A Secure Sockets Layer (SSL) is a protocol for securing communications on the Internet; ultimately, SSL provides the authentication and encryption of traffic between your browser and Internet servers. All Formstack Forms come enabled with 256-bit connect SSL to secure your form. Read more on security and privacy.
SSL on embedded forms
Formstack cannot enable SSL on your hosted website. If you embed the form on a website, your Formstack form will be secure; however, your web page won’t display this security unless your web host provider enables SSL on the page where the form is embedded.
If your site cannot have SSL enabled, provide a link that redirects to the form URL rather than embed the form to ensure your form functions correctly.
