Questions

Frequently asked questions

What domains does a Wildcard SSL cover?
A Wildcard SSL covers the primary domain and all first-level subdomains — *.yourdomain.com. That includes www, blog, shop, api, and any others you add. It does not cover second-level subdomains such as sub.blog.yourdomain.com.
How many subdomains can I add?
Unlimited. The wildcard notation *.yourdomain.com matches any single subdomain label, so you can create as many as you need without any extra charge.
Does it cover the naked domain (yourdomain.com)?
Yes. The certificate covers both *.yourdomain.com and yourdomain.com (the apex domain), so the root and www are both secured.
Can I install it on multiple servers?
Yes. Your Wildcard SSL includes unlimited server licenses, so you can deploy the same certificate across any number of servers, load balancers, or cloud nodes.
Do I need a new certificate when I add a subdomain?
No. Any new subdomain is automatically covered under the wildcard — no reissue or extra cost required.

One certificate. Every subdomain. Done.

Secure your whole domain in minutes — no per-subdomain juggling.
