Domain Validation SSL/TLS certificates are a great option for securing personal websites, blogs and other non-e-commerce sites. The process for validation is simple and painless. You simply must prove to the Certificate Authority (CA) that you own the domain that was applied for. This can be done within minutes via email, allowing the certificate to be issued within minutes of purchase and then installed immediately. Domain Validation certificates offer the same level of encryption strength as Organization Validation (OV) and Extended Validation (EV) certificates, but lack the authentication aspect which helps to provide customers with a greater degree of trust. It also does not activate all of the SSL or "trust" indicators within the browsers; such as the trusted green address bar. To activate the green bar and make your site more trustworthy, you should consider an EV certificate. If you're running an e-commerce site or a website that collects user information, you'll definitely want to consider and OV or EV certificate.
