be out of reach of current computer vision and OCR technologies. The control provides a sound Captcha alternative as well, to keep ASP.NET web applications accessible to the blind and other people for whom reading the Captcha code could be a problem.
Why BotDetect ASP.NET 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.
BotDetect 3.0 Released
A new major BotDetect CAPTCHA release – v3.0 – is now available!
This approach to Captcha security is validated by the BotDetect track record: we have over 2000 paying customers and not one confirmed case of automated Captcha breaking.
The BotDetect ASP.NET CAPTCHA Control
This high-security Captcha protection can be added to your ASP.NET forms using drag-and-drop in the Visual Studio designer, or fully customized and randomized in codebehind and web configuration files. The control also comes with a number of C# and VB.NET code samples demonstrating how to integrate Captcha protection in various ASP.NET usage scenarios, and how to use the many available Captcha features.
