How SSL validation levels differ, how long issuance takes, and when you need a wildcard.
Every SSL certificate encrypts the connection with the same strength and shows the padlock in the browser. What differs is how thoroughly the issuer checks who you are before issuing it.
Three validation levels
| Type | What is checked | Good for |
|---|---|---|
| DV | Domain ownership only | Company profiles, blogs, landing pages |
| OV | Domain and organisation | Online stores, company portals |
| EV | The strictest checks | Finance, high-value transactions |
DV is usually issued within minutes because proving domain ownership is enough. OV and EV require document checks, so they take a few working days.
When do you need a wildcard?
A regular certificate covers one domain (e.g. namausaha.com and www.namausaha.com). A wildcard covers every subdomain at one level, such as shop.namausaha.com and blog.namausaha.com, which is handier when you have many subdomains.
For most small businesses, DV is enough. Choose OV or EV if you want your organisation's name on the certificate. Full prices are on the SSL page.
