Find the right SSL certificate for your website

From basic encryption to full business verification.

Domain Validated (DV)

If you run a personal website or blog, Domain Validated SSL is all you need. All traffic is encrypted, though no business identity check is required. For eCommerce or any site handling sensitive data, step up to OV or EV.

Organization Validated (OV)

OV verifies both your domain and your organization — protecting you and your customers from phishing. Ideal for any site that handles customer data, with Extended Validation recommended for payment processing.

Extended Validation (EV)

For the highest level of trust, choose Extended Validation. EV certificates verify your business identity in depth — the standard for banks, large eCommerce platforms, and government organizations.

SSL/TLS certificates — FAQs

SSL stands for Secure Socket Layer. It is a security protocol that conveys your communications over the Internet in an encrypted form.
