How secure is the submission data?

how can I secure the data of my customers?

Hello Franz ,

Data security for our users is a high priority for us. I can assure you that Jotform keeps your information safe. By default, all the forms/data are served across a protected 256 bit SSL (Secure Socket Layer) connection that uses a SHA256 Certificate. It is the industry standard of protection. You also have the option to enable Form Encryption in your forms, to add an extra layer of security to an already secured form. You can check our security page to learn more about other security features that Jotform offers.

Keep us updated and let us know if you need any more help.
