SSL (Secure Socket Layer) encryption lets you make all of your landing pages for a Marketo instance secure.
When you fill out a web form or visit a landing page that’s hosted by Marketo, by default the information is sent over non-secure protocol (HTTP). Per your company’s policy, you may want to secure the information submitted to Marketo over (HTTPS). For example, when you visit
http://info.mydomain.com/ it will now be
Marketo tracks “Visited Web Page” and “Click Link on Web Page” by default over non-secure HTTP protocol. If you want to have your tracking links secured with their own certificate, you need to have Marketo build a separate non-shared server to enable it. To secure all aspects of a contact’s interaction with you typically means securing both landing pages and tracking links.
