SSL means Secure Sockets Layer. It's a web security protocol; and it's essentially for protecting your site visitors' sensitive data against fraud and identity theft. An SSL work in two ways. First, it guard data by providing encryption (scrambling of data to prevent tampering during transmission). Secondly, it validate the entity (verification of the business behind the website). SSL certificates come in different levels of security, depending on the level of protection and security features you are looking for. Often, all of these features are very obvious - https, Site Seals, and the "green bar" are all visual indicators of a protected site. At other times, they are behind-the-scenes. No matter what level you choose, SSL protection reassures both customers and visitors that your site is safe. That's greater customer trust and increased reliability for your brand! And, that's what we call: Get Protection, Get Verified & Validated and Get Trusted by your customers and visitors!!
WHAT TO CONSIDER WHEN DECIDING ON AN SSL
When choosing an SSL, you need to consider the domain validation you want or the number of domain you want to secure with the SSL. A third consideration is the Certificate Authority (CA). A CA is an organization that is entrusted with signing of digital certifictes such as an SSL certificate.
The Wildcard SSL certificates provide security for multiple subdomains of a single domain. For example, a wildcard SSL issued to *.mysite.com can be used to secure hostnames such as, mysite.com, www.mysite.com, login.mysite.com, mail.mysite.com
A multi-domain SSL certificate will 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, www.blog.mysite.org
