February 15, 2026 - 10 min read
When you start researching SSL certificates, you quickly discover that not all certificates are the same. There are different validation levels, different coverage scopes, and wildly different price points. This guide breaks down every major type of SSL certificate.
Domain Validated (DV) Certificates
Domain Validated certificates are the most common type. The CA verifies only that you control the domain name. DV certificates are typically issued within minutes and cost nothing from providers like Let's Encrypt. The encryption strength is identical to more expensive certificate types.
Best for: personal websites, blogs, small business sites, web applications, APIs, and the vast majority of websites.
Organization Validated (OV) Certificates
OV certificates require the CA to verify your organization's identity in addition to domain control. This includes checking business registration, address, and phone number. OV certificates cost $50 to $200 per year.
Best for: medium to large businesses that want verified organizational identity in their certificate details.
Extended Validation (EV) Certificates
EV certificates require the most rigorous validation process. The CA verifies legal, physical, and operational existence of the organization. EV certificates cost $100 to $1,000+ per year.
Best for: financial institutions, large e-commerce sites, and organizations that need the highest level of visible trust.
Wildcard Certificates
A wildcard certificate covers a domain and all its subdomains. For example, *.example.com covers blog.example.com, app.example.com, and any other subdomain. You can get free wildcard DV certificates from freesslcert.net.
Multi-Domain (SAN) Certificates
SAN certificates cover multiple distinct domain names in a single certificate. For example, one certificate can cover example.com, example.org, and example.net.
