We migrated all of our Marketo landing page SSL encryption last year. All of our forms were placed on Marketo landing pages and included on our website via iframes. We are now using embedded forms (not iframes). Is the data that's submitted via the Marketo forms still encrypted? Or would that require us to apply SSL encryption on the pages of our external website?

I am new to Marketo so still trying to get to grips with the details, so please excuse my simple question. In basic terms, please can you confirm that if my website DOES already have HTTPS encryption, i can use the embed code from Marketo forms (created in 2018) within my website and those forms will operate as expected, without errors, passing encrypted data into Marketo, (and not flag any issues in Google), WITHOUT the need for me to purchase separate HTTPS encryption module from Marketo?Many thanksMark
