Hello,
Thank you for submitting a question about purchasing an SSL.
We offer a single option for SSLs because we only purchase a specific type from our provider.
As for how they appear, each browser displays SSL status slightly differently. The SSL we provide typically shows up as a lock icon. The green bar you ask about is a different SSL, the EVSSL, and can be purchased by a third party if you like. We can install that for you.
You can learn all about our SSLs at our SSL info center.
Kindest Regards,
Scott M
