The difference between MonsterCommerce Shared SSL site security and having your own....
All MonsterCommerce clients are provided with shared 128-bit SSL Security as part of their MonsterCommerce shopping cart package.

With shared SSL security, shoppers remain on www.yourdomain.com until they begin the checkout process. Once they begin the check-out process, they get forwarded to MonsterCommerce shared SSL.

Your checkout page URL will appear as follows:

https://secure1.monstercommerce.com/www_YOURSITE_com/checkout.asp

If you purchase your own GeoTrust SSL certificate, your checkout page will remain within your domain and the URL will appear as follows:

https://www.yoursite.com/checkout.asp

You will also be provided with a "True Site Validation Seal."

When clicked, a pop-up window will display your site's Secure Status.
