JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
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.
So, we do provide a high security standard through out our hosting provider's servers for data storage. Forms links and embed codes are SSL by default. All of our SSL certificates support high-grade 256-bit encryption.
Also, you can encrypt your forms, enabling Encryption on a JotForm form will make your form submissions encrypted before they are submitted to JotForm servers.
