The Comodo Premium SSL WildCard is an organisation-validated (OV) wildcard certificate. It secures one main domain and every subdomain beneath it with a single certificate, and because it is OV rather than domain-only, the issuing authority verifies that your business or organisation actually exists before the certificate is signed. That makes it a good fit when you run a busy hostname tree (shop, blog, app, mail, staging) under one brand and want visitors, and their browsers, to trust it.

What "wildcard" actually means

A standard certificate secures the exact hostnames you list. A wildcard secures the base domain plus any single-level subdomain under it automatically, so you do not buy or install a separate certificate every time you add www, shop, blog, api, or a new client subdomain. For an operator running many hostnames under one registered domain, that is one certificate to renew instead of a dozen, and no gap where a freshly added subdomain is left without HTTPS.

Why choose OV over a domain-validated certificate

Domain-validated (DV) certificates only prove that you control the domain and issue in minutes. Organisation Validation goes further: the certificate authority confirms your organisation is real and registered, and that detail is embedded in the certificate itself. Nothing changes visually for most visitors, but anyone who inspects the certificate sees a verified organisation rather than an anonymous domain. The trade-off is the 1 to 3 day issuance window while those checks are carried out, and the fact that OV does not give you the green company-name bar, that was only ever a feature of Extended Validation, which modern browsers have largely retired from the address bar anyway.

Encryption and compatibility

The certificate can be issued at 128-bit or 256-bit strength on a 2048-bit root, which meets current expectations for public web traffic. With 99.3% browser compatibility and full mobile support, it works across the browsers and devices your visitors actually use, so you are not chasing trust warnings on older clients. If you want to sanity-check your final server-side configuration (protocols and cipher suites), Mozilla publishes a reference at ssl-config.mozilla.org.

Ordering, reissuance and refunds

Because reissuance is unlimited for the life of the certificate, you can regenerate it if you change servers, rotate a private key, or need to correct the certificate signing request without paying again. Every order is also backed by a 15-day money-back guarantee. Allow 1 to 3 days for the organisation validation to complete after you submit your request and paperwork.

Fitting SSL into a multi-site setup

If you run a network of sites rather than a single brand, remember that a wildcard covers subdomains of one registered domain, not separate domains. Each distinct domain still needs its own certificate. This pairs naturally with dedicated-IP SEO web hosting, where each property already sits on its own address and footprint. To compare this certificate against the other domain-validated and wildcard options, see our full SSL certificates range, and the SSL certificates FAQ hub covers common validation and installation questions.
