Frequently asked questions

What is the difference between Domain Validation (DV), Organisation Validation (OV) and Extended Validation (EV) certificates?

Domain Validation (DV) certificates only verify domain ownership, are fastest to issue and cheapest; Organisation Validation (OV) certificates verify the organisation's identity and show company details; Extended Validation (EV) certificates require thorough vetting and display the company name prominently in the browser address bar, building maximum trust.

How long do SSL certificates typically last and when should I renew?

SSL certificates now last a maximum of 13 months from issuance (reduced from 3 years for security reasons). Most providers recommend renewing 30 days before expiration. Automated renewal services like those from Let's Encrypt handle this automatically to prevent outages.

Can I use the same SSL certificate on multiple domains?

Yes, through Wildcard certificates (covering all subdomains of one domain) or Subject Alternative Name (SAN)/Multi-Domain certificates (covering multiple unrelated domains). Single-domain certificates apply to one domain only. Pricing varies by certificate type and quantity of domains.
