SSL (Secure Socket Layer) certificates are the talk of the town. You cannot confirm a website’s security or e-commerce business that does not have an authentic SSL certificate installed on its site. It allows secure communication between a server and a user. Without SSL certificates, both the user’s info and the website resources can easily be accessed and used by the attackers for malicious purposes. So, the use of SSL certificates has become mandatory for all the sites to operate securely.
There are multiple kinds of SSL certificates, and you can select any one of them for your corporate website. Here is a short description of different sorts of SSL certificates:
- Single Domain Certificate – These types of SSL certificates secure one domain only. You cannot protect any subdomains with this certificate – just the one “hard listing” on the SSL certificate. However, all the pages on that domain are well protected with this certificate. For example, if a domain named “www.123.com” has installed a single-domain SSL certificate. Then “123.com/pages” will also be secured by this certificate.
- Wildcard SSL Certificate – You can use this certificate if you are handling a single domain and multiple subdomains. You can protect up to hundred subdomains under a single certificate. For instance, if a Wildcard SSL certificate is activated on a domain www.123.com, then all its subdomains like “blogs.123.com”, “developers.123.com”, and “partners.123.com” will also be secured.
- Multi-Domain SSL Certificates – This certificate helps protect several domains and their subdomains. With this single certificate, you can defend all the websites and their subdomains. So, you do not have to deal with purchasing a new certificate for every domain.
