Different test processes
The certificates mainly differ in the test processes carried out by the certification authorities.
Domain SSL and Domain SSL Wildcard
These certifications require a “Domain Validation”: An email with information about the validation is sent to a specific email address. This domain validation generally lasts 5-15 minutes
Organisation SSL and Organisation SSL Wildcard
These certifications require an “Organisation Validation” for which externally accessible sources and specially requested documents from the company are used. This validation method is much more stringent than Domain Validation; it also alerts the site visitors to the accuracy of the business-related data. An Organisation Validation generally lasts 1 day to 3 weeks.
When an SSL requires an “Extended Validation” it consists of a thorough examination of externally accessible sources and specially requested documents – after defined criteria of the guideline for the Extended Validation. An Extended Validation is the strictest validation method and shows your site visitors the highest level of professionalism and shows the superior reliability of the website by displaying the "green address bar" in the browser. An Extended Validation generally lasts 1 week to 3 weeks.
