BotDetect CAPTCHA Generator protects ASP.NET/Core forms from spam. The Captcha protection is available on .NET/Core for jQuery, Angular & React frontends and ASP.NET MVCCore, MVC1-5, WebForms & WebPages backends. It works in China; doesn't stalk; nor does it slurp your form-data -- think: GDPR & LGPD!
BotDetect uses many different image and sound algorithms for the generation of Captcha codes. While each Captcha algorithm is easily comprehensible to human users, generating Captcha codes by random algorithm makes the Captcha challenge extremely difficult to pass automatically.
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.
BotDetect is a self-hosted .NET Captcha Component -- no 3rd-party servers are involved in the generation, displaying, and validation of Captcha challenges.
Therefore, BotDetect neither identify nor stalk your users and visitors -- nor does it slurp logins, passwords, and other data they fill in your forms.
This allows for the GDPR, LGPD, and CCPA compliant sites -- and also does miracles for the forms on any of the national security-sensitive ones.

What nuget to use?

* Use THIS nuget for ASP.NET applications running on the legacy .NET (non-Core) Frameworks
* Use THIS nuget for ASP.NET Core applications running on the .NET Core Frameworks
However, there is one special case that required the separate nuget.
* Use our NEW helper nuget INSTEAD OF this one for the special case of ASP.NET Core applications running on the legacy .NET (non-Core) Frameworks.
The new helper nuget name is CAPTCHA.asp.net.core.on.legacy.net.frameworks and it is available at CAPTCHA.asp.net.core.on.legacy.net.frameworks
