Quick answer
- Most blogs and small business sites don’t need to buy an SSL certificate. A free certificate (such as Let’s Encrypt) gives the same encryption.
- Most web hosts install and renew a free SSL certificate automatically.
- Paid certificates add things like organization validation, warranties and support. Some businesses need these for compliance or trust.
- You can buy paid certificates from certificate authorities, resellers or your host.
An SSL certificate turns on HTTPS and the padlock in the browser. The good news: for most websites, it’s free. Here’s when you might want to pay, and where to buy.
What is an SSL certificate?
It’s a small data file that proves your site’s identity and lets browsers set up an encrypted (HTTPS) connection. Today it’s technically TLS, but everyone still calls it SSL.
Types of SSL certificates
| Type | What it checks | Good for |
|---|---|---|
| Domain Validation (DV) | You control the domain | Blogs, most websites |
| Organization Validation (OV) | Domain plus company details | Businesses that want verified details |
| Extended Validation (EV) | Stricter company checks | Large companies, finance |
| Wildcard | Covers all subdomains | Sites with many subdomains |
| Multi-domain (SAN) | Several domains in one | Businesses with several sites |
Free SSL: is it good enough?
Yes, for most sites. Let’s Encrypt is a free, nonprofit certificate authority, and its certificates provide the same encryption strength as paid DV certificates. Hosts that use it renew them automatically.
When to buy a paid certificate
- You need OV or EV validation.
- You need a warranty or vendor support.
- Your host doesn’t support free certificates on your setup.
- Your compliance rules require it.
Where to buy an SSL certificate
- Your web host: simplest, as they install it for you. Some higher plans include a premium SSL, such as Hosting.com’s Max plan (checked November 2026).
- Certificate authorities: such as DigiCert or Sectigo.
- Resellers and registrars: often cheaper for the same certificates.
After installing SSL
- Force HTTPS and redirect HTTP.
- Fix mixed content warnings (images or scripts loaded over HTTP).
- Update your site address in Google Search Console.
