A web hosting service is a type of Internet hosting service that allows you to make your website accessible via the World Wide Web. With this service, you also receive your SSL; which is, Transport Layer Security, and its now-deprecated predecessor, Secure Sockets Layer, are cryptographic protocols designed to provide communications security over a computer network. Several versions of the protocols find widespread use in applications such as web browsing, email, instant messaging, and voice over IP. Although this is a much needed security, and has recently become mandatory, it is still highly recommended that you also purchase a Firewall. Firewall is a must-have if you have public users on your site; for example, a membership site, or any site where your users input their information. Without a firewall your user’s information can be hacked.
