Which SSL certificate does your site actually need
DV, OV, EV, Wildcard or Multi-Domain? A plain-language guide to picking the right SSL certificate without overpaying.
Every site today needs HTTPS. Browsers flag plain HTTP as “Not secure”, search engines prefer encrypted sites, and modern features (from payment forms to service workers) simply refuse to run without it. The question is not whether you need an SSL certificate, but which one.
Validation level: DV, OV or EV
The three letters describe how thoroughly the certificate authority checks who you are before issuing the certificate.
- DV (Domain Validation) - proves you control the domain. Issued in minutes, no paperwork. Perfect for blogs, portfolios and most small business sites.
- OV (Organization Validation) - the authority also verifies your company exists. The organization name is visible in the certificate details. A good fit for company and e-shop sites that want extra trust.
- EV (Extended Validation) - the strictest checks. Used by banks and large e-shops where trust is everything.
For visitors the padlock looks the same at every level. The difference is in what the certificate asserts about you, not in the strength of the encryption - that is identical across all three.
Covering more than one name
A standard certificate secures a single hostname, for example yourdom.eu plus www.yourdom.eu. Two other types handle bigger setups:
- Wildcard - secures every subdomain of one domain:
shop.yourdom.eu,blog.yourdom.eu,api.yourdom.euand so on, all with one certificate. - Multi-Domain (SAN) - secures several different domains under a single certificate, handy when you run related sites together.
How to choose in one minute
- One site, one domain, you just need the padlock? DV.
- Company or e-shop that wants its verified name on the certificate? OV.
- Many subdomains under one domain? Add Wildcard.
- Several separate domains at once? Multi-Domain.
Encryption strength is the same everywhere. Pick the level of identity your visitors need to trust, not the most expensive option by default.
