Secure or SSL Forms are for secure communications between the client (i.e the end user of your form) & Tudodesk's servers. These communications are encrypted to prevent snooping by a 3rd party, this will make the communication between the server and client secure.
If you don't have a secure web server (i.e your website's address doesn't start with https) and you embed our secure web-form into the web-page, the end user's web browser will report the connection as not being secure. In this scenario, it may be better to provide a link to the form using it's Tudodesk direct link URL.
