Browser Displays “Not Secure” Warning When Viewing Marketo Landing Pages

Description description

For instance, if your primary domain is https://www.mycompany.com (SSL secure), then the DNS, which is also SSL secure, will push down the https transfer protocol to all the CNAMEs on that DNS. This will force the Marketo landing page using the CNAME to use https in the URL, even though it is not secure.

There are two ways to resolve this:

If you would like to add SSL to your Marketo instance, please contact your Account Manager to see about adding that to your subscription.
