eBook - Beginner's Guide to SSL Certificates

"Beginner's Guide to SSL Certificates: Making the Best Choice When Considering Your Online Security Options"

SSL stands for “Secure Socket Layer.” It is a technology that establishes a secure session link between the visitor's web browser and your website so that all communications transmitted through this link are encrypted and are, therefore, secure. SSL is also used for transmitting secure email, secure files, and other forms of information.

Whether you are an individual or a company, you should approach online security in the same way that you would approach physical security for your home or business. Not only does it make you feel safer but it also protects people who visit your home, place of business, or website. It is important to understand the potential risks and then make sure you are fully protected against them. In the fast-paced world of technology, it is not always easy to stay abreast of the latest advancements. For this reason it is wise to partner with a reputable Internet security company.
