If users are using your browser to access a page, they’re doing more than just simply clicking on an article. The digital fingerprint is not the only way that online activities can be recorded by undetected cookies and tracking tools. It’s becoming more and more common for users to leave their information deliberately either in social network posts and forums, or when they subscribe to newsletters. In many cases, you need to enter your e-mail address and sometimes you’re asked for even more sensitive information.
This data (passwords, user data, addresses, or bank details) is generally transferred from the browser to the database of the respective website using the HTTP protocol. This protocol has been providing excellent service since the web began, but it can miss an encryption of transported information. This means that data packets, which are transferred through an HTTP connection and intercepted on their way between the browser and webserver, are in plain text. This makes it a lot easier for cybercriminals to get access to log-in data for your e-mail account, your online banking account, or your home address. By implementing a SSL/TLS certificate, website operators can be sure that all communicated data is transferred encrypted and is therefore protected from any third parties that wish to get their hands on it.
