BotDetect CAPTCHA Generator Homepage
BotDetect™ CAPTCHA generator is a form security solution using Captcha challenges, that are easy for humans but hard for bots, to prevent automated page posting. Bots are kept from accessing protected website functionality using Captcha images specifically designed to be out of reach of computer vision and OCR technologies. BotDetect also provides an audio Captcha alternative to keep websites accessible to people with impaired vision, enabling you to make WCAG and Section 508 compliant websites.
BotDetect is unique among Captcha generators 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 generated 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.
Visual Studio 2015 & .NET 4.6 Ready
BotDetect ASP.NET CAPTCHA v3.0.16 supports the latest Microsoft Visual Studio 2015 and .NET 4.6 releases.
Full support for all Android & iOS devices
BotDetect 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.
It Does Not Spy
It helps that unlike recaptcha spyware joke, BotDetect doesn't operate under 'if we can doxx you then you are human' principles; and will not leave you to stare puzzled when your application starts getting rejected on national security grounds by the most of the world governments. If anybody ever tells you why in the first place. Be it on their own websites, or on the websites of their sensitive institutions and industries.
It is the Safe Bet for the US Gov Websites
It certainly doesn't hurt that BotDetect is the Section 508 compliant and actually legal on the US federal agencies' websites -- unlike the above mentioned spyware of dubious legality that is just lame-ducking there while awaiting for its Section 508 lawsuit by a disgruntled employee or a user to trash it away.
What is so different? It is simple. When you block cookies in your browser, or go into incognito mode so the spyware cannot spy any more, it reverts back to the old recaptcha. And a few things short of a miracle will help you make your application with the old recaptcha to satisfy this particular Section 508 requirement.
We are not familiar with the above mentioned legal case, nor its outcome, if there is any yet. It is very likely unrelated, and way more likely than not just a timing coincidence. But once bitten, twice shy. We guess once when you were hit with an accessibility suit of any kind -- you start paying attention. The following year the US Department of Homeland Security bought their first BotDetect license, and then some more since.
Hopefully, it will not be your application underpinning the spyware when such a kind of suit hits. While the sue-ball itself will be directed toward a particular federal agency, it will be your application -- not the spyware -- alleged to be the Section 508 non-compliant. You might have a hard time explaining it to your next potential customer.
It Works in China
Oh, we almost forgot to mention, BotDetect also works in China -- feel free to guess what 'captcha' doesn't :)
