A wildcard SSL certificate costs $56.33 to $246.66 per year for DV and $120 to $3,333.33 per year for OV, on a 3-year plan. Brand and warranty set the price within each range; shorter terms cost more per year. The cheapest wildcard costs $69 for 1 year (Sectigo PositiveSSL Wildcard).

Nested subdomains and other domains. A certificate for *.example.com covers mail.example.com but not inbox.mail.example.com or example.net. For nested coverage or multiple base domains, choose a multi-domain wildcard, the only product type that handles both at once.

Yes, on Renewal SSL’s wildcard certificates. The asterisk in *.example.com doesn’t match example.com on its own, so the base domain is added to the certificate as a second name. One wildcard certificate then secures example.com, www.example.com, and every other first-level subdomain.

No. Extended Validation requires every domain on the certificate to be verified individually, which rules out wildcard scope. If you want EV trust on your main site plus wildcard coverage for subdomains, pair an EV single-domain certificate with an OV wildcard.

No. Wildcard certificates are still defined and issued under the CA/Browser Forum’s Baseline Requirements. What’s changing is how you manage them: shorter maximum validity, more frequent domain validation, and the end of email validation on March 15, 2028, which leaves DNS validation for wildcards.

Not in their encryption, which is the same as any other certificate’s (256-bit AES). The operational consideration is the shared private key: every server that uses the certificate holds it, so a leak on one server affects every subdomain it covers. Install it on as few servers as you need and protect each copy.

DV wildcards issue in about 5 minutes once domain control validation is done, and a DNS record is the quickest way to do it. OV wildcards take 1 to 3 business days because the certificate authority also verifies your business.

Yes, with no per-server fees. Export the certificate, private key, and intermediate chain from the first installation and import them on each additional host. Renewal SSL imposes no server count limit on any wildcard product.
