If I embed my form with HTML to wix, is it secure?

I want to make sure my forms are secure. I built my form and I want to have them on my wix site, so I embedded the HTML code. Wix is not a secure site though - so does that mean the information coming from that site is unsecure? If so, is there a way I can just have someone click a button and be taken to a secure site? Thanks!
