The type of SSL you choose will depend on what sort of website you have and how many domains and subdomains you need to protect.
If you have a personal or hobby website, then a Domain validation (DV) certificate should be sufficient for you – your site will be protected and will show as secure.
For business and organisations who want to build trust with visitors and prove their authenticity, an Organisation Validation (OV) certificate is ideal. Sectigo will verify you are a registered business and your SSL certificate will be issued within 5 days.
For ecommerce sites or those that process customer details, you will need an Extended validation (EV) certificate as they offer the highest level of protection and promote the most trust for your website.
Wildcard certificates cover your website domain and unlimited subdomains, so if you need to protect more than just one domain, this will be the certificate to choose.
