Automatic Captcha Protection!

Today, we’re excited to announce that we’ve implemented a new smart captcha system to protect the data integrity of all forms powered by Wufoo. A captcha is a test used on a web site to make sure that the data being submitted to a form is actually coming from a human and not an automated bot or script. They’re used to prevent abuse and data contamination.

With Captcha!

While a number of our users have requested this feature from us for awhile, we’ve been hesitant because a number of studies have shown that when a captcha is used on a form, it severely impacts the conversion rate. This is because it also slows down and turns away legitimate users, who often get frustrated by the extra test.

In an effort to balance the needs of our users who want to insure the integrity of their data with our desire to promote best practices for high converting forms, we implemented a smart captcha system in Wufoo that tries to automatically detect abusive behavior and only show a captcha test in those situations. Here’s a ( we made to show off the feature in action.

Captcha Setting in Form Builder

We’re also very proud to be using [reCaptcha]( to help power our new anti-bot system. They’re used by web sites all over the world and we think it’s great that we’ll also be able to help digitize texts that are being scanned and stored in digital format for preservation and accessibility.

By default, all forms in Wufoo are set to automatic protection, but you can also set the captcha system to always show or never show the captcha on your form as well. You can find this feature’s options under the form settings tab when you edit your form.


  • Fantastic. Great work!

  • Everyone needs a hug.

    I really like the smart compromise achieved in not ‘forcing’ this on everyone yet providing security from bot attacks.

    I like that you have given options to the users rather than ‘forcing’ captcha on every form.

    Kudos and monkeys to you.

    I don’t know what this means yet but if it is going to increase security and integrity of our web forms then I applaud you!

  • Captcha & other abuse prevention technologies are good for their intended purpose but it requires an extra step from an otherwise straightforward process. Most times i find the extra step cumbersome – i make a mistake, i have to type several characters again.

    In this regard, I appreciate the solution that wufoo is implementing in that it only appears if there is evidence the form is being abused. Thanks wufoo and more power!!!

    Thanks for adding this feature!

  • Sounds good. So, I don’t have to do anything to my forms, right? They will automatically be protected? Our company e-mail domain has recently been blacklisted by some of the big security programs…and it’s possible (though not yet confirmed) that the source was traced back to our forms. So, the sooner this is implemented, the better. Thanks again.

  • Yes, forms are automatically protected.
