Wildcard SSL - Definition & Benefits!

A Wildcard SSL certificate is a digital certificate that establishes a private connection between web servers and web browsers.

It provides authentication and encryption for several hosts that share the same sub-domain level.

Adding an asterisk (*) and a period (.) in the sub-domain area that is before the domain name will secure the sub-domain name. (

Wildcard SSL certificates offer numerous benefits. The advantages include:

Nick Tepesch
Ahead of its time

I upgraded to Comodo's Wildcard SSL certificate after sampling their free SSL certificate for 90 days. Their signing technology is ahead of time. My vote is for Comodo Wildcard.

No more Wildcard hopping

Being the sys admin head of a large IT company, I purposely went around trying out every Wildcard Certs from different providers. I find Comodo's Wildcard SSL technologically advanced and now our company stick with it.

Marlenis Costa
None other

Comodo's SSL and Wildcard, both are equally good and provide the same bit encryption strength. Thanks Jacob from the customer support team who helped me install it by myself.

Charles Pahud
Slightly overpriced

Comodo's Wildcard is best in the industry. But the cost is a little expensive for small business owners like myself. Maybe that's because I used their free SSL for so long.
