What is SSL Certificates?
An SSL certificate acts as third-party verification for a website’s security. It verifies the strength of the Secure Socket Layer encryption used when a user connects to the site and connects that encryption to the organization or individual that owns and maintains the website. SSL certification and validation are a necessary piece of web security for any business that collects information from its users.
Different SSL certificates provide different levels of security, depending on the level of protection and security features your website and its users need. You may be familiar with visual elements such as Site Seals, the HTTPS:// protocol appearing in the URL, but there are less-visible functions that help protect your website and visitors.
No matter what level of security you choose, your users will recognize that your site is safe, and that leads to greater trust in your brand online.
How to choose SSL Certificates
Level of validation
Domain Validation (DV)
Perfect for blogs or personal websites. It does not verify the site owner information and is not recommended to be used for e-Commerce or sites that have a user login
Organization Validation (OV)
Ideal for securing sites that take in customer info and require login credentials. Site owner information is verified by the Certificate Authority.
Extended Validation (EV)
Recommended for sites requiring encryption for more sensitive customer information, such as credit cards. Site owner information is more thoroughly vetted by the Certificate Authority.
Number of domain secured
Single Domain SSL
Single domain SSL certificates provide security for a single unique domain name or one subdomain. For example:
domain.com or domain.us or domain.org or subdomain1.domain.com or subdomain2.domain.com
Wildcard SSL certificates allow site owners to provide security for multiple subdomains on a single unique domain. A wildcard SSL certificate issued to *.domain.com can be used to secure hostnames such as:
domain.com; www.domain.com; login.domain.com; mail.domain.com
Site managers with multiple domains can use a multi-domain SSL certificate to secure several websites by including many domains on one certificate. It's ideal for organizations with multiple unique domains hosted on a single server. For example:
blog.mysite.com, secure.mysite.co.uk, payment.mysite.net, blog.mysite.org
