We use Extended Validation so we had to provide our own certificate. We still had to purchase Secured Domains for Landing Pages (this was in July or August).
Yes I confirm, we had to purchase the service of Marketo "Secured Domain for Landing Pages" to have secured landing pages even if we have a renewal of our SSL certificates for our website.
How much were you quoted for the Marketo SSL certificate?
We were quote $1,100 per domain.
