"Go Daddy has shown steady growth since emerging as a certificate authority and continues to add new SSL-secured sites faster than any other host," says Rich Miller, an analyst for Netcraft. "As a growing number of Web site operators seek to add e-commerce capabilities, Go Daddy's SSL offering has proven to be a popular way for hosting customers to secure their sites."

Go Daddy says it became a certificate authority just three years ago and by 2006, the company dominated SSL hosting growth, leading the competition in 11 of the 12 months. GoDaddy offers its SSL certificates in three assurance validation levels, Turbo, High Assurance and the new Extended Validation.

Go Daddy recently announced it was hit with "significant and sustained" distributed denial-of-service attacks resulting in four to five hours of intermittent service disruptions.
