How do I order and install an SSL certificate?
The validation process for DV, OV and EV certificates is slightly different. OV certificates require stronger validation than DV ones, and EV certificates require the most. You can read more about the validation process in this article (for DV and OV certificates) and in the Knowledge Base (for EV certificates).
After your certificate is validated, you will need to install it on the hosting server where your website is hosted. You can find tutorials on how to do this in the Knowledge Base. After your SSL certificate is installed, it will immediately be effective.
