An SSL Certificate (Secure Sockets Layer) creates a secure link between a website and a visitor’s browser by ensuring that all information passed between the two remains private and secure, SSL encryption prevents hackers from stealing private information such as credit card numbers, names and addresses.
If you sell products or services on your website and accept credit cards online, you should have an SSL Certificate for website security.
You can usually purchase your SSL Certificate through your website host. When purchasing your certificate be aware that there are three basic types of SSL Certificates. They also vary in price range from about $50 to $500 depending on your hosting company.
1. Standard SSL – this SSL is valid for a single domain name (domain.com) and its www subdomain (www.domain.com).
2. WildCard SSL – this SSL is valid for one domain name (domain.com) and for all first level subdomains for it (www.domain.com, test.domain.com, anything.domain.com, etc)
3. EV SSL – Only EV SSL provides the most advanced authentication that turns the address bar green and adds the company name to it to indicate the highest possible level of validation your website has. This SSL is also valid for a single domain name (domain.com) and for its www subdomain (www.domain.com).
