Does adding a form to a landing page change the webpage status from secure to not secure?

[Julie_Gederos]

I'm new to Marketo and am inviting people to RSVP to a dinner via a Marketo landing page and form. The landing page that houses the form is showing has Not Secure even though it should be secure because we purchased and implemented the CNAME & SSL for landing pages. As proof, I included a link to one of our landing pages that is secure. See links below and attached screenshot. Thank you!

No, adding a form (which must be loaded over SSL if the main document is SSL, it simply won't work otherwise) does not change the security of the environment.

Not everyone can see attachments, so please remove the attachment and paste the image inline. The error shown in your screen doesn't occur when the page is viewed publicly in modern browsers. What exact browser + version is that in your screenshot?

How long ago did you change to SSL? Clear your cookies/cache and try again. It loaded fine for me.

Yep, it was working fine when I tested just seconds after Julie posted. 

Most likely there had been an insecure asset (not the Forms 2.0 assets, which load via protocol-relative URL on LPs so can never be less secure than the main document).

After some investigation, I discovered that our designer created the templates with style sheets that were embedded as http not https. Issue resolved! Thank you all.

Yep, see my comment about an insecure asset.
