| Type | What is validated | Issuance | Best for |
|---|---|---|---|
| DV (Domain) | That you control the domain | Minutes | Blogs, portfolios, brochure sites |
| OV (Organization) | The domain and that your company legally exists | 1 to 3 days | Businesses, forms, client areas |
| EV (Extended) | Full company validation | 1 to 5 days | Banks, lenders, e-commerce |
All provide the same encryption; they differ in how much the holder's identity is verified, the warranty and the trust they convey.
There are also Wildcard certificates (cover all subdomains, like *.yourdomain.com) and Multi-domain ones (several domains in one certificate).
