Do you offer a captcha function for a form that a create?

I only have 2 submission forms (both from JotForm) on my site. I have been getting hundreds of spam type emails mostly dumping within a few minutes. I've been told I need a Captcha function. Do you offer this on a form or is it added to my web site separately?

The Captcha field is available in the Form Builder.
