HTTPS, or HyperText Transfer Protocol Secure, is basically a secure version of HTTP, which is the protocol through which data is sent and received between your web browser and the website you are connected to. HTTPS differs from the generic HTTP by ensuring that all communications between your browser and the website and entirely encrypted to protect sensitive information and data. Website owners can secure their site through the installation of an SSL Certificate.
When a website is loaded, a normal HTTP connection will be unsecured when sending and receiving data between the user’s browser and the website’s server, which means that it’s susceptible to a cyber attack through one of the many vulnerability types. Instead, when a website is loaded via secure HTTPS, all sent and received data will be transmitted via an encrypted connection, which means that there’s far less chance of an attacker exploiting any known vulnerabilities with the website or server.
