    Hello Konstantin,


    Here is a quote from previous answer:

        "Let me tell you that, Jotform has a very powerful cloud of servers whose storage is encrypted and       provides security protection against malicious attacks like SQL injection and denial of service (DDOS) attacks."

    You can read more about the issue from here.


    Also here is a blog post written by the lead developer of Jotform.

    Hello OzanDost!
    Thank you for the reply.
    But what about the multiple submit requests on the the sign up form?
    Let consider such case -- I create a subscription form, place the code on my side
    and someone makes a hundred requests to subscribe via the form. Nowadays there are
    lots of bots that can attack forms on a website, so tons of emails will be sent from my form
    Do you provide ( maybe within form builder ) ant kind of protection from such threads ?
    Best regards,

    I recommend features and widget to fight spammers, spambots or multiple submissions to your form. Here's the list:

    1. CAPTCHA field -

    2. Google reCaptcha widget -

    3. Unique Submission feature -

    4. Unique Question feature -

    Please choose one or more to add it to your form. After that, if you have questions or need clarifications, don't hesitate to ask us. We're here to help.

    Thank you.
