Start with the main domain and subdomains to avoid incomplete coverage.
What is wildcard SSL?
One pattern for several subdomains at the same level.
In a wildcard certificate, the asterisk represents one level of a name. For example, *.suaempresa.example can match www.suaempresa.example and loja.suaempresa.example.
Example pattern*.suaempresa.example
Compare a name with the example pattern.
Coverage depends on the full name.
Compare the first level, the main domain and a deeper name. The distinction matters when selecting a certificate.
www and loja can share the same pattern.
*.suaempresa.example matches one label before the domain, such as www or loja. The certificate must still be valid, installed and trusted.
*.suaempresa.example
www or loja
Same name level
The wildcard alone does not cover the root.
suaempresa.example must be listed as a covered name, for example as an additional SAN. Check the selected product’s coverage.
Main domain
Additional name checked
Product coverage confirmed
api.loja goes one level deeper.
*.suaempresa.example does not match api.loja.suaempresa.example. That name may need separate coverage or another included pattern.

Coverage and validation
Name coverage and organization validation are different things. Check the certificate’s validation type too.

What to know before you choose.
Does wildcard SSL cover any domain?
No. The pattern applies to the specified domain and level. Other domains need coverage that includes them.
Does a certificate make a website immune to attacks?
No. HTTPS protects the connection and helps authenticate the destination. Updates, passwords, permissions and application security remain necessary.
Does this page’s example check my certificate?
No. It compares a name with an example pattern. A real website requires checking its installed certificate, names, validity and trust chain.
